Its main focus is the rich, high-quality taxidermy collection used to educate people about animals and their habitats, as well as environmental issues. The collection is also – as the name and affiliation of the museum implies – heavily used for biodiversity and zoology research. The museum was named after its founder Prof. Alexander Koenig, who worked on zoology with an expertise in bird biodiversity in the 19th and early 20th century. The museum still hosts many specimens that were collected by Koenig himself (for example two giraffes and many bird eggs).
Upon entering the building, visitors are greeted by a quite impressive diorama of African savanna fauna and flora ensembles, with naturalized pieces in dynamic poses (Fig. 1). Each animal seems almost alive, with real water dripping out of the mouth of a zebra drinking in a pond, while a leopard bites an antelope’s throat.
In addition to telling interesting stories, the diorama scenes allow the spectators to learn more about animals’ habits and behaviors. Often, audio tracks of both animal and environmental sounds are played in the background and many information sheets and panels (in German and English) are displayed on a variety of scientific topics.
In the next room you find yourself in a tropical jungle, where light effects play a huge role in the display of the naturalized specimens (Fig. 2). Here, the interactions between animals, plants and their environment are the main focus of the dioramas. The extremely realistic appearance of plants inside the cases is fascinating, as each and every of the hundreds of thousands leaves and twigs are actually plastic replicas that were hand painted by skilled artists, no two leaves are the same. In the dark forest, you can sit and watch short documentaries about apes or listen to an audio guide explaining interactions between ants and mushrooms in the tropical forests. The day we visited, on the first floor, we couldn’t visit the canopy of the rainforest, as the displays were still under construction. It has since then been opened to the public: A massive forest canopy diorama and multiple activities educating visitors further about the impact humans have on the rainforest, and people taking action to protect it.
The museum then takes you along on a trip around the world, from Antarctica (seemingly the oldest part of the permanent exhibition, that maybe needs to be updated a little bit from a public outreach point of view, especially when compared to the brilliantly done new tropical forest exhibition) to the deserts, which has surprising and very educative, interactive displays (Fig. 3).
A substantial part of the permanent exhibition is dedicated to the history of the museum and the problems associated with it (e.g. colonialism), and its historic specimens (Fig. 4). This section also tackles the role of humans in the disappearance of species and the destruction of natural habitats. These themes, along with other important topics such as climate change, are brought up in several instances all across the museum. Visitors are invited to sit at the ‘consumer’s table’ interactive display, a great (but also eye-opening and saddening) tactile table with graphic representations that estimate and illustrate your use of natural resources and your impact as a consumer on deforestation. As you select lifestyle choices such as updating your phone for the newest model, selecting a car or public transport, choosing exotic woods over locally produced items, selecting your food choices, you can watch the forest deteriorate or heal with every choice you make (Fig. 5). On the other side of the first floor is an exhibition dedicated to the beautiful and colorful world of insects (Fig. 6). This area also gives insights into research work including an interactive exhibit of a taxonomist’s lab, including microscopes, maps, games and many many books.
Then, there’s the more ‘ancient’ part of the collection, displaying naturalized specimens in glass cases with a systematic approach (for example showing a large number of birds together regardless of their habitat), and some more amazing, though old, dioramas that transport you to the seaside, into the forest or into a field, with a focus on the local german fauna.
The museum’s top floor is dedicated to temporary exhibitions. At the time of our visit, one side consisted of a huge photograph exhibition, highlighting the beauty of nature through the seasons. The other side was dedicated to an exhibition showcasing horse evolution and especially the eocene horses of the Messel pit (Fig. 7). The main element of this exhibition was an exquisitely preserved specimen of Eurohippus; an extinct genus of a relative of modern horses, discovered in Messel. The Messel pit is an eocene maar lake in which hundreds of fossils from a large range of plant and animal species have been preserved exceptionally well (a location comparable in age, fossil assemblage, environmental conditions and depositional setting as the Eckfelder Maar we already wrote about, though much larger) – including several specimens of Eurohippus – allowing paleontologists to have a good insight into these extinct animals’ biology and life. Several specimens have been preserved so well, their internal organs could be investigated and at least 6 specimens are known to have been pregnant when they died.
In this exhibit, Eurohippus was shown both as a replica of a fossil, as well as as a reconstructed version. An entirely white model was used as a canvas, the visitors could play with different patterns and colors of light being projected on the model, mimicking extant animals’ fur patterns to show possible colorations the extinct horse relatives could have had. As the color and patterns of Eurohippus’ fur is still a mystery, this is still up to imagination (Fig. 8).
One of the previous temporary exhibitions of the Museum Koenig was called ‘Big, bigger, dinosaurs’, and because this was not only very cool, but our local paleontological preparator Blandine also got to help dismantle it in the end, we will cover this exhibition in a separate post very soon! Until then, you can already find a post on her instagram about the dismantling (together with a large range of various dinosaur-related content) @dinosaur_forensics
A bit more than half of the informative text appearing on screens and panels in the permanent exhibition is also available in English, as well as much of the audio and video content. Apparently, the museum is working on translating their content from German as they redesign display areas.
In addition to their efforts in making the museum accessible to english-speaking, we also noticed a large amount of available seating throughout all of the rooms, lifts in addition to stairs, and playing areas for children, making the museum a very welcoming environment.
We highly recommend a visit!
Here are some more impressions of our visit (Figs. 9-12):
Linda and guest bloggers Blandine (hyperlink to Meet the Scientist) and David (hyperlink to Meet the Scientist) here – in August 2021 we packed our bags, hand lenses and sunscreen, and hopped on a plane to go on a field trip in Lourinhã, Portugal [Fig. 1]. This city is known as the Portuguese capital of dinosaurs because of its fossil-rich Jurassic outcrops. It even is the eponym (name giving location) for several taxa: sauropod dinosaur genus Lourinhasaurus, theropod dinosaur genus Lourinhanosaurus, sauropod dinosaur species Supersaurus/Dinheirosauruslourinhanensis. Today, Lourinhã is located on the Portuguese Atlantic coast. While small beaches exist, the majority of the coastline consists of tall, rocky cliffs. This area looked very different during the Mesozoic Era though.
When Pangaea fell apart and the North Atlantic began to open, the Lusitanian rift basin formed due to the extension of the crust in the area that is today western Portugal. The Lusitanian basin was likely bordered by the Berlenga horst in the west and by the Central Plateau of the Iberian Peninsula (Meseta Central) in the east [Fig. 2]. During the Late Triassic, the evaporation of sea water in the Lusitanian Basin led to the deposition of a thick and ductile salt layer, which later caused instability in the overlying sediments. The formation and movement of salt domes constantly changed the topography and thus modified the course of river beds. The relative sea level at the coast of this area was fluctuating during the Jurassic, and as a result we observe layers representative of large, meandering rivers and layers richer in terrestrial plant material when the sea level was at its lowest, occasionally marine intercalations (with shallow marine fossils such as oysters) and fine, muddy deposits from entirely marine environments.
The dinosaur fauna of Portugal is similar to the ones of the Morrison Formation in the US and the Tendaguru Formation in Tanzania, with several genera, such as Allosaurus, Ceratosaurus and Torvosaurus occurring in all three localities [Fig. 3]. This is remarkable since these regions were separated by the sea during the upper Jurassic; the former supercontinent Pangaea was already breaking up. That means that a faunal exchange between North America (Morrison Formation), the island Iberia (Lourinhã Formation) and Gondwana (Tendaguru Formation) was still possible, probably in times when the sea-level was low.
Day 1) Praia de Vale Pombas and Dino Parque Lourinhã:
We spent the morning of our first day at the Praia de Vale Pombas, a small beach south of Peniche. You very quickly forget the beautiful scenery when you spot a fossil. Within minutes we found large fragments of fossilized wood and got very excited when we found bones quickly after that. Most remains were fragmented and we could not identify them, but we found a theropod metatarsal (foot) bone [Fig. 5] as well as a small piece of a rib of an unidentified animal.
Please note: while fossil collection is permitted at this specific outcrop, the different municipalities in this area handle this matter very differently, many do not allow collection by private collectors but only professional scientific excavations for which you need to file a request. Always follow the local regulations when in the field, many fossils are beautiful, but not yours to take. Also make sure to always inform the authorities when you spot something potentially important.
In the afternoon we visited the Dino Parque in Lourinhã. A small museum in the park showcases the locally found dinosaurs with original skeletons and replicas, as well as methods and techniques used in the excavation process and during fossil preparation. The largest section of the park is a huge outside area showing life size reconstructions of different dinosaur species. We received tours behind the scenes and talked to the staff and preparators who explained their work to us. This was so much fun that we wrote a separate post just about our day in this park, check it out here [hyperlink to blog post]!
Day 2) Museu da Lourinhã:
On the second day, we visited the Museu da Lourinhã, the museum of the city of Lourinhã dedicated to the region’s geological and historical heritage. In the paleontological gallery, numerous locally found dinosaur fossils, including eggs with embryos of the theropod Lourinhanosaurus are presented. The museum’s archeological and ethnological exhibitions deal with human history in the region and show how people lived here in the past.
We were given a thorough tour of the geological and paleontological section by Carla Tómas, one of the museum’s preparators, who also led us behind the scenes into the preparators’ laboratory. Here, the preparator team works on the preparation and study of local and international vertebrate remains. While we were there, Carla explained to us that her specialty is to find new methods to stabilize very fragile fossils by preparing and treating them chemically. Some geological properties can lead to poor bone preservation, for example the presence of salt can result in extremely brittle fossils. It is therefore important to understand the chemical processes happening and stop the degradation of the material to preserve the fossil.
Day 3) Ponta do Trovão, the Toarcian GSSP
Not far away from our accommodation in the town of Peniche, just north of Lourinhã, there is a GSSP [Fig. 6]. GSSP stands for Global Boundary Stratotype Section and Point and refers to physical markers between specific layers of rock, marking the lower boundary of a stratigraphic unit. For each stage on the geologic time scale, scientists are trying to identify one GSSP somewhere in the world, indicating exactly the boundary between two stages. The end/beginning of a geological stage is defined by a change, commonly a change in fossil assemblages such as an extinction event or the first appearance of an index fossil. Currently, less than 80 GSSPs have been ratified, the vast majority of which are located in Europe. The GSSP we visited is located at Ponta do Trovão in Peniche, and marks the beginning of the Toarcian (early Jurassic, 182.7 million years ago). It is defined by the very first appearance of the ammonite genus Dactylioceras (Eodactylites).
We spent the rest of the day exploring the area, looking for fossils in the layers below the GSSP (thus not in the Toarcian, but the previous stage, the Pliensbachian) and found thousands of belemnites [Fig. 7]. Belemnites are an extinct group of cephalopods, which looked similar to today’s squids but with hooks on their ten arms. They had an internal skeleton called the cone, of which only the calcitic guard (called rostrum) commonly fossilizes. In addition to belemnite rostra scattered around, we also spotted a few coprolites, the fossil remains of poop [Fig. 8]. It appears that something has been snacking on ancient “calamari”, but could not digest the hard, calcite guards. Between the large number of rostrum fragments, we also discovered a number of ammonites, some of which – especially when they were located in the intertidal zone and thus currently in contact with sea water – were beautifully pyritized [Fig. 9].
Since this is a special outcrop, a GSSP, we did not collect fossils here, but only marveled at their beauty.
Day 4) Praia Formosa, Praia de Santa Cruz, Praia Azul and excavation sites of the municipality of Torres Vedras
In the morning we joined a guided tour given by Bruno Camilo Silva, a local paleontologist. We learned about the geology at Praia Formosa and Praia de Santa Cruz, two beaches south of Peniche. The tall cliffs here show wonderful profiles of the rock layers of the Lower Jurassic, providing insight into the sedimentological history of this place. At the time, tectonic movements and underwater currents would cause sediments to slide down the Berlenga Horst from time to time. Those events formed a sediment known as turbidite, occurring here as massive conglomerates. We can see clearly where these turbiditic flows eroded the older sea-floor sediments, leaving irregular contacts between the layers [Fig. 10]. Considering that the Berlenga Horst was quite far away from the location these layers were deposited, it is difficult to imagine the sheer size of the sediment flows and the amount of material that must have been transported.
The layers below the turbidite in this area are unfortunately quite poor in body fossil content, despite numerous traces of invertebrate activity in the sediments. Based on those ichnofossils such as burrows, it is assumed the area had probably a rich benthic fauna, which has not been preserved in the sediment because the conditions were too unfavorable for fossilization. The fact that we know there was abundant life but all that’s left of it now are ichnofossils and we may never know which organisms once roamed the seabed here is quite humbling. After brooding about this, we chose to have our lunch break at Praia Azul, the blue beach. We used this occasion to search for fossils at the foot of the cliffs near the beach while eating our sandwiches. The most common fossils that can be found here are oysters, marking times of shallow marine conditions. Several large oyster banks are preserved [Fig. 10], though wood and other isolated plant fragments also occur frequently. In addition to these finds, coprolites, signs of bioturbation such as re-filled burrows, and – very rarely – small bones can be spotted in the cliffs of this beach.
In the afternoon, we visited active paleontological excavation sites, of which we promised to keep the locations secret in order to avoid people disturbing the ongoing work/research. A team composed of local volunteers, international students and experts, and employees of the municipality of Torres Vedras were excavating turtle and crocodylomorph remains. At a second location nearby an almost complete but at the moment of our visit still unidentified theropod dinosaur was excavated, ready to be covered in plaster and to be lifted and transported to a preparation lab to finally see the light of day again. Blandine picked up a rock very close to one of the sites and found a small tooth (identified by staff on site as possibly hybodontiformes, a sister taxon of sharks and rays), which she handed over to the excavation team so it can be included in the research. In the evening, to finish an exciting day, we paid another visit to Ponta do Trovão to search for fossils with the sun setting over the Berlengas archipelago, the remnant and eponym of the aforementioned Mesozoic horst structure, on the horizon [Fig. 12].
Day 5) Foz do Arelho and Parque de Merendas
While we spent most of our Portugal trip in the fossil rich localities along the coast south of Peniche, we planned to explore some places north of the city on day 5. After checking geological maps of the region in order to find promising localities we decided to head to the cliffs of Foz do Arelho first. While the place itself was a spectacular sight, we didn’t find any fossils there. So, we went further north to the cliffs of Parque de Merendas near Serra do Bouro. Again, this was an amazing locality, but with very few fossils. We found interesting green minerals on and around plant remains. Bone fossils, however, were very rare, but Blandine, our dinosaur expert, found a large fragment of a dinosaur bone that could not be further identified [Fig. 13].
Day 6) Praia de Porto Dinheiro, Praia do Zimbral and cliffs near Porto Batel
We spent the next day going to Praia de Porto Dinheiro (the town is the eponym of the dinosaur genus Dinheirosaurus) near Rebamar and to Praia do Zimbral, where we met with the local paleontologist and the geologists we had already encountered a few days earlier. While the group was excavating an unidentified fossil bone fragment, David found another piece in the rubble that had fallen from the cliff into the beach, extracted it [Fig. 14], and handed it to the local paleontologist so it could be included in their work.
For lunch we went to a local restaurant just next to Praia de Porto Dinheiro, which has a large Sauropod bone being showcased under glass plates below the floor in the entrance. The owner of the restaurant showed us a large Torvosaurus tooth from his private collection. Even the sink in the bathroom is made out of a piece of fossil oyster bank. Later that day we met again with the other geologists and paleontologists at the cliffs near Porto Batel. At this locality dinosaur footprints can be found: The group showed us large theropod tracks [Fig. 15], and the filling (negative) of a deep Sauropod footprint up in the cliff [Fig. 16]. Although way too far above for us to check, we were told that skin impressions can be found in this footprint.
All in all, our trip to Portugal was very exciting. We could observe plenty of fossils including dinosaur bones in the beautiful scenery where the Atlantic ocean is inexorably gnawing away at the rocks that once were the walking grounds of the giants of the past. If you know where to search it is impossible not to find nice fossils, though please remember: Collecting fossils is not permitted everywhere in this area! Inform yourself prior to your trip and stick to the local laws and regulations! The city of Lourinhã itself, its museum, and dinosaur park are also worth a visit; the geological heritage of the region is felt everywhere in the streets, the people in this area live and breathe dinosaurs, with many shops, restaurants, businesses and cafés including the term ‘dino’ in their names and life-size dinosaur models and art found in many places.
In case you haven’t had enough, here are some additional impressions of our trip [Fig. 17-22]:
Tell us a little bit about yourself. Hi! My name is Blandine, and I am a master’s graduate in vertebrate paleontology. I specialise on dinosaurs (taphonomy, histology). I did my geology bachelor’s degree in Lille (France) with an Erasmus+ mobility in Tomsk (Russia), followed by a master’s degree in paleontology done in Lille for the first year, and an Erasmus mobility in Bonn (Germany) for the second, with my master’s thesis. Outside of paleontology, I am interested in modern Japanese literature, gothic fiction, taking care of plants and animals. But to be honest, I’m having the most fun when I’m in a museum!
What kind of scientist are you and what do you do?My career is only beginning, and I like to try out everything related to paleontology.
For my master’s thesis, I had a research project on green-colored dinosaur bones from Utah (USA). The remains belonged to several diplodocines (large long-necked dinosaurs), and an unusual fossilization turned them green. Histology (study of bones microstructures) is a technique which has many uses, one of them being the determination of the age of an animal by the observation of its bone tissues. This method is particularly useful in bonebeds where dinosaur remains have been mixed because of river flows (for example). Through the observation of bone sections under the microscope, I could determine that the diplodocine remains came from animals of different ages, which meant several dinosaurs’ carcasses were mixed in the quarry.
Before that, during my bachelor’s, I learned dinosaur bone preparation in the vertebrate paleontology laboratory of the Tomsk State University. It’s a tedious work, but you really learn a lot by preparing the fossils by yourself. There are so many details you can miss when you observe a bone taken out of its context! The surrounding sediments, the geometry of the deposition, the state of preservation of the remains… all those clues are very important when doing a paleontological investigation! I see things in this way: a vertebrate paleontologist is often like a medical examiner in a murder case. When the body is removed from the crime scene, they are able to tell the cause of death, but not who killed the victim. To get the whole picture, we need the crime scene as well. For paleontologists, this corresponds to the quarry/bonebed, or at least the sediments around the bones. This is what field excursions, and thorough documentation on excavations are for!
During the bachelor years I had in Lille, I worked as a curating assistant for the geology department of the Museum of Natural History, and helped organising several public outreach events, giving talks on the need of paleontology in our societies to understand today’s climate emergency.
A few months ago, I helped dismantling the “Big, Bigger, Dinosaurs” exhibition at the Museum Koenig in Bonn, and returning to this kind of environment after a 3 years break felt really good. Since then, I occasionally help setting up and dismantling exhibitions around dinosaurs, and it is so much fun! (PS: I created an instagram account to try to share the behind the scenes of dinosaur research and exhibitions… @dinosaurs_forensics 😉 )
What is your favorite part about being a scientist, and how did you get interested in science? When I was a child, I developed an interest for bones early on. I would collect bones and skulls from diverse animals I would find in the fields, clean and sort them in different categories. As my mother thought this was a horrible hobby for a little girl, she got rid of my collection as soon as she found out it was not a short-lived interest. I then moved on to snail shells, but this collection was really stinky, and ended up in the trash like the former one. To me, keeping those bones and shells were like preserving memories of what once was. I wanted to understand what had happened to those animals, and their remains were a way to find out. One day, a friend of my parents showed them a plant fossil. It was a trace of a thing that lived in the past, it was beautiful, did not stink.. and my parents liked it? From that moment on, I started asking questions about fossils and collecting them. My dad brought me to the Museum of Natural History in Lille, and there I could show my treasures, get answers about them, and see which stories could be uncovered through fossil remains. I decided I would become a paleontologist one day. Growing up, I received a great support from my dad, one museum curator, and three school teachers who encouraged me to follow my passion, despite everyone around saying that I would “never make it” in paleontology.
My favorite parts about being a scientist are to question the current knowledge, go on field excursions to look for fossils in places where nature has been untouched, and also try to close the gap between scientists and the public. In the same way older people made me want to do paleontology and pushed me to follow my dreams, I want to transmit the knowledge and will to understand our world to younger generations. I love speaking to kids, grandparents, families who want to know about what was, and what extinct forms of life can tell us about our present and future.
How does your work contribute to the betterment of society in general? Dinosaurs make kids and adults dream and wonder, and even if this field of paleontology can be considered as “less meaningful” regarding climate change than micropaleontology as an example, I like researching about them just for the sake of knowledge. Why did they look this way? What were their habits? Why were they so big?
I believe there is nothing wrong in trying to answer questions which do not appear as “useful” for today’s societies. All questions deserve to be answered. On the other hand, understanding dinosaur’s ecology, biology, environment and habits definitely help us refine the knowledge we have about evolution and other aspects of the living.
Dinosaurs are also useful in another way: as they are part of the worldwide pop-culture, they are very often the first step into paleontology for many people. Through dinosaurs, it is possible to speak to people about fossils, geology, evolution, extinction events. As a result, for public outreach, scientists (including me) use them as an introduction to topics such as climate change. That’s why so many scientific articles use “dinosaur” in their title, even when those animals are not involved in the paper.
What advice do you have for up and coming scientists? “Do or do not. There is no try.” if you want to do science, go for it. Do your best, always, and if it does not work, you won’t have any regrets because you did all you could to make it happen. And when obstacles will come along the way, never forget that for each problem there is a solution. If you have passion, you will get to meet similar-minded persons who will help you reach your goals, and you will end up finding your spot in this field.
If you are a LGBTQ+, disabled, POC or woman-identifying person: there is space for you in science. Together, we should and will make this environment a safer place, where we all can grow equally. We need diversity, please don’t give up on your dreams.
