Charlotte Hohman, Paleontology Undergraduate and Student Researcher

My name is Charlotte Hohman, and I’m a 3rd-year undergraduate at Montana State University.  I am majoring in earth sciences, with a concentration in the field of paleontology. There are  many different aspects of the field that one can be involved in, including but not limited to  research, fossil preparation, education, outreach, fieldwork, digital reconstruction, and art. I  love many different aspects of the field and am using my student years to gather experience in  those aspects and learn from a variety of mentors to prepare me for a career in the field.

I first became aware of paleontology as a scientific field in 2018 when I began volunteering at  the Western Science Center (WSC). In California, you need 40 hours of community service to  graduate high school, and I knew the museum was taking volunteers, so I signed up. I started  as a docent the summer before my senior year. In September 2018, the director had me  identify some Ice Age rodent fossils. He asked me to find a way to categorize the fossils, and I  ended up coming up with a categorization method meant to make predictions about the  ancient environment of the site during the Ice Age. The director thought the method looked  interesting and asked me if I wanted to present at a conference. I presented my preliminary  results my senior year of high school at the 2019 Geological Society of America Cordilleran  meeting, where I realized that I definitely wanted to pursue paleontology professionally.  

Since then, I have continued to do research. I conduct student research at Montana State (and  its affiliated museum Museum of the Rockies (MOR)) and the Western science center. I have  co-authored two publications: one on the Pacific mastodon’s (Mammut pacificus) geographic  range (McDonald et al., 2020), and one on the prehistoric horses of the Cajon Valley Formation  of Southern California (Stoneburg et al., 2021). My three in-progress manuscripts focus on how  dromaeosaurids (raptors) grew into adults, horses in southwestern North America during the  Ice Age, and my continued work on the aforementioned rodents!

But as I mentioned, paleontology is so much more than research, and I am involved in multiple  other aspects of the field as well. I have been able to go on digs in New Mexico in Cretaceous  rocks (79 million years old), and in Southern California in Miocene rocks (15 million years old). I  prepare fossils at both the MOR and WSC, and have been fortunate enough to clean the fossils  of whales, sauropods, bison, and more!

At the WSC, I make casts, molds, storage cradles, and create 3D models of fossils. All these  lab skills are important for the sharing of research— open-access digital models allow  researchers from around the globe to view your specimens. Casts and 3D prints are great for  outreach and education. I believe that sharing the science is equally as important as doing it,  which is why I am also active in scicomm, or science communication. Science communication  can be online, like on social media, or in-person, like at outreach events. For the WSC, I am the  illustrator of their children’s book series on scientific papers for kids. I run my own educational  account on Instagram, along with managing social media for other paleontology-focused  organizations. Many people have a natural interest in prehistoric animals, so I use science  communication about prehistoric life as a way to draw people in and introduce them to many  different concepts within earth science and biology. 

I plan on doing a Ph.D. when I am done with my bachelor’s and would like to work in a  museum setting one day, to be able to continue to do research, while continuing to share and  teach others about earth history.
