Rocks and minerals are all around us everyday, everywhere we look! If it were not for minerals, for example, you wouldn’t be able to read this website on your computer, nor would you have a cell phone! Rocks and minerals also play an important role in the animal kingdom and in helping to regulate Earth’s long-term climate states.

On the Common Rocks page, we introduce you to the rocks most mentioned within this website, how they form, and where they can be found. On the Common Minerals in Biomineralization page, we review a few of the most important minerals that extinct and extant animals use to build their skeletons.
