Learning from rocks

Hell Creek, MT, with rainbow

SMM's Triceratops lived in Hell Creek, Montana. We can recreate its environment, and other past environments, using all sorts of clues, including rocks.

Rocks tell stories just as well, if not better, than fossils do. Each type of rock has a "recipe," and the kinds of rocks we find in an area are clues to the conditions at the time of the rock's formation.
