leaf fossil

Museums don't know everything

One hundred million years ago, dinosaurs roamed much of the world. Lush forests provided homes for many species, and food for the plant-eaters.

These leaves are among the few dinosaur-age fossils from Minnesota. They fell into the water near the shore of an ancient inland sea. Covered by silt, they were preserved for millions of years, until discovered in a clay pit near New Ulm.

How were these fossils made?

Who cares about a bunch of old leaves?
