1. Late Ordovician Life [C-55]

"In the clear shallow waters of the Late Ordovician inland sea there lived an abundance of marine invertebrate animals. Even 400 million years ago the seas were supporting their full quota of living things, although so far as we know nothing inhabited the lands. Found in the Frederick J.V. Skiff Hall (37).”

2. Restoration of a Group of Mesohippus, a Three-Toed Horse

“These little horses, which lived in the western United States about thirty million years ago, differed in many ways from modern horses. They were smaller, being less than two feet high and had three toes instead of one on each foot, as in the modern horse. The name Mesohippus means “middle horse” and is applied to indicate that they were midway in descent from a five-toed ancestor to the one-toed modern horse. Group by Frederick Blaschke. Background by C.A. Corwin. Found in the Ernest R. Graham Hall.”
