The fossils of the Paleogene encompass three Epochs. During the Paleocene, beginning 65 million years ago, small mammals diversify on land. The first marine mammals appear during the Eocene, while on land large mammals appear. The Oligocene, ending 24 million years ago, saw the first appearance of the grasses, an immensely important group in subsequent ecologies. The anthropoid apes also appeared during this epoch.
Birds diversify, occupying the niches left by the pterosaurs.
The collection's bird head , feather , and tracks are all of the Eocene Epoch. Echinoderms in this display include as sea urchin, Echinolampas kleini , and a heart urchin, Eupatagus clevi .
