The Florida mouse and gopher tortoise have been in a serious relationship for thousands of years. Theirs is a commensal one: The Florida mouse uses the gopher tortoise’s burrow as shelter from the heat, but the tortoise gains nothing. While the mouse also makes its way into other animals’

Giant Armadillos and Ground Sloths came to North America from the south during the interchange. Like most “megafauna,” they became extinct around 11,000 years ago, but are common in fossil deposits today. Summary Giant Armadillo Skull (Holmesina floridanus) From Citrus Co., Florida Lived ~1.8

Museum scientists have discovered nearly 500 Parahippus jaws from the Thomas Farm Fossil site, allowing study of differences between juveniles and adults. It’s important to understand how an organism changes within its lifetime before defining how a species evolves over time. Summary Ancient Hor

The „Grandfather“ to the modern horse, Pliohippus appears to be the source of the latest radiation in the horse family. It is believed to have given rise to Hippidion and Onohippidion, genera that thrived for a time in South American, and to Dinohippus which in turn led to Equus. Where & When
Species in this genus lived from 12-6 million years ago.

Though a relatively short epoch, tremendous events occurred during the Pliocene, such as the development of ice caps, the drying of the Mediterranean, and the joining of the Americas. Biogeographically, this epoch is characterized by the dramatic modernization of mammals. All of the presently exist
