context_section_description: Leon County, like most of North America, supported a variety of ancient and now extinct animals as far back as 33 million years ago. There are no fossils of dinosaurs in Florida. Prior to the Miocene, Florida was a submerged carbonate platform essentially cut off from the continent by the Gulf Trough. When this trough filled with sediments during the Eocene—Miocene, the carbonate Florida Platform collected sediments and became exposed allowing flora and fauna to take hold. Proto dogs and bear-dogs, along with large cats and other carnivores migrated to the peninsula following their prey of ancient ruminants and deer-like mammals.
