Pliocene Epoch: Geological and Biological Insights

The video explores the dramatic changes on Earth during the Pliocene Epoch, focusing on Florida. It discusses the uplift of mountain ranges, the onset of Ice Ages, and the arrival of new species like the Titanus bird. The Great American Biotic Interchange, facilitated by the Isthmus of Panama, allowed species migration between the Americas, impacting Florida's ecosystem. Fossil discoveries in Florida reveal the biodiversity of the Pliocene, highlighting both extinctions and the evolution of new species.
