Early Cenozoic Life- Megalodon Roamed, Mammals go Back to Sea, Huge Birds Hunt Horses | GEO GIRL

Описание: The Early Cenozoic Era, in the Paleogene period, was characterized by whales learning to swim after evolving from carivorous land mammals, huge sharks including Carcharadon megalodon, corals diversifying and taking over reef building, sand dollars and burrowing bivalves moving to shallow shorelines, early penguins & pinnipeds, shrinking forests, spreading grasslands and deserts, ungulate herbivorous grazers who diversified along with the grasses, and of course many other mammal groups as the Cenozoic is nicknamed the "Age of Mammals". These mammal groups that evolved in the Paleogene include bats, primates, even toed ungulates, odd toed ungulates, uranotheria, rodents, & large carnivores land predators like a 6 foot tall dog-hyena hybrid called Andrewsarcus and the first saber-tooth cats. Lastly, the birds whether flightless or flying were huge! One called diatrymas carried out the dinosaurs legacy as a huge flightless land predator, but thankfully those went extinct in the Eocene. ;)
