Evolution: life in the Priabonian Age (late Eocene, Cenozoic)

'Walking with Beasts' is a dramatization of life in the Cenozoic, focused mainly on the evolution of mammals. "Broadcast in 2001, it told the story of life on Earth from the death of the dinosaurs to the dawn of the age of man" (BBC, 20011). The second episode ('Whale Killer') is centered on the Priabonian Age. (See also Wikipedia, 20112.)

Time: Priabonian Age (36 million years ago), late Eocene Epoch, in the Cenozoic Era.
Setting: Tethys Sea, at the commencement of drastic changes in ocean currents and climate due to the freezing of the polar caps.
Main species featured in the episode:
  • Basilosaurus, an ancestral whale, a genus nowadays extinct.
  • Andrewsarchus, a carnivore mammal, a genus nowadays extinct.
  • Apidium, a primate, a genus nowadays extinct.
  • Moeritherium, a vegetarian mammal, a distant relative of elephants and sea cows, yet a genus nowadays extinct.
