Some days ago I made a thread on Pleistocene crocs in honor of Prehistoric Planet: Ice Age, and now I'm bringing it here too.
Let me prefice this by saying that I of course understand their absence, obviously more unique fauna takes priority and I don't begrudge the team their choice

Happy 120 anniversary to the prized fighter of antiquity, the absolute warlord of the Earth, one of the world's most powerful predators, an incredibly awesome animal, Tyrant King of all Saurians, and my 2nd favorite dinosaur, Tyrannosaurus rex 🦖 🎂

What a fantastic creature...

Postschizotherium intermedium, a large Pliohyracids with a hippo-like head. For almost a hundred year, people can only learn about this animal through its skulls and teeth. With no any thing about the postcranial, it's very hard to accurately reconstruct the entire body shape. 1/

A huge Dunkleosteus terrelli hurls towards a group of ammonites looking for lunch. One of them releases a cloud of ink trying to escape. All this happens while a school of Stethacanthus (a shark-like chondrichthyan) swims by in the Late Devonian sea.
