The oldest bear dogs lived during the mid-Eocene and probably looked something like Gustafsonia, which carries the hallmarks of a small, forest-dwelling generalist. Gustafsonia was found in Texas, pointing to a North American origin for Amphicyonidae.

Felt the urge to show appreciation to yet another group of Afrotherians, the Sirenians (dugongs and manatees) . This time I present to you the earliest member of Sirenia, meet Prorastomus from the Early Eocene of Jamaica. Sirenian evolution is quite interesting

Since Hyraxes are very awesome. I present to you yet another extinct Pliohyracid. Meet Antilohyrax, a hyrax from the Late Eocene of Fayum, Egypt. A hyrax that resembled a gazelle, had tusks and a low metabolism for an animal its size. It was a cursorial browser.

Maybe some of the extinct animals of Spec? Like the Eocene spinosaurid (I guess that could be another type of dinosaur).

I'm in whale mode right now for research, so gonna share one of my favorites for Remingtonocetus. Sounds very proper, I would absolutely have tea with Remingtonocetus (named for Remington Kellogg). It's a freshwater or coastal, early whale from the Middle Eocene.

The primates in PALEOCENE aren't based on a known fossil species, but are hypothetical ancestors of tarsiers and monkeys. They'd be similar to this Archicebus (illustration by Mat Severson, CC-BY-SA 4.0 license).
