15: Jaekelopterus - This Devonian age euryptyrid is still one of my favorite animals, and is in fact one of my favorite arthropods.
14: Tiktaalik - As a lungfish type creature, it was likely cute. Also, it was the first fish to crawl on land.
13: Arthropleura - The largest land arthropod. A beauty. The animal really should be in a JP movie, but I don’t know how it would realistically be implemented considering its need for high oxygen levels.
12: Hyneria - I like this fish. It is a rather interesting example of lobe finned fish as it was an active predator.
11: Woolly mammoth - It will likely become a modern animal in less than a decade. It was a staple diet for early H. sapiens and is an interesting example of a pachyderm.
10: Megalania - This animal used to have its own genus but was since moved to the genus Varanus. I find this animal as interesting as the American alligators. I drew as many of these as I drew cryolophosaurus.
9: Smilodon - This animal had 3 species, but fatalis was my favorite. I love their appearance. I have been to an area they have likely used to live in. I personally wished that they wouldn’t die after the ice age.
8: Meganeura - As I love dragonflies, this was inevitable. It is actually one of the few Carboniferous arthropods I can realistically see in the holocene.
7: Edaphosaurus - Edaphosaurus was a genus of animals distantly related to mammals. Some mistake the animal for dimetrodon, which is often mistaken for a dinosaur.
6: Thrinaxodon - This was a direct ancestor to mammals and was in multiple documentaries.
5: Atractosteus africanus - It’s a prehistoric alligator gar. What’s not to like?
4: Arctodus - I have seen bears in person yesterday and now I love em’.
3: Lycaenops - I like gorgonopsids, and this one is my favorite. I think it was in a few shows and documentaries.
2: Dimetrodon - I like this unique genus and its diversity. It varied in size. I like its appearance in walking with monsters.
1 Diplocaulus - My favorite extinct animal, Diplocaulus is my favorite as it is a salamander thing, and I love salamanders.
