So, what your favorite in God’s creation that is either alive presently or is extinct? It can be one or both.
I’ll start with the Tamisiocaris, in fact if I wanted to I would put all the critters of the Cambrian Era in the list due to how wacky and wierd and alien they are. But the Tamisiocaris just seems like a giant alien shrimp that would try and suck off my face.
The animal that is still alive today is the seal, and not any seal in particular, just all of them I loves seals due to how chubby and cute they are and how silly they are when they interact with humans and each other.
