I've been trying to see if the 3D models for an old CD-rom video game I've been looking at are actually in the game files or not (seen at 0:20 and 4:45 in the YouTube video)

I've so far managed to get into the files for it from an ISO on archive: https://archive.org/details/dinosaurcd 

but a lot of it is just in weird formats called ".ANM" I'm hoping the models are actually in the game. But I have no way of telling, if anyone could help with this that would great.

.anm means animation

What software could I use to open them?

there are only sprites and animations

What kind of animations? green screen renders?
