I came across a youtube channel a while back that discussed various on going sci-fi and fantasy universes such as Avatar, How to Train Your Dragon, Dr. Who, Jurassic Park/World, etc. There are a couple of videos on this channel discussing Avatar, some of the creatures on it as well as the possible evolutionary life of some of the animal life on the planet. I thought I would post their playlist here as well as an additional video (the Thanator vs. Tyrannosaurus Rex video they made that doesn't appear on their Avatar playlist).
I tried to post the playlist in video form, but I couldn't get that to work, so I posted the link to the playlist, the second video from the playlist and the video left off of it.
