Where can you find a dinosaur RPG?

They are all I know of

http://www.mydinos.com/ It's basicly a clubpenguin, Pokemon mix.

There is a site called JPLegacy.org/board with an RP called Live The Legend. It is a Jurassic Park RP, and there are also cenozoic, paleozoic, and other islands.

JPL has always been very active, and the RP is extremely high quality. Try there!
