F-raptor is one from the original game. Like the original game it only works with Japanese vivosaurs for the team skill. And by that I mean dinosaurs that have Japan as the location found in ones Fossilary. Unfortunately it has to be paired with two specific Japanese vivosaurs: Futabi and Mihu.
A word of warning though. If Futabi is super evolved by a gold fossil you will lose the team skill.

I've found that the best method is, except for things like the Japanese-only vivosaurs and, to an extent, the boneysaurs, it's best to goof around until you figure out what works and what doesn't. I gave up trying to use things like Era and Diet a long time ago. XP (There's also the Japanese wiki with the actual 31 or so compatibility groups. We should probably bring that over at some point.)
