If this is the confirmed list: http://fossils-archeology.wikia.com/wiki/User_blog:Adsper/All_Possible_Mobs

Then it's got a lot already. Part of me wants to see anomalocaris but frankly I don't imagine they'd provide much in the way of new gameplay opportunities.

So I'd have to say megatherium

...though cave bears and andrewsarchus are nearly as tempting. Troodon is an excellent choice.
