Utahraptor - Was about the size of what JP depicts the velociraptors to be, and would add to the feathered variants.
Caudipteryx - Really small and bird-like. Maybe a bit bigger than compagnathus? Omnivorous (maybe). Might be a fun one that gets along with any dinosaur, even Therizinosaurus.
Megalodon - I know, I know. Not a dinosaur. And probably only as old as about 20 m years. But is there a rule that JP/JW animals have to all be Cretaceous or earlier? And its size puts Mososaurus in its place!
Oviraptor - Originally thought to be egg-stealers, their beaks suggest they might have been omnivorous. Could maybe be another interesting flightless bird to get along with Therizinosaurus?
