First thing that came to mind? Horror-survival setting, primarily with velociraptors and other hunters to worry about. Sure there'd be a mixup of other dinosaurs, but velociraptors terrify me as much as they are incredibly awesome. 

I'd not like to be trapped in any location/setting/area with arguably what is earth's history's greatest pack hunter. I would not feel safe with anyone or anything. You got a grenade launcher, flamethrower, automatic machine gun, ten-fifteen trained US Marines, a squad of French Foreign Legion guys, a fucking tank? Their pack(s) probably already took that into consideration. Show me enough velociraptors and were all screwed man. 

Fuck. Don't even get me started on deinonychus or achillobators. 

Hell, forget everything i've said. Dromaeosaurids in general are terrifying.

Edit: On second thought, i'm pretty sure velociraptors were more solitary hunters than pack hunters. I believe the deinonychus was a pack hunter, which is all the more terrifying. Hahah, velociraptors would be easier to deal with. The bigger dromaeosaurids, not so much.
