I've seen this movie before (on SyFy, where it originated!) and I believe there's a Carnotaurus in it. Short snout, tiny arms, big horns above the eyes? Anyone? I didn't watch it this time for two reasons:
1) I remember groaning a lot the first time; and
2) I promised my paleo-friends up here that we'd watch it as a group. They've been busy. :-(
But I remember that my favorite scene was when the Marines were shooting a couple of raptors (who were just standing there) and little 2D bood splatter effects were happening, but the raptors weren't budging or recoiling in any way. Then they just died. Like their HP suddenly hit "000" and their death animation was triggered. Awful, awful, awful.
