NOW THIS IS A SPINO! I really love the design! I don't understand why people argue that Spinosaurus had a HUMP not SAIL OF COURSE IT HAD A SAIL IT WAS CROCODILIAN If it had a hump, it wouldn't be able to swim as fast or efficiently. (Sorry for ranting here XP)
Well, I guess you're right, it's not really a sail, but it's not a hump either. And I know they don't have a knot, but you can notice how crocodillian they are. They have the same basic type of skull design (I don't mean the skull is the same, just similar enough) The same type of long, straight teeth, and the same sensor pores at the tip of the snout.
That's an amazing animation, but I don't understand why the theropod pose has gone from upright (incorrect as hell ), to horizontal (correct?), to - basically turning downwards? They look like they're gonna fall on their faces.
The larger dinosaurs are posed liked this in Primal Carnage because their targets are humans, and because the camera partially controls the pose of the chest. If the chest was angled up slightly it would bend downwards because the player usually looks down at a 30ish degree angle to see the humans.
