Allos have two fingers and Rexys have 3.

Their both apex predators and therapods and were lean machines of their day.

Spinosaurus is the largest ever discovered one and the one with the most arguments over its appearance, for example its now thought that the sail was a hump. If so Spino was really big and bulky.

Bare in mind, birds are dinosaurs here also...
