Carnotaurus

Short stubby arms, short stubby horns. Carnotaurus, was definitely an odd looking theropod. The forearms were even shorter than Tyrannosaurus rex - in fact they were so short that the hands appeared to be sprouting from the upper arm bone, the humerus!

A slender, shallow lower jaw contrasted with the heavy, robust-looking skull while a pair of thick horns jutted from the skull above the small, forward facing eyes. It is theorized that Carnotaurus was capable of hatchet-like attacks with its head and horns; a skull would not have survived in a head-butting contest.
