One new and the other old. A late cretaceous abelisaur from South America. There are actually skin impressions of the this animal so we have a good idea of what it actually looked like. Well, except for the color;)
This animal reached a length of 30 feet, and had one of the strangest heads on any theropod so far discovered. But the strangest thing would be the 4 fingered hands. Only 2 of which had claws. The fore arm bones have been greatly reduced to be virtully non existant.
