Allosaurus

Saurophaganax maximus was thought to be a very large predatory theropod that lived in the famous Morrison Formation of Jurassic North America. Several of the bones assigned to this genus were very similar to, but significantly larger than, those of Allosaurus specimens which had already been found in the Morrison, while others were unusual for those of a theropod at all, especially some of the vertebrae.

 

It's been a while since I did a dinosaur post around here, and if we're going to get back into the groove, let's get serious.
