Acrocanthosaurus

Information
Acrocanthosaurus atokensis is a species of carcharodontosaurid theropod dinosaur in the genus Acrocanthosaurus that lived approximately 115-110 million years ago in the Early Cretaceous. Acrocanthosaurus is known from multiple specimens of partial remains, often being found in the U.S. states of Oklahoma, Texas, and Wyoming, although teeth applied to the dinosaur have been found as far east as Maryland. This eleven-meter (38 foot) long carnivore is best known for the high neural spines that grew on its back, which are believed to have been used for muscle support or for display.

Design
Acrocanthosaurus atokensis is depicted with orangish-brown fur with a white underbelly. It is similar in design to Concavenator corcovarus and is even shown with a split sail akin to Concavenator's. However, the crest on Acrocanthosaurus is blue rather than red.
