Irritator

This is Irritator.  They call him Irritator because when they found his bones, they thought it was a Pteranodon because someone had previously modified to look like a Pteranodon.  The scientists were irritated because they were tricked.  Irritator was and is basically a small Spinosaurus with a smaller spine.  It was 26 feet long.  It lived in the early Cretaceous and was a theropod.  It was found in Brazil, which is not very common at all.
