Cyanolophorex

Cyanolophorex it a large tyrannosaurid. They may have preyed upon Lurduplocedromeus. Only 5 specimens have been found. Cyanolophorex looks very much like tyrannosaurus, except it is larger. They have a special blood groves and reinforced skulls, so Cyanolophorex can do strong 5 ton bite and bleed out prey. They lived 77.9-66 mya with Lurduplocedromeus and maybe Traumatonyx, but time range might change that.
