Stygivenator

Stygivenator

Stygivenator (meaning "Hell Creek hunter"), also known as the "Jordan theropod" is a dubious genus of tyrannosauroid dinosaur from the Hell Creek Formation, the type species is Stygivenator molnari. Originally considered a species of Aublysodon, another dubious genus, and then a juvenile of Tyrannosaurus, its specific identity can not presently be determined due to its poor preservation making it impossible to rule out an identity as either a specimen of Tyrannosaurus or Nanotyrannus
