>Do any one know where to find stygivenator skull parts pictures.

Yea, the Los Angeles Natural History Museum. I know that Thomas Carr and Tom Williamson will have a paper out soon redescribing the skull and I will have a new interpretation of the skull in the WAVP/SPS volume and that will be published soon.
>>If you have the Dinosauria, there is a picture of Aublysodon in it, the left one. That is the so-called skull of the Jordan theropod or Aublysodon molnari (=Stygivenator), it's just the front end of the snouth, with parts of the nasal and the maxilla. Not much has been published on it so it seems, but as it probably turns out to be, is that Aublysodon is probably a juvenile T.rex. If you don't have the book, I could scan the image for you...<<
Not quite. The type Aublysodon is from the Campanian and may or may not be different from all the other teeth that have been assigned to Aublysodon. Ford & Chure, Carr & Williamson, Currie, Holtz have all come to the conclusion that many if not all Aublysodon teeth are teeth of juveniles of known tyrannosaurs, not just T. rex. Stygivenator and Dinotyrannus are juveniles of T. rex. Some are Gorgosaurus, Daspletosaurus, etc. Each tooth and time period needs to be looked at.
