Dinosaur Park Formation, including two complete skulls of Gorgosaurus and an isolated postorbital of Daspletosaurus , reveals new information on the anatomy and ontogeny of tyrannosaurids.
Albertosaurus and Gorgosaurus share proportionally longer and lower skulls than Daspletosaurus and other tyrannosaurids. The end of the snout was blunt, and the nasal and parietal bones were fused along the midline of the skull, as in all other members of the family.
Here, we describe two small, articulated Gorgosaurus specimens (skull lengths of ca. 500 mm) that help advance our knowledge of the anatomy and ontogeny of this taxon and of tyrannosaurids in...
11 lut 2022 · Thus, the long and gracile skull shape of Qianzhousaurus (and Alioramus) manifests itself in the posterior part of the lower jaw, despite the fact that the posterior part of the upper skull (jugal, postorbital, quadratojugal, squamosal) is not elongated anteroposteriorly.

12 mar 2014 · The specimen, DMNH 21461, consists of three separate pieces of a skull found in very close proximity to one another, including part of the right maxilla, a section of skull roof and braincase, and the rostral part of the left dentary.
Here, we describe a remarkable specimen of a juvenile Gorgosaurus libratus that preserves the articulated hindlimbs of two yearling caenagnathid dinosaurs inside its abdominal cavity. The prey were selectively dismembered and consumed in two separate feeding events.
