FMNH PR308 is an extinct, possibly unnamed, genus of tyrannosaurid dinosaur that lived in Alberta during the Late Cretaceous.
History[]
Brown (1914) collected a near-complete skeleton and skull, with the American Museum of Natural History selling it to the Field Museum of Natural History 40 years later. In Chicago, it was mounted as Albertosaurus libratus for a long time, with many parts of the skull found to be modelled from plaster, including most of the teeth. Thomas Carr (1999) reassigned the specimen to Daspletosaurus torosus.
Description[]
Experts are currently debating if the FMNH PR308 specimen is Daspletosaurus, or a new genus. It was labelled as Gorgosaurus and is on display in the Dinosaur Park museum, with academic and unofficial rumours spreading, stating it may be a new species or genus. In scientific literature, many classify FMNH PR308 as the "Dinosaur Park taxon" or the "Dinosaur Park tyrannosaurid". Teratophoneus differs from Alioramus, Gorgosaurus, Albertosaurus, Daspletosaurus, the Two Medicine taxon and FMNH PR308 by having a surangular shelf that overhangs the surangular foramen ventrolaterally. There may be an unprepared chunk of matrix on the pelvis of the mount.
Notable Specimens[]
- FMNH PR308 "Gorgeous George": A single specimen of tyrannosauroid. The specimen may represent a new genus, or one already known. Most sources classify it as a species of Daspletosaurus, possibly D. wilsoni (if it is not merely a sister taxon)[1]. The skull of the mount is based on a Daspletosaurus (previously Gorgosaurus and Albertosaurus) specimen known as Gorgeous George, a partial skull with few teeth.
