Archovember 2024 Day 3 - Gorgosaurus libratus

The apex predator of Western North America during the Late Cretaceous was Gorgosaurus libratus. Found so far in Alberta, Canada and Montana, USA, it lived several million years before Tyrannosaurus rex would appear. While it was a tyrannosaurid, it was more closely related to Albertosaurus, so much so that some scientists consider it to be another species of Albertosaurus. Gorgosaurus is the most numerous tyrannosaurid in the fossil record, known from dozens of specimens. This abundance of fossils has allowed paleontologists to investigate Gorgosaurus’ ontogeny, life history and many other aspects of its biology. For example, in 2023, a 5-7 year old juvenile Gorgosaurus was discovered with stomach contents consisting of two intact Citipes juveniles about a year old. This showed that younger Gorgosaurus’ were mostly eating prey much smaller than them, and were probably not hunting in packs, as the meal would not have been large enough to share. That being said, only the remains of the hindlimbs and caudal vertebrae of the juvenile Citipes were present, suggesting that this Gorgosaurus may have had a preference for the muscular hindlimbs. Many Gorgosaurus specimens also preserve evidence of facial scars, a result of intraspecies facebiting.

Gorgosaurus would have lived on the coastal plain along the western edge of the Western Interior Seaway, an inland sea which divided North America in half during the Late Cretaceous. The area was subtropical with periods of drought. Conifers would have dominated the forests, while the underbrush consisted of ferns, tree ferns and angiosperms. Gorgosaurus is best known from the Dinosaur Park Formation. Here, it would have lived alongside another apex predator: Daspletosaurus wilsoni. While these tyrannosaurids were roughly the same size, they may have preferred different types of prey, allowing them to coexist without too much competition. And there was a wide diversity of prey here, from many of the most famous ornithopods like Parasaurolophus walkeri, Corythosaurus casuarius, Gryposaurus notabilis, and Lambeosaurus lambei, to beloved ceratopsians like Styracosaurus albertensis, Centrosaurus apertus, Chasmosaurus belli, Spinops sternbergorum, and Vagaceratops irvinensis. There were also ankylosaurs like Anodontosaurus inceptus, Dyoplosaurus acutosquameus, Edmontonia rugosidens, Euoplocephalus tutus, Panoplosaurus mirus, Platypelta coombsi, and Scolosaurus. Pachycephalosaurids included Foraminacephale and Stegoceras validum. Gorgosaurus also shared space with other, smaller theropods, like the ornithomimids Ornithomimus and Rativates, caenagnathids like Caenagnathus, Chirostenotes, and Citipes, dromaeosaurids like Dromaeosaurus and Saurornitholestes, and troodontids like Latenivenatrix and Stenonychosaurus. Dinosaurs were not the only animals here, and Gorgosaurus would have also had to share space with the giant azhdarchid pterosaur Cryodrakon, as well as alligatoroids like Albertochampsa and Leidyosuchus, and choristoderes like Champsosaurus. Gorgosaurus is also known from the Two Medicine Formation and Judith River Formation.

[mesozoicmarket]

A dinosaur tooth of an indeterminate tyrannosaurid, either Daspletosaurus sp. or Gorgosaurus libratus from the Judith River Formation in Hill County, Montana, United States. Unfortunately, the vast majority of teeth of Gorgosaurus and Daspletosaurus are indistinguishable from one another. There are currently two species of Daspletosaurus described from this deposit, Daspletosaurus torosus and Daspletosaurus wilsoni. The tooth has an interesting red coloration and pronounced enamel texture. The midline distal serration density is 13/5mm, while the midline mesial serration density appears to be the same, though very worn down, and around 15/5mm towards the base.

Daspletosaurus wilsoni. I think I made the head too small unfortunately :(

Re-analysis of a dataset refutes claims of anagenesis within Tyrannosaurus-line tyrannosaurines (Theropoda, Tyrannosauridae)

Published 28th November 2023

Phylogenetic reanalysis of Daspletosaurus wilsoni reveals a cladogenetic Tyrannosaurinae composed of four morphologically and biogeographically distinct clades that are formally defined and diagnosed (Teratophoneini clade and Tyrannosaurini).

New tyrannosaur fossil discovered may be a “missing link”

New tyrannosaur fossil discovered may be a “missing link”

Though Tyrannosaurus rex is considered the “king” of the dinosaurs, the “tyrant lizard” only roamed Earth for about the last two million years of the 150-million-year “Age of Dinosaurs”. Now, researchers believe they have found a missing piece of the tyrannosaur lineage. Daspletosaurus wilsoni roamed approximately 76.5 million years ago – 10 million years before […]

Daspletosaurus wilsoni!!!!!!!!!!!!!!

AHHHH THEY PUBLISHED THE NEW DASPLETOSAURUS SPECIES I GOT TO SEE THE TYPE SPECIMEN OF WHEN I WAS DRIVING THROUGH MONTANA

[new-dinosaurs]

Daspletosaurus wilsoni Warshaw & Fowler, 2022 (new species)

(Maxilla [bone in the upper jaw, top] and reconstructed skull [bottom] of Daspletosaurus wilsoni, with preserved bones in white, from Warshaw and Fowler, 2022)

Meaning of name: wilsoni = for John Wilson [discoverer of the original fossil]

Age: Late Cretaceous (Campanian), probably around 76.5 million years ago

Where found: Judith River Formation, Montana, U.S.A.

How much is known: Partial skeleton of one individual, including a partial skull, some vertebrae, and a foot bone.

Notes: D. wilsoni was a tyrannosaurid theropod, making it a fairly close relative to Tyrannosaurus. Two other species of Daspletosaurus have previously been named, the slightly older D. torosus and the slightly younger D. horneri. D. wilsoni exhibits a mixture of traits seen in the other two species. Combined with its intermediate geologic age, the describers of D. wilsoni suggest that the three named species of Daspletosaurus formed a direct line of descent, with D. wilsoni having descended from D. torosus and given rise to D. horneri.
