A new carnivorous dinosaur belonging to the tyrannosaur family has been described by palaeontologists in a new journal article published online.
The Oldman Formation is a layer of rock dating back to the Late Cretaceous period that lies beneath much of modern-day Alberta, Canada, an area famous for its abundance of dinosaur fossils.
One such dinosaur was discovered in the area and excavated by palaeontologists at the University of Alberta in 2010/11. Now, the dinosaur, a tyrannosaurid, has been described at length in a new article published on October 2, 2026.
The dinosaur has been named Tromerosaurus
The article reveals that the dinosaur’s full latin name is Tromerosaurus solumons. “Tromerosaurus” means “frightful lizard”.
The dinosaur is an Albertosaurine, meaning it belongs to a lineage of tyrannosaurs that lived in the Late Cretaceous period. Albertosaurus is another in this lineage, while others like the T-Rex belong to the Tyrannosaurine lineage.
It has been discovered that this dinosaur co-existed in this area of prehistoric Alberta alongside another tyrannosaur known as Daspletosaurus torosus, which could be invaluable information to researchers investigating this genus.
It reportedly shares many features with the Daspletosaurus, and another dinosaur known as Gorgosaurus, but is made distinct by a longer front to back opening in the maxilla (upper jawbone), and a narrower bony ridge near the front of the maxilla.
