Albertosaurinae

Albertosaurinae is a subfamily of tyrannosaurid theropods comprising †Albertosaurus and †Gorgosaurus — two closely related Late Cretaceous apex predators from western North America. Distinguished from tyrannosaurines by their more slender proportions and longer, lower skulls, albertosaurines were the dominant carnivores of northern Laramidia roughly 76-70 million years ago.

Diet & Feeding

Carnivore

Albertosaurinae was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Late Mesozoic Era

Albertosaurinae lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
