About
Albertosaurinae, anchored by Albertosaurus, is one of two groups within Tyrannosauridae. Members of Albertosaurinae are known as albertosaurines.

Typically, albertosaurines have proportionately longer shins, feet and toes, shorter and shallower skulls, and are more slender than the robust tyrannosaurines (members of Tyrannosaurinae — the other group of tyrannosaurids) and differ in features of the skull that you need a PhD to understand. No offence intended.

All albertosaurines hail from western North America with the oldest member—Gorgosaurus—in its pomp during the Campanian of the Late Cretaceous while the youngest—Albertosaurus—didn't quite make it to the end of the age of dinosaurs and was pushing up daisies a good million years before the close of the Maastrichtian.

Together with Tyrannosaurinae, the albertosaurines make up Tyrannosauridae.

Etymology
Albertosaurinae is derived from Albertosaurus (anchor of the group) and the Latin "inae" (subfamily), referring to its position within the family Tyrannosauridae. Albertosaurus was named for Alberta, Canada, and the Greek "sauros" (lizard).
