Alioramus

Alioramus is a genus of tyrannosaurid theropod dinosaur that lived during the Late Cretaceous Period, about 70-66 million years ago. It was a medium to large-sized carnivore, with an estimated length of about 26-33 feet and a weight of about 1-2 tons. Alioramus had a long, narrow skull with sharp teeth, and strong, muscular legs with large claws. Its body was probably covered in a layer of feathers, which may have been used for insulation, display, or both.

Alioramus was discovered in Mongolia in the 1970s, and was named by paleontologists in 1976. It is considered a relatively derived tyrannosaurid, and is thought to be closely related to other tyrannosaurids such as Tyrannosaurus and Tarbosaurus. Alioramus is known from a number of well-preserved fossil specimens, including several partial skeletons and skulls, which have helped paleontologists learn more about the anatomy and behavior of this dinosaur.
