Another albertosaurine called "Gorgosaurus" may be a synonym of this genus but a different species?


Albertosaurus sarcophagus is a genus of albertosaurine tyrannosaurid theropod native to North America in the Middle Campanian stage of the Late Cretaceous epoch. It is known from a few scrappy remains and is a bit unknown. It was built like all theropods, it was bipedal (walking on two legs [from bi, meaning two and pedal, meaning locomotion]), had three long toes on its feet and had sharp teeth for eating meat (for the exception of therizinosaurians, oviraptorosaurs, ornithomimosaurs, some birds, some ceratosaurs and possibly some troodontids). It had a long tail to keep its balance and two short arms with three fingers (Tyrannosaurids are characterized by having two fingers but a recent discovery found a small third finger).[1]
