You should see one of these guys perform a Tombstone Pildriver with those tiny arms. Quite the spectacle!

Albertosaurus: a name so dignified and proper it almost sounds silly. Then you read its species name, sarcophagus, and things quickly get METAL!!! That’s sort of how the general population reacts to this dinosaur. Yeah, yeah, smaller cousin of T. rex, so it’s not as scary, kinda white bread, yada yada. Even a quick glance at the details, though, makes this animal look much scarier and more interesting. Come, face your fears and read on!
