Short for Therizinosaurus, a dinosaur that pwns T-Rex. In the face. It's got two-foot-long claws like freakin scythes and a neck like a giraffe to spot prey. When it sees some other pussy dinosaur, it goes for the kill, hacking its victims to death and stabbing their soft, vulnerable throats with its vicious claws of doom.
OMG it's a therizino fighting a Tyrannosaurus!
