Dinosaurs: Therizinosaurus!

(This is really getting into the older stuff, before I was using good quality paper to paint on)

Therizinosaurus. A massive, clawed denizen of prehistoric times that wouldn’t eat you, but still might mess you up severely. It and its kin had the largest claws of any known animal in existence–two to three  feet in length– and the family name Therizinosaurs means “scythe lizard”or “reaping lizard”. This particular dinosaur currently only exists as an incomplete skeleton of  arm bones and giant claws. A lot of guesswork has gone into figuring out what it actually looked like but in 2010 Gregory S. Paul estimated the maximum size of Therizinosaurus at 33 feet in length and weighing five tons. It walked on four toes instead of three(my drawing above is goofed,as I found this out after drawing was completed), as most other theropods(bipedal dinosaurs) do.

Scientists have muddled over what Therizinosaurus and its relatives ate, but most are sure it was herbivorous. The gigantic claws are more suited for digging and possibly defense, not grappling and hanging onto struggling prey. A Tarbosaurus, one of the top predators of the day, might have turned away from a Therizinosaurus after getting a slash across the face, or at least been stalled long enough for a Therizinosaurus to escape. Plus, as more of Therizinosaurus’ close relatives’ fossil remains are found, more skulls and therefore more insight into their eating habits are falling into place.

Therizinosaurus was most likely covered in feathers, given that its close relative Beipiaosaurus was–fossil remains of Beipiaosaurus have retained complete imprints of coats of feathers.

The Therizinosaurs were native not only to Asia, but parts of North America as well. We had them here!
