Therizinosaurus

Pronunciation: ther-uh-ZEE-noh-SAWR-us

Therizinosaurus cheloniformis

“turtle-formed reaping lizard”

Like a dinosaur version of Freddy Krueger, Therizinosaurus had the longest claws ever recorded on any animal, reaching up to three feet. But unlike Freddy, its claws were not just used as weapons.

In addition to self-defense, Therizinosaurus used its claws when eating to grab and pull leaves and fruit, and possibly to dig for tubers and roots.
