description Therizinosaurus cheloniformis Overview

Therizinosaurus cheloniformis was a large therizinosaurid theropod that lived during the Late Cretaceous in what is now Mongolia. It is known from incomplete remains, especially enormous forelimb elements and elongated, strongly curved hand claws, some of the longest claws known among terrestrial animals. Although its skull is unknown, related therizinosaurs indicate that it was a feathered, long-necked herbivore or omnivore rather than a conventional predatory theropod.

What is Therizinosaurus cheloniformis most famous for?

This Late Cretaceous dinosaur is renowned for having the longest claws of any known animal, with some hand claws reaching up to three feet in length. It also possessed massive forelimbs that supported these gigantic, strongly curved structures.

Despite being a theropod, a group largely defined by carnivores like Tyrannosaurus rex, Therizinosaurus is believed to have been an herbivore. Its massive claws were likely used to strip vegetation from high branches or for defense against predators.

Where were the first fossils of Therizinosaurus found?

The incomplete remains of this bizarre dinosaur were first discovered in the Nemegt Formation of Mongolia. Early paleontologists originally misidentified its massive claws as the ribs of a giant turtle, which is why it was given the species name meaning "turtle-formed."

How big was Therizinosaurus?

Therizinosaurus was a massive animal, estimated to have grown up to 10 meters in length and potentially weighing up to five tons. It was one of the largest theropods of its environment, towering over many of its Late Cretaceous contemporaries.
