Therizinosaurus (Scythe lizard) lived 66 million years ago. Therizinosaurus or Therizinosaurus cheloniformis is a genus of very large theropod dinosaurs.

Therizinosaurus comprises the single species T. cheloniformis, which lived in the late Cretaceous Period, and was one of the last and largest representatives of its unique group, the Therizinosauria. The most distinctive feature of Therizinosaurus was the presence of gigantic claws on each of the three digits of their front limbs. These were common among Therizinosaurs but especially large in Therizinosaurus. The claws are the longest known from any animal. The claws were relatively straight, only gradually tapering into a point, as well as extremely narrow and transversely flattened.

A bizarre fossil discovery, especially of a 75-million-year-old dinosaur, can’t be fully understood without additional context. While Therizinosaurus or Therizinosaurus cheloniformis was finally tagged as some kind of theropod dinosaur in 1970, it wasn’t until the discovery of the closely related Segnosaurus and Erlikosaurus that it was finally identified as a “segnosaurid,” a bizarre family of theropods possessing long arms, gangly necks, pot bellies, and a taste for vegetation rather than meat.

The unusual arms and body anatomy (extrapolated after relatives) of Therizinosaurus have been cited as an example of convergent evolution with chalicotheriines and other primarily herbivorous mammals, suggesting similar feeding habits.

The elongated hand claws of Therizinosaurus or Therizinosaurus cheloniformis were more useful when pulling vegetation within reach rather than being used for active attack or defense because of their fragility, however, they may have had some role for intimidation. Its arms also were particularly resistant to stress, which suggests a robust use of these limbs.

Therizinosaurus was a very tall animal, likely having a reduced competition over the foliage in its habitat and outmatching predators like Tarbosaurus.

Additional fossil discoveries in the 1970s helped paleontologists to reconstruct this dinosaur as a 33-foot-long, five-ton, bipedal behemoth. As such, Therizinosaurus or or Therizinosaurus cheloniformis is the largest identified therizinosaur, and it weighed only a few tons less than the roughly contemporary Tyrannosaurus Rex.
