Therizinosaurus was a genus of the Therizinosaurid family. The T. cheloniformis species measuring perhaps 40 ft long and 22 ft high.

It's appearance has been a debate until recent decades.During the early phases of its discovery, it was assumed it was a species of a aquatic turtle. After several examinations and revisions, it was given the description of a gigantic carnosaur that measured 55 ft in length. After the discovery of related species Nothronychus, the debate over its appearance ended . It is uncertain what it ate, though, scientists agree that it was not an exclusive carnivore. The theories are it was a insectivore, herbivore, or even an omnivore.

Dinosaur researchers Florence and Charlie Magovern discovered two 18-inch-long fossilized eggs in the Xixia Basin in Nanyang, China. These are perhaps the largest eggs of any animal ever found. Painstaking study of one egg throughout 1995 by the Magoverns and others revealed the bones of a tiny theropod, possibly a therizinosaur, an herbivore about which little is known. The fossil baby was names "Baby Louie" after photographer Louie Psihoyes.[1]
