A new dinosaur species found in southern Utah has been identified, a fearsome looking creature that ate only plants, researchers say. Lindsay Zanno, a paleontologist at the Field Museum in Chicago, and her colleagues described Nothronychus graffami in a paper published Tuesday in Proceedings of the Royal Society B: Biological Sciences, the Chicago Sun-Times reported. The species is related to the velociraptor, the carnivorous dinosaurs made famous by the book and movie Jurassic Park, and to...

Segnosaurus, meaning "slow lizard," is a genus of therizinosaurid theropod dinosaur from the Cenomanian to Turonian stages of the Late Cretaceous Period. The type species, S. galinensis, was described in 1979 by Dr. A. Perle. It is known from three specimens consisting of a mandible, pelvis, hind limb, partial forelimb and vertebrae, as well as other fragments. The specimens were recovered from the Bayan Shireh Formation of the Mongolian People's Republic. Segnosaurus can be distinguished...

Suzhousaurus is a genus of therizinosaurid dinosaur from the Early Cretaceous Period. It was discovered in the Xinminpu Group of the Yujingzi Basin, Gansu, China. It was described by Li et al., who performed a cladistic analysis and found that Suzhousaurus is more derived than Beipiaosaurus and Falcarius, less derived than Alxasaurus and true therizinosaurids, and a relative of Nothronychus. Suzhousaurus is one of the largest known Early Cretaceous therizinosaurids, along with...

Nothronychus, meaning "slothful claw", is a genus of dinosaur from the mid-Turonian age of the Late Cretaceous Period (91 million years ago). It was discovered in the Moreno Hill Formation in the Zuni Basin, on the border of New Mexico and Arizona. The type species, N. mckinleyi, was described in 2001. A second species, N. graffami, was discovered in the Tropic Shale Formation of Utah. This specimen dated back about a million years before the nominate species. Nothronychus had a toothless...

Nanshiungosaurus is a genus of dinosaur from the Late Cretaceous Period that lived in what is now China. There are two known species: N. brevispinus was discovered in the Yuanpu Formation and N. bohlini was discovered from the Xinminbao Group. Only partial remains have been found which do not include the skull, tail, ribs or limbs. Analysis of this genus is based on the vertebrae and pelvis alone. At first, this dinosaur was thought to be a strange type of sauropod, but with the...

Falcarius, meaning "sickle cutter", is a genus of dinosaur from the Early Cretaceous Period (130 to 125 mya). This therizinosaurid dinosaur was the first of its kind to be found in North America. The fossils were found in east-central Utah, USA in 2005. Based on fossils recovered from another closely related specimen in China, scientists may clarify this specimen's relationship to the larger family of theropod dinosaurs. The site of discovery, Cedar Mountain Formation, was only a 2 acre plot....
