[7], In 2010 however, the North American paleontologist Lindsay E. Zanno in her large taxonomic reevaluation of Therizinosauria considered the referral of MPC-D 100/45 to Therizinosaurus to be likely based on the rationale that it was collected in the same stratigraphic context (Nemegt Formation) as the holotype, and shared the robust and four-toed morphology of other therizinosaurids such as Segnosaurus. This specimen was labelled is MPC-D 100/15 and consists of both left and right arms including the scapulocoracoids, both humeri (upper arm bones), right ulna with radius and left ulna, two right carpals, the right metacarpus including a complete digit Il, and some ribs with gastralia (belly ribs). Despite it’s terrifying appearance, this potentially feathered pot bellied beast is believed to have been an herbivore. In Real Life. Lautenschlager could neither confirm nor disregard that the hand claws could have been used for defense, intraspecific competition, stabilization by grasping tree trunks during high browsing, sexual dimorphism, or gripping mates during mating given the lack of more specimens. This awesome claw, measuring 22 inches long, is an exact replica of the giant claw possessed by Therizinosaurus. The upper end is flattened in a lateral direction, very wide and the distal end is highly robust. In 1972, another fragmented ungual (specimen MPC-D 100/16) was discovered at the Upper White Beds of the Hermiin Tsav locality, only preserving its lower portion. In this new monograph, he pointed out that the rib fragments in MPC-D 100/15 were more slender than the ones from the holotype, and identified MPC-D 100/16 and 100/17 as pertaining to digits I and III, respectively. It could grow up to 10 meters (33 feet) long and reach 5 tonnes in weight. The Therizino Claws can be found on a dead Therizinosaur by looking in its inventory before harvesting it for meat and hide or in a bag left on the ground if harvested before accessing the inventory or when eaten by other predators. [18], The humerus is robustly built, measuring 76 cm (760 mm) long. Cladogram below shows the placement of Therizinosaurus within Therizinosauria according to Hartman and colleagues in 2019:[31], In 2012, Stephan Lautenschlager and colleagues analyzed the complete endocranial anatomy of Erlikosaurus and other therizinosaurs that preserve braincases. The upper articular facets are very symmetrical and preserve a crest that is particularly taller in the first phalanx. This rare dinosaur lived during the Cretaceous period. [22] He maintained his position in 1988 by placing the Segnosauria into the now obsolete Phytodinosauria, and was one of the first to suggest a segnosaur assignment for the enigmatic Therizinosaurus. En 1998, cinq spécimens d'un dinosaure jusqu'alors inconnu, furent découverts en Mongolie. Though fossorial behaviour has been reported in several dinosaur species, the large body size largely rules out the possibility of burrow digging in therizinosaurs. This late Cretaceous period maniraptoran is most commonly recognized for its unusual claws which could measure over three feet and were found on each of it’s forelimbs. The size of the unguals MPC-D 100/16 and 100/17 may indicate that they belong to manual digits I and III, respectively. The upper articulation is configured into three parts. Therizinosaurus had mostly greenish scales, but it also had a cre… The expeditions unearthed numerous dinosaur and turtle fossil remains from the stratotype locality Nemegt (also known as Nemegt Valley), but the most notable elements collected were three partial manual unguals (claw bones) of considerable size. It is a coelurosaur theropod that lived around the late Cretaceous Period, and is the only one of its kind in the mod. Therizinosaur, group of theropod dinosaurs that lived during the Late Cretaceous (roughly 100 million to 66 million years ago) in Asia and North America and were characterized by their relatively small skulls, leaf-shaped teeth, and extended fingers with extremely long and robust claws. Nevertheless, an overall digging action would have been done with the foot claws because, since as in other maniraptorans, feathers on the arms would have interfered with this function.
