Summary

Description
English: Skeleton reconstruction of the holotype of the therizinosaur Erlikosaurus andrewsi, MPC-D 100/111. It was unearthed from the Bayan Shireh Formation, at the Bayshin Tsav locality. The holotype is very fragmentary, consisting of:[1][2]

Complete skull, left humerus and right pes. Several cervical vertebrae fragments.

Although fragmentary, the skull of Erlikosaurus has been greatly useful as a reference for other therizinosaurs. The articulated skull has become the focus in many studies due to its exceptional preservation, such as bite force estimates[3], mouth opening[4], niche partitioning[5], and cerebral capacity.[6] The cervical vertebrae were not illustrated in the original descriptions, and the count is unknown, however, Perle claimed that they resemble those of the contemporary relative Segnosaurus.[2]

Español: Reconstrucción esquelética del especimen holotipo MPC-D 100/111 de los terizinosauridos Erlikosaurus andrewsi. Fue desenterrado de la Formación Bayan Shireh, en la localidad Bayshin Tsav. El holotipo es bastante fragmentado, consistiendo de:

Cráneo completo, humero izquierdo y pie derecho. Algunos fragmentos de vertebras cervicales.

Aunque fragmentado, el cráneo de Erlikosaurus ha sido enormemente útil como referencia para otros terizinosaurios. El cráneo articulado se ha convertido en el centro de atención de algunos estudios debido a su excepcional preservación, tales como estimaciones de fuerza de mordida, abertura de hocico, división de nichos y capacidades cerebrales. Las vertebras cervicales no fueron ilustradas en las descripciones originales, sin embargo, Perle aseguro que se parecen a las del cercano Segnosaurus.
