Gobiconodon hopsoni
Taxonomy
Gobiconodon hopsoni was named by Rougier et al. (2001). Its type specimen is PSS MAE 140, a maxilla (partial right maxilla preserving the last molariforms and fragments of the two preceding molariforms), and it is a 3D body fossil. Its type locality is Oshih, northern slopes of Arts Bogd, which is in a Valanginian/Neocomian terrestrial sandstone in the Oshih Formation of Mongolia.

Diagnosis
Reference | Diagnosis | |
---|---|---|
G. W. Rougier et al. 2001 | Large gobiconodontid with deep ectoflexus in a lingually positioned M5. Upper dental arcade forms a closer dental arch than in other species of Gobiconodon, with the last molariforms projecting medially more pronouncedly than in other species of Gobiconodon. Labial cingulum on the M5 broader than that of G. ostromi. Zygoma is deeper in G. hopsoni than in G. ostromi, and projects more posteriorly, closer to the alveolar margin. G. hopsoni is the largest species of Gobiconodon described so far (appendix 1). |
