BRSUG 22202: anterior portion of dentary symphysis including the first eight pairs of dentary alveoli. BRSUG 27379: fragment of a lower jaw including the posteriormost part of the symphysis and the anteriormost part of the divergent mandibular rami. BRSUG 27380: anterior part of a snout. BRSUG 27381: fragment of a left maxilla. BRSUG 27382: fragment of a right maxilla. BRSUG 27383: fragment of the posteriormost portion of the symphyseal part of a right dentary accompanied by the anteriormost portion of both splenials (medial to the last three preserved alveoli). BRSUG 27384: fragment of a right dentary. (Specimens BRSUG 27379 and BRSUG 27380 come from the same individual. The same is true for specimens BRSUG 27381, 27382, and 27383. Specimens BRSUG 27381 and 27382 come from the same part of the snout and their alveoli oppose the ones in the other side) | ||||||||||

BRSUG 27392: fragmentary skull with almost complete snout but lacking lower jaw. BRSUG 27393: fragmentary lower jaw (specimens BRSUG 27385, 27386 and 27387 very probably come from the same individual since they were found in association in the same place) | ||||||||||
