Crocodyliformes indet.

EXAMINED MATERIAL. — FSAC BOUJ-355, fragment of a right dentary; 406, posterior fragment of left mandibular ramus.

DESCRIPTION

FSAC BOUJ-355 is a fragment of a left dentary ( Fig. 7I View FIG ). The best preserved alveolus is large and seems slightly compressed lateromedially. The lateral and medial margins of the dentary are parallel, suggesting that it was included in a long mandibular symphysis, and that the specimen was a longirostrine form. The alveolar margins are slightly offset, and the symphysis was slightly wider than high.

FSAC Bouj-406 is a posterior portion of a left dentary ( Fig. 7J View FIG ), and preserves four circular alveoli, probably the posteriormost. The portion is low in lateral view. It is not possible to determine if it can be related to the one of the species described above and below.
