Genus GLOBIDENTOSUCHUS Scheyer, Aguilera, Delfino, Fortier, Carlini, Sánchez, Carrillo-Briceño, Quiroz and Sánchez-Villagra, 2013

The genus Globidentosuchus (type and only species G. brachyrostris ) was described recently by Scheyer et al. (2013) based on skull and lower jaw material from the Middle and Upper Members of the Urumaco Formation (holotype AMU-CURS-222; additional specimens AMU-CURS-223, -224, -301, -383 and -450). We here refer additional material, AMU-CURS-067 ( Figures 8 , 9 ), to this taxon.

Figures

FIGURE 8. Photographs of Globidentosuchus brachyrostris (AMU-CURS-067). 1-3, left ramus of lower jaw in lateral (1), medial (2), and dorsal (3) view. 4-6, anterior, portion of right ramus in lateral (4), medial (5), and dorsal (6) view. 7, 8, fragment of a (right?) maxilla in ventral (7) and lateral (8) view. 9, 10, Fragment of a (left?) premaxilla in ventral (9) and dorsal (10) view. 11, indeterminate cranial fragment found associated with the other skeletal element and therefore referred to the same specimen.

FIGURE 9. Photographs and interpretative drawings of Globidentosuchus brachyrostris lower jaw (AMU-CURS- 067). 1, 2, assembled right and left ramus in dorsal view showing posterior crushing dentition and the splenials participating in symphysis. 3, 4, posterior part of left ramus in lateral view. 5, 6, posterior part of left ramus in medial view. Note that fragment of articular is still partially present, articulating with the angular ventrally. Abbreviations: a, angular; ar, articular; co, coronoid; d, dentary; fic, foramen intermandibularis caudalis; fme; external mandibular fenestra; path, area of pathology; sa, surangular; sed, sediment; sp, splenial.
