( Fig. 17 View FIG A-D)
DESCRIPTION
Small isolated teeth are commonly recovered from residues obtained from bulk screening. Many of them ( Fig. 17 View FIG A-D) are leaf-shaped, labiolingually compressed, low-crowned and pseudoziphodont, a characteristic of the posterior dentition in the atoposaurid genus Theriosuchus ( Schwarz & Salisbury 2005; Lauprasert et al. 2011; Martin et al. 2014b). Members of the genus Theriosuchus are small crocodyliforms with total body lengths less than 1m ( Schwarz & Salisbury 2005). Besides teeth, two skull bones might belong to this genus: a right jugal (ANG 16-5179) and a fragmentary frontal (ANG 14-3692). The jugal is about 1 cm long and its ornamented lateral surface is thin and projects ventrally. The frontal preserves the interorbital area and displays an acute median keel on its dorsal surface. A finely sculpted osteoderm, longer than wide and possessing a shallow median keel ( Fig.19D View FIG ), matches the morphology of dorsal osteoderms of the tail region in Theriosuchus pusillus ( Owen 1879; Clark 1986).
