Bernissartiidae indet.

( Figs 17E ; 19 A-C)

DESCRIPTION

Several mesiodistally elongate, bulbous and low-crowned isolated teeth have been recovered at Angeac-Charente ( Figs 17E ; 19 A-C) and their morphology is reminiscent of the tribodont condition described for the small neosuchian Bernissartia ( Buffetaut & Ford 1979; Martin et al. 2020). An incomplete left jugal (ANG15R-1205) is inflated on its lateral surface and might also belong to a bernissartiid. A small osteoderm (ANG16- 4907) also resemble the dorsal row of osteoderms figured by Buffetaut (1975) in Bernissartia fagesii . Here, the specimen is slightly wider than long although it is not as rectangular as in Bernissartia fagesii . A double-keel runs on its dorsal surface and an anterolateral process is present. The recently described bernissartiid Koumpiodontosuchus aprosdokiti ( Sweetman et al. 2015) also shares tribodont teeth with Bernissartia fagesii and, for this reason, we cannot yet ascertain a generic or specific attribution for the Angeac-Charente material.
