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.
