Amiiformes indet.

(Figs 7 E-H; 8A-D)

DESCRIPTION

Amiiform fish are represented in the assemblage by isolated teeth, jaw remains (Fig. 7 E-H) and vertebrae. Most of the labiolingually compressed teeth show a typical triangular crown apex and bear two well-developed carinae (Fig. 8 A-C). Such teeth were previously referred to Caturus sp. (Sweetman et al. 2014; Vullo et al. 2014; Pouech et al. 2015), although this dental morphology is also present in more derived members of Amiiformes (i.e., Amiidae). Some tooth associations are interpreted as vomerine dentitions (Fig. 8D). These elements bear teeth of various sizes, subconical and devoid of carinae, as those found in many Amiiformes (Grande & Bemis 1998) . It is worth noting that this tooth morphology corresponds to that usually assigned to the aspidorhynchid Belonostomus (e.g., Sweetman et al. 2014; Pouech et al. 2015). However, the rounded morphology of the vomerine tooth plates from Angeac-Charente and the fact that they are paired elements preclude assignment to Belonostomus (in which the vomer is unpaired); therefore, all isolated small teeth with a conical crown devoid of carinae are here referred to Amiiformes indet.
