( 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.
