DESCRIPTION
Several isolated dromaeosaurid teeth, including the two reported here (ANG M-61; ANG M-45), were recovered following sampling and screening-washing of a gravel lens, rich in lignite and fossil bone remains ( Fig. 28 View FIG E-G). These teeth lack a serrated mesial carina, as in Tsaagan mangas ( Norell et al. 2006) and some teeth of Nuthetes destructor ( Milner 2002) . ANG M-61 is a complete tooth crown, and is more rounded. It is strongly recurved and its distal carina runs along half the length of the lingual face of the crown ( Fig. 28G View FIG ). There are 32 denticles per 5 mm on distal carina. This tooth is identified as a mesial tooth. ANG M-45 is the apical part of a second tooth ( Fig. 28 View FIG E-F). Its crown is more labiolingually compressed, and this tooth is identified as a lateral tooth. The distal carina bears numerous distinct denticles. In both teeth, the enamel surface is devoid of ornamentation.
Teeth identical in every way to those of Angeac-Charente have also been reported from the Berriasian of Cherves-de-Cognac ( Pouech 2008) and from the Tithonian of Chassiron ( Vullo et al. 2014). All these teeth from Charente are similar to those of the dromaeosaurid Nuthetes destructor from the Purbeck Group of southern England ( Milner 2002), and are tentatively referred to this genus.
