Material.— Kurgan: 23 teeth.
Description.—The teeth are rather robust. The main cusp is conical, rounded in the cross−section, basally inflated with a sharp apex. There are one or two pairs of cusplets. The labial face is slightly convex, the lingual one more so. The cutting edge is not sharp, displaced labially, so that the lingual face is visible in labial view. The enameloid is mainly smooth. There are distinct short enameloid folds on the base of the labial side, which originate a strongly waved border overhanging the root. The distal parts of the lingual face may be covered by fine, almost imperceptible flexuous striations. The root has a typical scyliorhinid shape. The basal face of the root is flat, the lingual side displaced occlusally and forms the prominent lingual protuberance. This is deeply divided by the nutritive groove which also transects the basal side of the root. The root of presumed anterior teeth forms well separated branches, prominent distally and basally in labial view, and less prominent in the lateral teeth.
Remarks.—Outside the Priabonian of the Trans−Urals, the teeth of a similar morphology are known from the English Ypresian (London Clay), where the species was described by Cappetta (1976). Ward (1980) noted F. pattersoni from the latest Ypresian to the early Bartonian (Barton Al−3). The teeth described by Case et al. 1996 (pl. 8: 144–147) as Galeorhinus sp. from the Eocene of Uzbekistan (“White Mountain Formation”), also belongs to F. pattersoni .
