Genus Taouzites Korn, 2001

Type species

Pharciceras taouzensis Termier & Termier, 1950 (original designation).

Diagnosis

Genus of the family Taouzitidae with extremely discoidal, involute conch; venter acute in the adult stage. With single ventrolateral grooves in the juvenile and pre-adult stage. Suture line with wide external lobe, high median saddle, lanceolate E 2 lobe, V-shaped lateral lobe and acute or rounded umbilical lobes. Suture line formula formula (E 2 E 1 E 2) L U 2 U 4 U 6 U 8: U 7 U 5 U 3 U 1 I.

Included species

Remarks

Taouzites presents the morphological end member of an evolutionary series in the Givetian, which, starting from simple gephuroceratids, is characterised by a flattening of the conch with a sharpening venter and simultaneous proliferation of the umbilical lobes ( Korn 2001).
