TYPE MATERIAL. — Lectotype, designated herein, is MNHN.F.A32407 (Faujas de Saint-Fond collection); Paralectotype is MNHN.F. R 65101 (Brongniart collection, ex Faujas de Saint-Fond collection).Note: Desmarest (1817) included in the type material some specimens illustrated by Knorr (1755): the one illustrated in pl. 15, fig. 2. is attributed to Eryon cuvieri and is a second paralectotype, which, however, is not among Knorr’s material that survived in the Naturhistorisches Museum Basel, Switzerland and thus seems to be lost ( Cleevely 1983). The other specimens (pl. 14, fig. 1; pl. 14a, fig. 1; pl. 14b, fig. 1) correspond to Cycleryon propinquus (von Schlotheim, 1822) .

TYPE LOCALITY. — Solnhofen (Bavaria, southern Germany). On the original inscription of the slab with the lectotype the locality is given as “Pappenheim” ( Fig. 1C ). However, the town of Pappenheim is located in the valley of the River Altmühl, 5 kilometres north of the outcrop area of the Solnhofen Lithographic Limestones. Probably, the specimen was purchased there from a local salesman. On account of the lithology of the slab there is no doubt that the specimen comes from the Solnhofen area.

TYPE AGE. — Late Jurassic (early Tithonian), see Schweigert (2007).

DIAGNOSIS. — As for the genus.

DESCRIPTION

See Garassino & Schweigert (2006).
