MATERIAL EXAMINED. — Ilium: 1; femur: 2.

DESCRIPTION

A tiny left ilium is characterized by a robust ilial shaft devoid of crista dorsalis, an elongated tuber superior with a relatively flattened, wide, dorsal edge, a wellmarked preacetabular fossa, a uniformly thickened area for the suture with the ischium.

The best preserved femur is relatively robust in general appearance and presents a sharp, distinctly undivided crista femoris.

DISCUSSION

The morphology of the ilium and the femora is congruent with that of the B. viridis group ( Böhme 1977; Sanchiz 1977; Bailon 1999). The only exception is the tuber superior of the ilium that is proportionally massive and does not bear the anterior tubercle typical of this species. Due to the fact that this tubercle is sometimes underdeveloped in the B. viridis group (Delfino pers. obs.) and taking into consideration the small size of the ilium from Capo Mannu D1 LF, these remains are here tentatively referred at species level to cf. Bufo gr. B. viridis .
