Scelidotherium bravardi Lydekker, 1886

( Figure 3.1-2 )

Referred material. BM(NH)M 37626, skull almost complete; MMP 9-S, partial skull; MMP 31-S, skull and partial mandible; MMP 128-S, toothless skull; MMP 458-S, skull, mandible, left femur, right radius, patella; MMP 157-S, skull and mandible.

Description. The morphology observed is very similar to that of Scelidotherium leptocephalum , without the development of a sagittal crest. In some specimens, the parasagittal crests are parallel in all their extension (MMP 9-S, MMP 31-S, MMP 128-S, and MMP 157-S) ( Figure 3.1 ), while in others they show a rhomboidal outline at the level of the fronto-parietal suture [BM(NH)M 37626 and MMP 158-S] ( Figure 3.2 ).
