Valgipes bucklandi ( Lund, 1839)

( Figure 4.1-2 )

Referred material. MCL 4262, skull almost complete, hemimandible with a portion of the symphysis, with the mf1-2 and dermal ossicles; MCL 4264, partial skull, partial right hemimandible, left and right astragali, right tibia and fibula; MCL 4293, partial skull, partial right hemimandible that preserves only the mf3, several vertebrae, almost complete hand, right femur, right tibia and fibula, right and left astragali.

Description. In dorsal view, the parasagittal crests start at the nuchal crest and end at the level of the postorbital process of the frontal. In some specimens (MCL 4294 and MCL 4262), a little behind the fronto-parietal suture, the parasagittal crests differ in the form of "wedge" in the direction of the postorbital processes, with the presence of a sagittal crest on the middle line of the parietal ( Figure 4.1 ). In contrast, specimen MCL 4393 does not have the sagittal crest, and its parasagittal crests have the same morphology ( Figure 4.2 ).
