The exhibited features of the studied skull: the parietal
and the adjacent bones, the narrow occipital, the temporal fossae that open partially to the parietal
and partially to the supraoccipital, the greater expansion of the posterior tuberosities, the weak temporal crests agree very well with those of the holotype BMNH 36677 of Bucapra and the female Proamphibos skull (Table I).
The dorsal edge of the jugal is joined to the postorbital and parietal.
Each postorbital articulates laterally with the dorsal edge of the jugal, medially with the caudolateral edge of the frontal, and caudally with the rostrolateral edge of the parietal.
The parietal articulates with the supraoccipital caudally, with the frontal rostromedially, and with the postorbital and the jugal rostrolaterally.
Although it was not possible to reconstruct the whole skull, the remaining bones (both frontals, reconstructed right parietal, reconstructed occipital) were complete enough to allow the identification of local compressive forces affecting the head.
Most of the right parietal and occipital could be recovered and restored.
Asymmetrically distributed on both sides of the fontanel, the lesion also extended back some millimeters over the coronal suture, onto the right parietal bone (the left parietal, almost completely destroyed, could not be examined).
The pale yellowish white parietal ring comprises the test of the head and lower jaw and is immaculate save for slight duskiness along the frontal and interparietal sutures.
The black nuchal ring, 8 middorsal scales long, begins just posterior to the parietal scale tips and passes just posterior to the supralabials.
The others each suffered from three distinct injuries: one had three on the frontal, while the other had two on the left parietal
and one on the right parietal
