The specimen is identified as a dyrosaurid based on the presence of otic capsules that closely approach one another medially, and an occipital exposure of the parietal. Although the lateral margins of the supratemporal fenestrae are not preserved, they can be confidently reconstructed as rostrocaudally elongate, based on the size of the preserved supraoccipital (fig. 6B). In addition, the supraoccipital contributes to the bases of occipital tuberosities, although their full extent is not known.</paragraph>
