Description
In Adocus linealotus (CMM 60-15), the cranium experienced dorsoventral crushing in the snout region of the skull: both prefrontal are broken at the dorsal end of the bar that separates the orbit from the external naris. Additionally, the left jugal is broken at the posterior end of the orbit (see also Gaffney & Meylan 1989). We digitally separated the snout part (consisting of the left jugal, left maxilla, partial left prefrontal, both premaxillae, partial right prefrontal, and right maxilla) along the fractures from the rest of the cranium into separate models. Both models were then imported as PLY files into Blender, and the snout region was re-articulated with the remainder of the cranium. Additionally, within the braincase, the ventral process of the left supraoccipital was broken off the remainder of the supraoccipital (which is preserved in articulation). The ventral process of the supraoccipital houses the common crus area of the endosseous labyrinth, and therefore the supraoccipital breakage affected the endosseous labyrinth model. To reconstruct the endosseous labyrinth, we produced two separate models in Mimics, for the prootic-opisthotic part of the labyrinth, and the supraoccipital part, respectively. We imported both models into Blender, and digitally re-articulated. Cranial and labyrinth reconstructions had to be performed in the same Blender file to preserve the geometric relationships between labyrinth and cranium.
