Nasal Capsule and Skull in Newborn Tupaia
Tupaia belangeri (27 MB)
This module shows the relationship between cranial base, facial skeleton, and cartilaginous nasal capsule in a newborn Tupaia. Tupaia, the tree shrew, is a sister taxon to Primates, and we use this animal to estimate the ancestral condition. Key perspectives in the module show how the cartilaginous posterior nasal cupula creates a framework around which intramembranous bone is shaped. In our collaborative work with Dr. Timothy Smith, Slippery Rock University, we have shown that early degradation of the posterior nasal cupula is associated with reduction in the midfacial skeleton.

| Varecia variegata (31 MB) | Cebuella pygmaea (32 MB) | Macaca nemestrina (55 MB) |
These modules highlighting comparative anatomy of the sphenoethmoid junction were produced in our collaborative work with Dr. Timothy Smith, Slippery Rock University. These modules are interactive 3D PDF files that allow visualization of the sphenoid in three perinatal primates: a strepsirrhine (Varecia variegata), a platyrrhine (Cebuella pygmaea), and a catarrhine (Macaca nemestrina).
