Quantitative assessment of the vertebral pneumaticity in an anhanguerid pterosaur using micro-CT scanning
Abstract Research on the postcranial skeletal pneumaticity in pterosaurs is common in the literature, but most studies present only qualitative assessments. When quantitative, they are done on isolated bones. Here, we estimate the Air Space Proportion (ASP) obtained from micro-CT scans of the sequen...
