The topological organization of the turtle cranium is constrained and conserved over long evolutionary timescales

The Anatomical Record, Volume 307, Issue 8, Page 2713-2748, August 2024.
Abstract The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal fenestrae and loss of cranial joints (i.e., characteristics of anapsid, akinetic skulls). Evolution and ontogeny of the turtle cranium are associated with shape changes.
