Cranial ecomorphology of turtles and neck retraction as a possible trigger of ecological diversification. [PDF]
Evolution, 2022 Abstract Turtles have a highly modified body plan, including a rigid shell that constrains postcranial anatomy. Skull morphology and neck mobility may therefore be key to ecological specialization in turtles. However, the ecological signal of turtle skull morphologies has not been rigorously evaluated, leaving uncertainties about the roles of ...
