The endocranial anatomy of the stem turtle Naomichelys speciosa from the Early Cretaceous of North America [PDF]
Acta Palaeontologica Polonica, 2019 Fossil turtles are one of the least studied clades in regard to endocranial anatomy. Recently, the use of non-invasive technologies, such as radiographic computed tomography (CT), increased the knowledge of the neuroanatomy of several extinct and extant ...
