The labyrinth of the vertebrate inner ear is a sensory system that governs the perception of
head rotations. Central hypotheses predict that labyrinth shape and size are related to …

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 …

Turtles are a charismatic reptile group with a peculiar body plan, which most notably
includes the shell. Anatomists have often focused descriptive efforts on the shell and other …

Turtles are relatively species-poor, but anatomically very distinct from other reptiles, which
yields longstanding debates about their origin among amniotes. On the other hand, an …

Late Jurassic deposits across Europe have yielded a rich fauna of extinct turtles. Although
many of these turtles are recovered from marine deposits, it is unclear which of these taxa …

The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal
fenestrae and loss of cranial joints (ie, characteristics of anapsid, akinetic skulls). Evolution …

Turtles have high shape variation of their mandibles, likely reflecting adaptations to a broad
variety of food items and ingestion strategies. Here, we compare functional disparity …

The mandible of turtles is rich in osteological characters that are relevant for systematic
purposes. Shape variation additionally reflects upon various feeding strategies and are thus …

Fossils of Testudines from the Cretaceous Bauru Group in Brazil have been known since the
beginning of the last century. However, our knowledge about them is still limited. In this …

The early evolution of Pan-Chelonioidea (sea turtles) is poorly understood. This is in part
due to the rarity of undeformed skulls of definitive early stem chelonioids. In this work, we …
