The idea that interspecific variation in trophic morphology among closely related species
effectively permits resource partitioning has driven research on ecological radiation since …

The morphology of the temporal region in the tetrapod skull traditionally has been a widely
discussed feature of vertebrate anatomy. The evolution of different temporal openings in …

Evolutionary transitions to marine habitats occurred frequently among Mesozoic reptiles.
Only one such clade survives to the present: sea turtles (Chelonioidea). Other marine turtles …

Recent studies suggested that many fossil marine turtles might not be closely related to
extant marine turtles (Chelonioidea). The uncertainty surrounding the origin and …

Diffusible iodine‐based contrast‐enhanced Computed Tomography (diceCT) is now a
widely used technique for imaging metazoan soft anatomy. Turtles present a particular …

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 …

Chelonioid turtles are the only surviving group of reptiles that secondarily evolved marine
lifestyles during the Mesozoic Early chelonioid evolution is documented by fossils of their …

Knowledge of the early evolution of sea turtles (Chelonioidea) has been limited by
conflicting phylogenetic hypotheses resulting from sparse taxon sampling and a superficial …

Abstract The anatomy of North American tortoises is poorly understood, despite a rich fossil
record from the Eocene and younger strata. Stylemys nebrascensis is a particularly …
