Assembled here is a reasonably complete list of annotated codes for historical and modern
natural history collections associated with lost and extant specimens of fossil and Recent …

Turtles (Testudinata) are the clade of amniotes characterized by a complete turtle shell. New
insights into the phylogeny of the group have revealed that a diverse assemblage of fossil …

Over the last 25 years, researchers, mostly paleontologists, have developed a system of
rank-free, phylogenetically defined names for the primary clades of turtles. As these names …

Molecular analyses of turtle relationships have overturned prevailing morphological
hypotheses and prompted the development of a new taxonomy. Here we provide the first …

The cranial circulation and innervation systems of turtles have been studied for more than
two centuries and extensively used to understand turtle systematics. Although a significant …

Abstract The Late Cretaceous was a time of tremendous global change, as the final stages
of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to …

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 …

Abstract Background Turtles (Testudinata) are a successful lineage of vertebrates with about
350 extant species that inhabit all major oceans and landmasses with tropical to temperate …

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 …
