Turtles of the clade Pan-Trionychidae have a rich fossil record in the Old World, ranging from
the Early Cretaceous (Hauterivian) to the Holocene. The clade most probably originated in …

The origin of turtles and their uniquely shelled body plan is one of the longest standing
problems in vertebrate biology. The unfulfilled need for a hypothesis that both explains the …

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 …

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 …

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

The defining masterwork on the evolution of reptiles. Over 300 million years ago, an early
land vertebrate developed an egg that contained the embryo in an amnion, allowing it to be …

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 …

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