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 …

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 …

Turtles of the clade Pan-Trionychidae have a rich, but fragmentary fossil record in the New
World, ranging from the Late Cretaceous to the Holocene. The clade immigrated to North …

Turtles have served as a model system for molecular divergence dating studies using fossil
calibrations. However, because some parts of the fossil record of turtles are very well known …

Understanding how and why biodiversity is structured across the globe has been central to
ecology, evolution, and biogeography even before those disciplines took their modern …

Trionychid (softshell) turtles have a peculiar bauplan, which includes shell reductions and
cranial elongation. Despite a rich fossil record dating back to the Early Cretaceous, the …

The Paleocene-Eocene Thermal Maximum (PETM) is correlated with the first occurrences of
earliest modern mammals in the Northern Hemisphere. The latest Paleocene Clarkforkian …

The Cretaceous–Palaeogene (K–Pg) mass extinction was responsible for the destruction of
global ecosystems and loss of approximately three-quarters of species diversity 66 million …

Organisms display a considerable variety of body sizes and shapes, and macroevolutionary
investigations help to understand the evolutionary dynamics behind such variations. Turtles …

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 …
