Rapid growth in Late Cretaceous sea turtles reveals life history strategies similar to extant leatherbacks

Modern sea turtle long bone osteohistology has been surprisingly well-studied, as it is used to understand sea turtle growth and the timing of life history events, thus informing conservation

A gigantic bizarre marine turtle (Testudines: Chelonioidea) from the Middle Campanian (Late Cretaceous) of South-western Europe

Marine turtles were common in the subtropical Upper Cretaceous epi-continental seas that once washed the coasts of the ancient European archipelago. But unlike its contemporaneous faunas from North

Гигантская морская черепаха из верхнего мела Поволжья, "Природа"

Обсуждается значение находки ископаемых остатков гигантской черепахи Protostega gigas, а также других морские черепах из отложений кампанского яруса (верхний мел) местонахождения Белое Озеро.



Catapleura Cope, 1870 is Euclastes Cope, 1867 (Testudines: Pan-Cheloniidae): synonymy revealed by a new specimen from New Jersey

A new specimen of the pan-cheloniid turtle Euclastes is described which demonstrates that another pan-Cheloniid he named in 1870, Catapleura, is actually the same taxon, and Euclaste wielandi was found to be the most basal species of the genus.

A nomenclature for fossil and living turtles using phylogenetically defined clade names

This work converts the vast majority of previously defined clade names for extinct and extant turtles into this new nomenclatural framework, and establishes 113 clade Names, of which 79 had already received phylogenetic definitions and 34 are new.

A large pteranodontid pterosaur from the Late Cretaceous of Eastern Europe

The Campanian Beloe Ozero locality within the Rybushka Formation in Saratov Province, Russia, is one of the richest and most diverse Upper Cretaceous pterosaur localities in Europe. It produces

Asmodochelys parhami, a new fossil marine turtle from the Campanian Demopolis Chalk and the stratigraphic congruence of competing marine turtle phylogenies

A new genus and species of marine turtle is described from the Upper Campanian Demopolis Chalk of Alabama and Mississippi, USA represented by three partial shells andPhylogenetic analysis shows that A. parhami belongs to the ctenochelyids, an extinct group that shares characteristics with both pan-chelonioids and pan-cheloniids.

and Oldest known marine turtle? A new protostegid from the Lower Cretaceous of Colombia.

Recent studies suggested that many fossil marine turtles might not be closely related to extant marine turtles (Che-lonioidea). The uncertainty surrounding the origin and phylogenetic position of

Anatomy of Rhinochelys pulchriceps (Protostegidae) and marine adaptation during the early evolution of chelonioids

A phylogeny of turtles with increased chelonioid taxon sampling and revised postcranial characters is provided, recovering protostegids as stem-chelonioids, which imply a mid Early Cretaceous origin of total-group chelonIOids and an early Late Cret Jurassic age for crown-chelanioids.

A new phylogenetic hypothesis of turtles with implications for the timing and number of evolutionary transitions to marine lifestyles in the group

A new phylogenetic hypothesis informed by high resolution computed tomographic data of living and fossil taxa is presented, indicating three independent evolutionary transitions to marine life in non‐pleurodiran turtles (plus an additional two‐three in pleurodires).
