Choristodera are freshwater aquatic reptiles known from the Middle Jurassic to the Miocene. Their fossil record shows a peak in diversity in the Early Cretaceous of eastern Asia, most notably in the Jehol Biota of China but also in Japan and Mongolia. However, until now, the only Jurassic records from Asia have been rare disarticulated elements from Middle Jurassic microvertebrate sites in Transbaikalian Siberia, with a possible jaw fragment from the Late Jurassic of Xinjiang, China. Here we…

The skulls and skeletons of two new choristoderes from a single Paleocene ecosystem in western North America are described that reveal the hidden Cenozoic diversity of this reptile clade and strengthen the evidence for the existence of distinctive freshwater faunas in Paleogene Eurasia and North America.

Revealing body proportions of the enigmatic choristodere reptile Khurendukhosaurus from Mongolia

Khurendukhosaurus is an enigmatic genus of choristodere, recorded from the Lower Cretaceous of East Asia, Mongolia, and Siberian Russia. Until now, it was known only from isolated skull and

A neomorphic ossification connecting the braincase, squamosal, and quadrate in choristoderan reptiles: insights from µCT data

Choristoderes are extinct semi-aquatic to aquatic diapsid reptiles, occupying a similar niche as modern crocodilians from the Jurassic to the Miocene. Distinct from other diapsids, choristoderes have

A new orthophlebiid scorpionfly (Insecta, Orthophlebiidae) from the Late Jurassic Linglongta biota of northern China

Osteology, relationships and functional morphology of Weigeltisaurus jaekeli (Diapsida, Weigeltisauridae) based on a complete skeleton from the Upper Permian Kupferschiefer of Germany

A number of intriguing anatomical features are recognized in the weigeltisaurid skeleton described here, including hollow horns on the post-temporal arch, lanceolate teeth in the posterior portion of the maxilla, the absence of a bony arch connecting the postorbital and squamosal bones, and phalanges that resemble those of extant arboreal squamates, and patagial rods that are positioned superficial to the lateral one third of the gastral basket.

Computed tomography analysis of the cranium of Champsosaurus lindoei and implications for the choristoderan neomorphic ossification

The cranial anatomy of the choristodere Champsosaurus lindoei was examined using high‐resolution micro‐computed tomography scanning and it was found that the paired gaps on the ventral surface of the skull do pertain to the fenestrae ovales, an unusual arrangement that may be convergent with some plesiosaurs, some aistopods, and some urodeles.

The internal cranial anatomy of Champsosaurus lindoei and its functional implications

The presence of the putative neomorphic bone is confirmed, which may be homologous with the pre-existing stapes, or developed through incomplete fusion of dermatocranial ossification centres, and geometric morphometric analyses of the semicircular canals suggest that Champsosaurus were well adapted for an aquatic lifestyle.

An overview of the latest research on the locomotion of extinct secondarily aquatic tetrapods, with a focus on amniotes, highlighting the state‐of‐the‐art experimental approaches used in this field and discussing the suitability of these techniques for exploring different aspects of locomotory adaptation.

Raman Spectroscopy Detects Amorphous Carbon in an Enigmatic Egg From the Upper Cretaceous Wido Volcanics of South Korea

Raman spectroscopy has been widely used in micropaleontology and organic geochemistry to identify carbonaceous materials and evaluate their thermal maturity in fossils or metasedimentary rocks.



A new choristodere (Reptilia: Diapsida) from the Lower Cretaceous of western Liaoning Province, China, and phylogenetic relationships of Monjurosuchidae

A new monjurosuchid is named and described based on a nearly complete skull and postcranial skeleton from the Early Cretaceous Chiufotang Formation exposed near Chaoyang, western Liaoning Province, China, and a new classification scheme is proposed for choristoderes on the basis of the recovered phylogenetic framework of the group.

New Material of the Choristodere Lazarussuchus (Diapsida, Choristodera) from the Paleocene of France

ABSTRACT Choristodera is a clade of freshwater aquatic reptiles with a strictly Laurasian distribution and a temporal record extending from at least Middle Jurassic to Miocene. The large


Well-preserved skulls and mandibles from the Oldman and Horseshoe Canyon formations, Alberta, document a new species of Champsosaurus and clarify the status of previously known species of the genus.


The newly recovered Monjurosuchus specimens from western Liaoning show unique integumentary structures of this aquatic reptile for the first time, providing important new information on the soft anatomy and lifestyle of choristoderes.

A New Basal Salamandroid (Amphibia, Urodela) from the Late Jurassic of Qinglong, Hebei Province, China

Comparative study of the new salamander with previously known fossil and extant salamandroids sheds new light on the early evolution of the Salamandroidea, the most species-diverse clade in the Urodela.

The skull of Cteniogenys, a choristodere (Reptilia: Archosauromorpha, from the Middle Jurassic of Oxfordshire

Comparison with known choristoderes, based on an analysis of 53 derived character states, suggests that Ctemogenys is the most primitive of known genera, which supports recent analyses which conclude that Champsosaurus and Simoedosaurus are derived from archosauromorph diapsids, not lepidosauromorphics as once thought.

The first record of a long-snouted choristodere (Reptilia, Diapsida) from the Early Cretaceous of Ishikawa Prefecture, Japan

A longirostrine choristoderan reptile is described from the Early Cretaceous Tetori Group on the basis of an associated specimen from the Kuwajima Formation, Ishikawa Prefecture. This is the first

The earliest possible choristodere (Diapsida) and gaps in the fossil record of semi-aquatic Reptiles

Failure of the record to reveal the evolutionary histories of those reptilian taxa that are most prone to fossilization emphasizes the need for rigorous, character-based studies in phylogenetic analysis of tetrapod lineages, rather than reliance upon stratigraphical position as an indicator of phylogenetic branching sequence.
