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 first choristoderan record from the Upper Cretaceous of Asia, Tamagawa Formation, Kuji Group, Japan
Abstract Choristoderes are freshwater diapsid reptiles that are distributed through Laurasia in Jurassic–Miocene deposits. The group shows great diversity in the Early Cretaceous of Asia, with all
A new choristodere (Reptilia: Choristodera) from an Aptian–Albian coal deposit in China
Choristoderes are a small clade of freshwater aquatic reptiles known from deposits of Jurassic–Miocene age. They show their greatest diversity in the Early Cretaceous of Asia, with seven recorded
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 new orthophlebiid scorpionfly (Insecta, Orthophlebiidae) from the Late Jurassic Linglongta biota of northern China
ABSTRACT The scorpionfly genus Longiphlebia, with a sole species, is confined to the Middle-Late Jurassic Daohugou biota. Herein, we describe and figure the second species, Longiphlebia incompleta
Osteology, relationships and functional morphology of Weigeltisaurus jaekeli (Diapsida, Weigeltisauridae) based on a complete skeleton from the Upper Permian Kupferschiefer of Germany
TLDR
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
TLDR
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
TLDR
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.
The locomotion of extinct secondarily aquatic tetrapods
TLDR
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
TLDR
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.

EXCEPTIONAL FOSSIL MATERIAL OF A SEMI-AQUATIC REPTILE FROM CHINA: THE RESOLUTION OF AN ENIGMA
TLDR
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
TLDR
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 choristoderan reptile Monjurosuchus from the early Cretaceous of Japan
TLDR
A cladistic analysis was performed in order to place Japanese and Chinese taxa, including the incompletely described Chinese long-necked Hyphalosaurus lingyanensis, into choristoderan phylogeny, and the results support the monophyly of Neochoristodera and a Sino-Japanese clade of long necked Choristoderes.
Early Cretaceous choristoderes (Diapsida, Choristodera) from Siberia, Russia
Abstract There are ten known Lower Cretaceous localities for skeletal remains of choristoderes in Siberia (Russia). Choristoderan remains at all these localities are represented by isolated bones,
The skull of Cteniogenys, a choristodere (Reptilia: Archosauromorpha, from the Middle Jurassic of Oxfordshire
TLDR
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.
