}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…

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

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
- Environmental ScienceJournal of anatomy
- 2020
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.

- Environmental Science
- 2019
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.

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 earliest possible choristodere (Diapsida) and gaps in the fossil record of semi-aquatic Reptiles
- Environmental Science, GeographyJournal of the Geological Society

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.
