New fossil material of the problematic reptile species Pachystropheus rhaeticus from the uppermost Triassic (Rhaetian) of England, and re-examination of other specimens, demonstrate that it may be the earliest known example of the Choristodera, a poorly understood group of semi-aquatic diapsid reptiles. As a result, the fossil record of choristoderes is extended back in time by approximately 45 million years and a significant gap in the fossil record of these reptiles is highlighted. Failure of…

Choristoderes and the freshwater assemblages
TLDR
The gavial-like neochoristodere Champsosaurus is the most familiar taxon, characterised by large size, a long rostrum and flared temporal fenestrae, but research over the last three decades has revealed many new genera and exposed an unexpected diver sity.
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.
Choristoderes and the freshwater assemblages of Laurasia
TLDR
The gavial-like neochoristodere Champsosaurus is the most familiar taxon, characterised by large size, a long rostrum and flared temporal fenestrae, but research over the last three decades has revealed many new genera and exposed an unexpected diversity.
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…
The Origin, Early History and Diversification of Lepidosauromorph Reptiles
The reptilian group Lepidosauria diversified through the Mesozoic, survived the end-Cretaceous extinction relatively unscathed, and has more than 7,000 living species. Although originally constituted…
Enigmatic basal archosauromorph from the Late Triassic of Poland
TLDR
Describing of newly discovered fossil material along with the histology sections of such an important group of tetrapods that are choristoders is of great significance, not only for the Triassic tetrapod communities, but for tetrapOD evolution, development, ecology and life history in general.
The first record of a nearly complete choristodere (Reptilia: Diapsida) from the Upper Jurassic of Hebei Province, People’s Republic of China
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…
PROGRESS AND FUTURE DIRECTIONS IN ARCHOSAUR PHYLOGENETICS

    Journal of Paleontology

TLDR
The basic structure of archosaurian phylogeny is understood to include two primary crown-group lineages—one leading to living crocodiles and including a broad diversity of Triassic animals and another leading to dinosaurs.
NEW CHORISTODERES (REPTILIA : DIAPSIDA) FROM THE UPPER CRETACEOUS AND PALAEOCENE, ALBERTA AND SASKATCHEWAN, CANADA, AND PHYLOGENETIC RELATIONSHIPS OF CHORISTODERA
TLDR
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.
Fossil vertebrate faunas of the British Rhaetian (latest Triassic)
  • G. Storrs
  • Environmental Science, Geography
  • 1994
TLDR
Rhaetian fossil vertebrate faunas of Britain represent rich but biased samples of taxonomic diversity during uppermost Triassic time, and analysis of element abundance in the disarticulated Westbury Formation assemblage indicates that many parts of some taxa are never preserved while other elements of the same form are common.

TLDR
Analysis of element abundance in the disarticulated Westbury Formation assemblage indicates that many parts of some taxa are never preserved while other elements of the same form are common, suggesting that many species may be missing entirely from this long-studied but poorly understood taphocoenosis.
AMNIOTE PHYLOGENY AND THE IMPORTANCE OF FOSSILS
TLDR
The importance of the critical fossils seems to reside in their relative primitive‐ness, and the simplest explanation for their more conservative nature is that they have had less time to evolve.
Simoedosaurus dakotensis, new species, a diapsid reptile (Archosauromorpha; Choristodera) from the Paleocene of North America
ABSTRACT A partly complete skeleton from the late Paleocene of western North Dakota is described as Simoedosaurus dakotensis, n. sp., and is compared with European individuals of the genus. This…
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.
