Thaichelys Ruchae
''Thaichelys'' (meaning "Thai turtle") is a genus of extinct proterochersid stem-turtle from the Late Triassic Huai Hin Lat Formation of Thailand. The type species is ''T. ruchae'' and it was initially classified as a species of ''Proganochelys''. Discovery and naming The first discovered remains referable to ''Thaichelys'' were discovered in 1980 along the road from Ban Huai Sanan Sai to Na Pha Song. The remains were initially described as Testudines indet. by de Lapparent de Broin et al. (1982) before being referred to "''Proganochelys''" ''ruchae'' (now ''Thaichelys ruchae'') in 1984. The specimens have since become lost, but casts exist of all but one of the specimens in the French National Museum of Natural History. In 1981, three more specimens were discovered: SM2015-1-001 (the holotype A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described.

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', ''Herrerasaurus'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful ...

2025 In Reptile Paleontology
This catalog of fossil reptile research published in 2025 includes a list of new taxa that were Species description, described during the year 2025, as well as other significant discoveries and events related to reptile paleontology that occurred in 2025. Squamates New squamate taxa Squamate research * A study on the biogeography of squamates throughout their evolutionary history is published by Wilenzik & Pyron (2025), who identify Europe and northeastern Asia as the most likely areas of the origin of Squamata. * Brownstein et al. (2025) argue that the common ancestor of extant night lizards originated before the Cretaceous–Paleogene extinction event and that members of the group survived the extinction in spite of living in the areas close to the site of the Chicxulub crater, Chicxulub impact crater. * Jiang et al. (2025) review the taxonomic composition, phylogenetic affinities, morphological diversity and geographical distribution of polyglyphanodontians. * Santos et a ...
