Squamate research
López-Rueda et al. (2025) describe new mosasaur material from the Upper Cretaceous Labor-Tierna and Plaeners formations (Colombia), including the first record of a member of the genus Globidens from northern South America reported to date.[1]
Su et al. (2025) describe two new specimens of Glyphoderma kangi, providing new information on the anatomy of the studied placodont.[3]

Turtle research
Pérez-García (2025) revises the fossil material of "Podocnemis" parva and "P." judaea, interprets the latter species as a junior synonym of the former one, and confirms assignment of "P." parva to the bothremydid genus Algorachelus.[4]
A study on the neuroanatomy of Azzabaremys moragjonesi, providing evidence of convergences of its neuroanatomical structures with those of other turtles adapted to marine environments, is published by Martín-Jiménez & Pérez-García (2025).[5]
Jannello et al. (2025) study shell histology of marine turtles from the Eocene La Meseta and Submeseta formations (Antarctica), and report that histological variation of the studied sample of fossils exceeds its macromorphological variation.[6]
Piñeiro et al. (2025) reevaluate purported evidence for the presence of tail autotomy in mesosaurs, and consider it more likely that purported evidence of autotomy actually shows that mesosaurs may display a previously undocumented vertebral type in their caudal vertebrae.[8]
Redescription of the skull anatomy of Milleropsis pricei is published by Jenkins et al. (2025)[9]
Colombi et al. (2025) report the discovery of an aggregation of four juvenile specimens of Hyperodapedon sanjuanensis from the Ischigualasto Formation (Argentina), interpreted as probable evidence of social and burrowing behavior of the studied rhynchosaur.[10]
Reptiles in general
Marquina-Blasco et al. (2025) describe the assemblage of reptile fossils from the Miocene strata from the Crevillente 2 and Crevillente 15 sites (Spain), possibly including the oldest fossil material of a member of the genus Timon reported to date, and interpret the studied fossils as indicating that the Vallesian Crisis did not have a major impact on the herpetofaunal communities of the Iberian Peninsula.[11]
Evidence from the study of extant reptiles, indicative of utility of studies of calcium and strontium isotope composition of hard tissues for reconstructions of diets of fossil reptiles, is presented by Weber et al. (2025).[12]
