## Turtles
### New turtle taxa

| Name | Novelty | Status | Authors | Age | Type locality | Country | Notes | Images |
| Calvarichelys | Gen. et sp. nov | Valid | Oriozabala et al. | Late Cretaceous (Campanian–Maastrichtian) | La Colonia Formation | Argentina | A member of the family Chelidae. The type species is C. coloniensis. | |

### Turtle research

* Neto et al. (2025) describe new fossil material of Chelus colombiana from the Miocene Solimões Formation (Brazil), and interpret its morphology as supporting the presence of a single species of Chelus in the Miocene of South America.
* 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.
* 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).
* 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.
* Guerrero et al. (2025) describe and analyze the different types of bioerosion marks present in the shells of the pancheloniids Eochelone brabantica and Puppigerus camperi of the middle Eocene (Lutetian) of Belgium.

### Other reptile research

* 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.
* A redescription of the skull anatomy of Milleropsis pricei is published by Jenkins et al. (2025) based on µCT data.
* A redescription of the skull anatomy of Milleretta rubidgei is published by Jenkins et al. (2025) based on µCT data.
* 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.

## Reptiles in general

* Review of the fossil record of Triassic-Jurassic reptiles from the Connecticut Valley (Connecticut and Massachusetts, United States) is published by Galton, Regalado Fernández & Farlow (2025), who consider Ammosaurus major to be a separate taxon from Anchisaurus polyzelus.
* Fossil material of nothosauroids, indeterminate eosauropterygians and a member of the genus Macrocnemus is described from the Ladinian Sceltrich beds (Meride Limestone, Monte San Giorgio, Switzerland) by Renesto & Magnani (2025), providing evidence of similarity of reptile faunas from the Sceltrich beds and underlying Cassina beds.
* 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.
* 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).
