Squamate research
- An iguanian skull from the Paleogene White River Formation (Wyoming, United States), tentatively assigned to the species Aciprion formosum, is interpreted as the oldest and first definitive stem member of Crotaphytidae by Scarpetta (2024); the author also interprets Polrussia mongoliensis as possible member of the crown group of Pleurodonta, Magnuviator ovimonsensis as a possible stem pleurodontan and Afairiguana avius as a possible anole.[4]
- The oldest fossil material of Platecarpus from Europe reported to date, as well as fossil material of Tylosaurus sp, is described from the Santonian localities in the Sougraigne area (Aude Department, France) by Plasse et al. (2024).[5]
- Rempert, Martens & Vinkeles Melchers (2024) describe new fossil material of mosasaurs from the Upper Cretaceous strata in Mississipi (United States), providing evidence of the presence of Mosasaurus hoffmannii during the Maastrichtian and of cf. Platecarpus, an unnamed species of Plioplatecarpus from the Demopolis Chalk and probably of Tylosaurus sp. during the Campanian.[6]
- The first known snake assemblage from early Clarendonian in North America is reported from the Penny Creek Local Fauna (Ash Hollow Formation; Nebraska, United States) by Jacisin & Lawing (2024), who interpret the studied fossils as indicative of a woodland-prairie environment with a permanent stream or river as a local water source.[7]
- ElShafie (2024) presents novel methods which can be used to determine body size from isolated lizard bones and applies these methods to a sample of lizard bones from the Paleogene of North America.[8]

Ichthyosauromorph research
- Campos et al. (2024) redescribe the holotype of Myobradypterygius hauthali, interpreting this species as phylogenetically distant from species belonging to the genus Platypterygius, and consider Myobradypterygius to be a distinct genus.[9]

Other reptile research
- Mooney et al. (2024) describe a skeleton of Captorhinus aguti from the Richards Spur locality (Oklahoma, United States), preserved with integumentary structures interpreted as remnants of the epidermis, and showing surface morphologies of the skin consistent with variation in most extant and extinct reptiles.[15]
