Xu & Barrett (2025) review the research on the evolutionary history of feathers from the preceding years. [71] Brown et al. (2025) describe a cervical vertebra of a juvenile specimen of Cryodrakon boreas from the Dinosaur Park Formation (Alberta, Canada), preserved with a bite mark interpreted as likely produced by a crocodilian. [72]
Reijenga & Close (2025) study the fossil record of Phanerozoic marine animals, and argue that purported evidence of a relationship between the duration of studied clades and their rates of origination and extinction can be explained by incomplete fossil sampling. [46] Maletz et al. (2025) revise Paleozoic fossils with similarities to feathers ...
Fossil material of a giant titanosaur sauropod, distinct from Andesaurus and probably exceeding Patagotitan in size, is described from the Cenomanian Candeleros Formation by Otero et al. (2021). [241] Revision of known fossil material of Pellegrinisaurus powelli and a study on the skeletal anatomy, bone histology and phylogenetic relationships ...
Fossils found in China may add a new branch to the human family tree. ... 2025 at 11:00 AM. Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter.
Fossils from before the mass extinction have only been found around the Equator, but after the event fossils can be found all over the world. [13] Suggested explanations for this include: Archosaurs made more rapid progress towards erect limbs than synapsids, and this gave them greater stamina by avoiding Carrier's constraint.
This list of fossil molluscs described in 2025 is a list of new taxa of fossil molluscs that were described during the year 2025, as well as other significant discoveries and events related to molluscan paleontology that occurred in 2025.

(2025) report evidence of preservation of skin traces, including smooth skin on the tail and scaly skin on the flippers, as well as evidence of preservation of melanosomes and keratinocytes in a plesiosaur specimen from the Lower Jurassic Posidonia ...
