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 ...
Bao et al. (2025) redescribe Tigrivia baii. [17] Sánchez et al. (2025) argue that purported brood balls of dung beetles from the Eocene La Meseta Formation are not true trace fossils, and consider Patagonian trace fossils of Coprinisphaera to represent the southermost known record of this ichnotaxon. [18]
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.
Đaković, Mrdak & Gawlick (2025) describe three assemblages of Anisian ammonoids from the Komarani and Bulog formations (), including fossils of Ptychites rugifer, Megaphyllites obolus, Parakellnerites rothpletzi, Apleuroceras decrescens, Proteusites labiatus, Tropigastrites lahontanus, Proarcestes pannonicus, Proarcestes subtridentinus and Aristoptychites sp. extending known geographical ...
Doughty et al. (2025) use a mechanistic model to study the relationship between seed size of flowering plants, their light environment and the size of animals in their environment, and predict a rapid increase of seed size during the Paleocene that eventually plateaued or declined, likely as a result of the appearance of large herbivores that opened the understory, reducing the competitive ...
Marquina-Blasco et al. (2025) describe the assemblage of reptile fossils from the Miocene strata from the Crevillente 2 and Crevillente 15 sites , 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 ...
This list of fossil fish research presented in 2025 is a list of new fossil taxa of jawless vertebrates, placoderms, cartilaginous fishes, bony fishes, and other fishes that were described during the year, as well as other significant discoveries and events related to paleoichthyology that occurred in 2025.
