Kotevski et al. (2025) describe new fossil material of theropods from the Lower Cretaceous Strzelecki Group and Eumeralla Formation , including the first carcharodontosaurian fossils from Australia, bones of large-bodied megaraptorids and a tibia of a member of Unenlagiinae. [35]
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]
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 ...
Su et al. (2025) describe two new specimens of Glyphoderma kangi, providing new information on the anatomy of the studied placodont. [4]Marx et al. (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 ...
Hu et al. (2025) report the discovery of new fossil material of Pleistocene mammals from the Dayakou pit (Chongqing, China), including first records of Ailuropoda melanoleuca wulingshanensis, Tapirus sinensis and Leptobos sp. in the Yanjinggou area, and providing new information on changes of mammal faunas from south China during the Early ...
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.
Fossil material of an early-diverging, long-snouted dyrosaurid is described from the Campanian Quseir Formation by Saber et al. (2024). [ 53 ] Jouve & Rodríguez-Jiménez (2024) describe a dyrosaurid vertebra from the Thanetian Cuervos Formation ( Colombia ), providing evidence of survival of dyrosaurids in South America until the end of the ...
