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. [45] Maletz et al. (2025) revise Paleozoic fossils with similarities to feathers ...
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 ...
Scientists have unearthed in southeastern China the fossil of a quail-sized bird that lived about 150 million years ago during the Jurassic Period and possessed surprisingly modern traits, a ...
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 ...
The fossil, examined under a microscope and with micro-CT scans, has a conical puncture a sixth of an inch (4 mm) wide that appears to be the bite mark of a crocodilian that either preyed on the ...
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 ...
The oldest fossil evidence for paravians — the dinosaur group that includes the earliest birds and their closest relatives — appears around the middle of the Jurassic Period (201.3 million to ...
