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.

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 ...
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.
A pinkie bone recovered from Denisova Cave in Siberia’s Altai Mountains in 2010 also led to the idea of a distinct ancient human population, dubbed the Denisovans, that some people share ...
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 ghost of both of these is evident from the fossils found in the area," said Adele Pentland, a doctoral student in paleontology at Curtin University in Australia and lead author of the study ...
This article records new taxa of every kind of fossil archosaur that are scheduled to be described during 2024, as well as other significant discoveries and events related to the paleontology of archosaurs that will be published in 2024.

A study published Wednesday Jan. 16, 2019, found the biggest rise in Siberia, where frozen soil temperatures rose by 0.9 degrees Celsius (1.62 Fahrenheit) between 2007 and 2016. (AP Photo/Arthur Max)
