Xu & Barrett (2025) review the research on the evolutionary history of feathers from the preceding years. [72] 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.

People first uncovered fossils around San Pedro High School in 1936. They were ancient shells belonging to snails and other mollusks from tens of thousands of years ago.
Millions of prehistoric marine fossils were discovered beneath a California high school over the course of a multi-year construction project. The relics recovered at San Pedro High School included ...
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 ...

Rauisuchians are a category of archosaurs within a larger group called Pseudosuchia, which encompasses all archosaurs more closely related to crocodilians than to birds and other dinosaurs. First named in the 1940s, Rauisuchia was a name exclusive to Triassic archosaurs which were generally large (often 4 to 6 metres (13 to 20 ft)), carnivorous ...
