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 ...
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 ...
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 ...
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 ...
