A study on the diversification of non-avian dinosaurs, inferred from available dinosaur phylogenies, is published by Allen et al. (2024), who find it impossible to decisively conclude whether dinosaurs experienced a decline in diversity before the Cretaceous–Paleogene extinction event on the basis of available data, noting the impact of the ...
Shapiro (2024) describes fossil material of Dzieduszyckia from the Devonian Slaven Chert (Nevada, United States), possibly indicative of the presence of a species distinct from D. sonora in Nevada, and interprets Dzieduszyckia as capable of survival in both seep and non-seep settings, which enabled it be primed for the Famennian biotic crises ...
The previous record for the smallest non-avian dinosaur egg, according to Guinness World Records, measures 45-by-20 millimeters (about 1.77-by-0.79 inches). Discovered in Japan's Tamba City, this ...
Review of studies of dinosaur reproduction and ontogeny, and of challenges in the studies of dinosaur reproductive biology, is published by Chapelle, Griffin & Pol (2025). [ 15 ] Deiques et al. (2025) report the discovery of new dinosaur tracks from the Upper Jurassic Guará Formation ( Brazil ), including second record of an ankylosaur track ...
The latest dinosaur being mounted at the Natural History Museum in Los Angeles is not only a member of a new species — it's also the only one found on the planet whose bones are green, according ...
While the dinosaurs met their end around 66 million years ago in a catastrophic way, their extinction may have been crucial to the development of the human race.
Iannucci (2024) describes 1.47-million-years-old fragment of a metatarsal bone of a member of the genus Sus from the Peyrolles site , interpreted as evidence of the presence of suids in Europe within the 1.8-to-1.2-million-years-ago interval; [266] however, Martínez-Navarro et al. (2024) subsequently argue that the specimen studied by Iannucci ...
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium.
