A study on bone histology of Trialestes romeri, providing evidence of a rapid growth rate, is published by Ponce, Cerda & Desojo (2025). [4] A study on the biodiversity of thalattosuchians throughout their evolutionary history, attempting to identify factors driving thalattosuchian evolution, is published by Forêt et al. (2025). [5]
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 ...
Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; Maniraptora includes birds, the only known dinosaur group alive today. [5] Most feathered dinosaurs discovered so far have been coelurosaurs.
Scientists in Australia used artificial intelligence to get to the truth behind some 93-million-year-old dino tracks.
More than 260 dinosaur footprints discovered in Brazil and Cameroon provide further evidence that South America and Africa were once connected as part of a giant continent millions of years ago.
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 ...
Evidence suggests that all dinosaurs were egg-laying, and that nest-building was a trait shared by many dinosaurs, both avian and non-avian. While dinosaurs were ancestrally bipedal , many extinct groups included quadrupedal species, and some were able to shift between these stances.
The evidence was seen as supporting the inference from the "Fighting Dinosaurs" fossil that Protoceratops was part of the diet of Velociraptor. [53] In 2012, Hone and colleagues published a paper that described a Velociraptor specimen with a long bone of an azhdarchid pterosaur in its gut. This was interpreted as showing scavenging behaviour. [54]
