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).
Call it shovel and pail-eontology. Three North Dakota boys made the extraordinary discovery of a highly rare Tyrannosaurus rex fossil that could change what we know about dinosaurs.
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 ...
A 10-year-old found 220-million-year-old dinosaur tracks in Wales while fossil hunting.. Tegan Jones and her mother found the tracks, which hadn't been seen in over 140 years. An expert thinks a ...
Fragment of long bone of a dinosaur is described from the Upper Cretaceous (Santonian–Campanian) sediments near the village of Izhberda (Orenburg Oblast, Russia) by Skutschas et al. (2022), who interpret the histological features of this bone as indicative of rapid continuous growth known in large-sized dinosaurs, and interpret this finding ...
The Children's Museum reopened its revamped Dinosphere in March of 2022, and it added several finds from the Big Horn Basin dig site. Those include two sauropods, about 65 feet long each; a marine ...
Dinosaurs evolved from archosaurs with this hip arrangement. The hip sockets faced downwards and the knobs on the femurs were in line with the femur. This "pillar-erect" arrangement appears to have evolved independently in various archosaur lineages, for example it was common in "Rauisuchia" (non-crocodylomorph paracrocodylomorphs ) and also ...
A nearly complete and intact dinosaur skeleton has been excavated in France. The specimen is a Titanosaur, one of the largest dinosaurs of its time. 70 million-year-old giant dinosaur skeleton ...
