T. rex may not be the king of dinosaurs after all. An unearthed skull has revealed a close relative of the T. rex that may have been even larger than the previously-crowned apex predator.
The dino tracks are believed to have been made by multiple species about 166 million years ago. They were found at the Dewars Farm Quarry in Oxfordshire, England.
Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. D. schrani is known from two partial skeletons discovered in Upper Cretaceous (Campanian to Maastrichtian; approximately 76–70 Ma) rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina.
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 ...
Evidence of the impact of the interplay of abiotic and biotic processes on the evolution of pseudosuchians is presented by Payne et al. (2023). [13]A study on the biomechanical properties of the skull of Riojasuchus tenuisceps is published by Taborda, Von Baczko & Desojo (2023), who propose that R. tenuisceps could have had a wading habit, feeding on small-sizey prey caught from the shoreline.
With his 2014 assignment of skull CMN 8801 to Kosmoceratops sp. and his naming of a new species of Pentaceratops (P. aquilonius), both from the Dinosaur Park of Alberta, Longrich argued against the idea of distinct northern and southern dinosaur provinces, since the two genera were now known from both southeastern and northern North America.
Pliosaurs dominated the oceans at a time when dinosaurs roamed the land. The unearthed fossil is about 150 million years old, almost 3 million years younger than any other pliosaur find.
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 ...
