The fossil's bird-like features and unique characteristics provide evidence of a global distribution and evolutionary routes for these carnivorous theropods.
The discovery of Revueltosaurus, a crocodile ancestor, upends the traditional understanding of dinosaur evolution. The fossil finds suggest that herbivorous ornithischians and meat-eating theropods did not co-evolve in the Late Triassic as previously thought.
Scientists have discovered a new species, Falcarius utahensis, in Utah that provides clues about the evolution of plant-eating dinosaurs. The dinosaur had leaf-shaped teeth and a larger gut to digest plant material, and its neck and forelimbs were more elongated for reaching plants.
The discovery of Neuquenraptor argentinus provides the first uncontroversial evidence that raptors roamed beyond the Northern Hemisphere. The find reveals a common raptor ancestor likely existed on both Gondwana and Laurasia supercontinents before they split apart.
Researchers studied Tanytrachelos ahynis fossils from the late Triassic Cow Branch Formation, finding no significant differences in size or morphology between populations of the same species. The team analyzed over 90 specimens and discovered that environmental factors rather than intrinsic differences may be responsible for preservati...
