Dinosaur : any of a group (Dinosauria) of extinct often very large chiefly terrestrial carnivorous or herbivorous reptiles of the Mesozoic era — Webster

Encyclopedia

Dinosaurare a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago; their dominance continued through the Jurassic and Cretaceous periods. Reverse genetic engineering and the fossil record both demonstrate that birds are modern feathered dinosaurs, having evolved from earlier theropods during the late Jurassic Period. As such, birds were the only dinosaur lineage to survive the Cretaceous–Paleogene extinction event 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, which are all dinosaurs other than birds. — Wikipedia

  • CT uncovers bone disease in Tyrannosaurus rex jaw
    on December 1, 2021 at 1:51 pm

    Researchers have identified bone disease in the fossilized jaw of a Tyrannosaurus rex using a CT-based, nondestructive imaging approach. The imaging method could have significant applications in paleontology, researchers said, as an alternative to fossil assessment methods that involve the destruction of samples.

    The two-legged dinosaur Issi saaneq lived about 214 million years ago in what is now Greenland. It was a medium-sized, long-necked herbivore and a predecessor of the sauropods, the largest land animals ever to live. The name of the new dinosaur pays tribute to Greenland's Inuit language and means "cold bone".

  • Tiny pterosaurs dominated Cretaceous skies
    on October 27, 2021 at 4:20 pm

    The newly hatched juveniles of large and gigantic pterosaurs likely out-competed other smaller adult pterosaur species to dominate the Late Cretaceous period around 100 million years ago, a new study has found.

    An international research team at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) of the Technical University of Munich (TUM) have developed a new imaging technology. In the future this technology could not only improve the resolution of neutron measurements by many times but could also reduce radiation exposure during X-ray imaging.
