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

    New research moves back the moment of the radiation of squamates -- the group of reptiles that includes lizards, snakes and worm lizards -- to the Jurassic, a long time before current estimates.

    Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research. The finding discusses the distribution of hadrosaurids and ceratopsids -- the megaherbivores of the Late Cretaceous Period, 100.5 million to 66 million years ago.

  • Injured dinosaur left behind unusual footprints
    on April 6, 2022 at 8:05 pm

    A set of dinosaur footprints in Spain has unusual features because the dinosaur that made the tracks had an injured foot, according to a new study.

    Extinct for 66 million years, T. rex still inspires speculation about its anatomy, behavior and fierce physique. One conundrum: its peculiarly short forelimbs, which have relatively limited mobility. While scientists have suggested explanations, a paleontologist puts the proposals to the test and finds them wanting. He hypothesizes that the arms reduced in size to limit damage, possibly fatal, when a pack of T. rexes descended on a carcass with their bone-crunching teeth.

    Prehistoric mammals bulked up, rather than develop bigger brains, to boost their survival chances once dinosaurs had become extinct, research suggests.

    What does a modern combine harvester and a Diplodocus have in common? One answer, it seems, may be their big footprints on the soil. A new study led by researchers from Sweden and Switzerland has found that the weight of farming machinery today is approaching that of the largest animals to have ever roamed the Earth—the sauropods.

  • Deindustrialization as fact and fiction
    on May 13, 2022 at 5:03 pm

    The declining importance of manufacturing in rich societies is associated with deep concerns, but also with the hope of opening up new opportunities for economic development. As a result, predictions of a structural change from an industrial to a service society have repeatedly been the subject of political conflicts. To understand how social power structures and conflicts influence such future scenarios, it is important to look at the history of how and by whom post-industrial society has been […]

    Reports of Loch Ness monster sightings keep coming. The latest report, accompanied by a video, is of a 20–30ft long creature occasionally breaking the water's surface. Although the video clearly shows a moving v-shaped wake it does not reveal the underlying source. The witnesses certainly saw something, but what?
