Dictionary

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

OneLook, Free Dictionary, Wiktionary, Urban Dictionary

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 duckbilled dinosaur discovered in Japan
    on April 27, 2021 at 4:24 pm

    An international team of paleontologists has identified a new genus and species of hadrosaur or duck-billed dinosaur, Yamatosaurus izanagii, on one of Japan's southern islands. The fossilized discovery yields new information about hadrosaur migration, suggesting that the herbivors migrated from Asia to North America instead of vice versa. The discovery also illustrates an evolutionary step as the giant creatures evolved from walking upright to walking on all fours.

    New research suggests juvenile tyrannosaurs were slenderer and relatively faster for their body size compared to their multi-ton parents.

  • Tiny cat-sized stegosaur leaves its mark
    on April 16, 2021 at 4:01 pm

    A single footprint left by a cat-sized dinosaur around 100 million years ago has been discovered in China by an international team of palaeontologists.

  • How many T. rexes were there? Billions
    on April 15, 2021 at 6:26 pm

    With fossils few and far between, paleontologists have shied away from estimating the size of extinct populations. But scientists decided to try, focusing on the North American predator T. rex. Using data from the latest fossil analyses, they concluded that some 20,000 adults likely roamed the continent at any one time, from Mexico to Canada. The species survived for perhaps 2.5 million years, which means that about 2.5 billion lived and died overall.

    The asteroid that took out the dinosaurs left the planet in darkness. What did rainforests in South America look like before the impact, and how did they change as a result?

    Humans evolved in Africa, along with chimpanzees, gorillas and monkeys. But primates themselves appear to have evolved elsewhere—likely in Asia—before colonizing Africa. At the time, around 50 million years ago, Africa was an island isolated from the rest of the world by ocean—so how did primates get there?

  • Geoengineering: 'Plan B' for the planet

    Dismissed a decade ago as far-fetched and dangerous, schemes to tame the effects of global warming by engineering the climate have migrated from the margins of policy debates towards centre stage.

    If a friend boasts of having a "big-brained" dog, your reaction is probably not to ask "relative to what?" You would simply assume your friend thinks their dog is pretty smart. But are we always right to equate big brains with greater intelligence?
