    The dinosaur of the day: Austroraptor

    • An unenlagiine dromaeosaurid that lived within the Late Cretaceous in what’s now Argentina (Allen Formation, in Rio Negro)
    • One of many largest recognized dromaeosaurids

    • Virtually as huge as Utahraptor
    • Estimated to be 16 ft (5m) lengthy, although Gregory Paul later estimated it to be 20 ft (6 m) lengthy and weigh 660 lb (300 kg)
    • Bipedal carnivore

    • Had a low, elongated cranium (might have had a weaker chunk drive)
    • Had conical, non-serrated tooth with no denticles, which Novas and others, who named Austroraptor, in comparison with spinosaurid tooth
    • Had brief arms for a dromaeosaurid (often dromaeosaurids have lengthy arms)

    • Humerus was lower than half the size of the femur (about 46%), in comparison with 76% in Deinonychus
    • Not carefully associated, however has been in comparison with T. rex due to its brief arms
    • As an unenlagiine, might have been runner and higher at pursuing prey than different dromaeosaurids. Gracile, so might run quick for lengthy durations of time, and had comparatively skinny, lengthy metatarsals. These items imply they might chase after small, quick animals

    • Fashions for dromaeosaur relative Buitreraptor has recommended that it traveled lengthy distances to chase after prey and used its lengthy forelimbs and sickle-claw to damage or kill prey, and doubtless swallowed its meals complete with its non-serrated tooth, used tooth to carry prey
    • Related mannequin proposed for Austroraptor, although it might not have held its prey as a result of its arms have been too brief, and its tooth have been conical and attainable stronger, so it might have used its tooth when searching

    • Holotype contains components of the cranium, decrease jaw, vertebrae, ribs, humerus, and components of the legs
    • Genus identify means “Southern thief”
    • Species identify is in honor of Alberto Cabaza, who based the Museo Municipal de Lamarque the place the fossil was partially studied

    • Phil Currie and Ariana Paulina-Carabajal referred a second specimen to Austroraptor in 2012 that had been present in 2008 (grownup partial skeleton with a cranium just a little smaller than the holotype, and contains issues lacking within the holotype just like the decrease arm, hand, and foot)
    • Earliest recognized Gondwanan dromaeosaurids, and helps present that enormous dromaeosaurids have been a number of the massive predators alongside abelisaurids
    • Lived alongside titanosaurs similar to Laplatasaurus and Saltasaurus, birds similar to Limenavis, and hadrosaurids similar to Bonapartesaurus and Lapampasaurus
