    The dinosaur of the day: Alwalkeria

    • Basal saurischian that lived within the Late Triassic in what’s now India (Maleri Formation)
    • Bipedal, and small
    • Had an elongated head, lengthy arms and lengthy tail
    • In 2010 Gregory Paul estimated it to be about 5 ft (1.5 m) lengthy and weigh 4.4 lb (2 kg)
    • Most likely an omnivore primarily based on the enamel, and should have eaten crops, bugs, and small vertebrates
    • Had heterodont (totally different formed) enamel within the higher jaw
    • Entrance enamel have been straight and slender, like Eoraptor
    • Enamel within the sides of the jaw have been like carnivorous theropods, curved backwards, however they weren’t serrated
    • Enamel are much like Eoraptor. Each have gaps between the enamel within the premaxillary and maxillary bones, within the higher jaw
    • Sort species is Alwalkeria maleriensis
    • Initially named in 1987 by Sankar Chatterjee as Walkeria maleriensis, in honor of paleontologist Alick Walker, however turned out that identify was used for a bryozoa (also called moss animals, they reside in shallow water in colonies)
    • In 1994, Sankar Chatterjee and Ben Creisler renamed the dinosaur Alwalkeria maleriensis
    • Genus identify means “for Alick Walker”
    • Species identify refers back to the Maleri Formation
    • Holotype is incomplete and contains components of the jaws, incomplete vertebrae, most of a femur, and an ankle bone (astragalus)
    • Description referred to as it “imperfectly identified fragmentary materials”
    • Partial cranium is about 1.5 in (4 cm) lengthy
    • In 2005 Rauhut and Remes mentioned Alwalkeria was a chimera, with components of the cranium being a crurotarsan (archosauriform), vertebrae being from different reptiles, however the femur and astragalus being from a dinosaur, and the astragalus having saurischian options
    • Initially regarded as a basal theropod much like Coelophysis and Procompsognathus, then a herrerasaurid, then a basal saurischian
    • Fossils present in purple mudstone
    • One of many earliest identified dinosaurs from India

    Enjoyable Reality:
    In line with a brand new paper, big tortoises hunt and eat birds.
