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)
  • In all probability an omnivore based mostly on the enamel, and will have eaten crops, bugs, and small vertebrates
  • Had heterodont (completely different formed) enamel within the higher jaw
  • Entrance enamel had been straight and slender, like Eoraptor
  • Enamel within the sides of the jaw had 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 referred to as moss animals, they dwell 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 consists of elements of the jaws, incomplete vertebrae, most of a femur, and an ankle bone (astragalus)
  • Description known as it “imperfectly identified fragmentary materials”
  • Partial cranium is about 1.5 in (4 cm) lengthy
  • In 2005 Rauhut and Remes stated Alwalkeria was a chimera, with elements 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 response to a brand new paper, large tortoises hunt and eat birds.
