On this episode, we focus on:
Information:
- Two new species of Tyrannosaurus have been proposed, Tyrannosaurus imperator and Tyrannosaurus regina supply
- A brand new alvarezsaurid, Ondogurvel alifanovi, was described from the Late Cretaceous of Mongolia supply
- A brand new hadrosaurid, Kelumapusaura machi, was named from Patagonia and Huallasaurus australis was cut up from Kritosaurus supply
- “Rexor” the T. rex is on show in Manhattan as a part of the Artwork within the Parks open air gallery supply
The dinosaur of the day: Anodontosaurus
- Ankylosaur that lived within the Late Cretaceous in what’s now Alberta, Canada (Horseshoe Canyon Formation)
- Regarded like different ankylosaurs, low to the bottom, on 4 legs, lined in armor, with a membership tail
- Physique lined in armor, and had a large, pointed tail membership
- Tail membership was wider than lengthy
- Had small polygonal plates of bone behind the attention
- Herbivorous
- Two species: Anodontosaurus lambei and Anodontosaurus inceptus
- Kind species is Anodontosaurus lambei
- Fossils present in 1916 by Sternberg
- Named in 1929 by Charles M. Sternberg
- Holotype is {a partially} preserved skeleton that features the cranium and armor, together with the primary cervical half ring (however skeleton was badly crushed)
- Genus title means “toothless lizard”
- Primarily based on the truth that the crushing/compression of the skeleton made it lose its enamel and shift some flat, spherical components from under the cranium to the highest of the decrease jaw, so Sternberg thought there have been massive “trituration plates” as a substitute of enamel
- Species title is in honor of Lawrence Lambe
- In 1986 Coombs discovered one specimen of Anodontosaurus to be a juvenile, primarily based on sacral ribs not being fused to vertebrae (although he thought of Anodontosaurus to be Euoplocephalus)
- Included ribs, vertebrae, proper hindlimb, ft, and different fragments
- In 1971 Walter Coombs mentioned there was just one sort of ankylosaur through the Campanian in North America. He synonymized Anodontosaurus, Dyoplosaurus, and Scolosaurus with Euoplocephalus, however didn’t actually clarify why (talked about variations in cranium dimension and form however no cranium recognized for Dyoplosaurus or Scolosaurus)
- Then Victoria Arbour and others redescribed Dyoplosaurus and mentioned it was legitimate in 2009, and in 2010 mentioned Anodontosaurus was additionally distinct primarily based on the tail membership, cranium ornamentation, and triangular knob osteoderms. She reassigned all of the ankylosaurine specimens from Horseshoe Canyon Formation that have been thought of to Euoplocephalus to Anodontosaurus, primarily based on them having persistently related tail membership knots, so it steered they have been all from the identical taxon
- Three research in 2013 additionally mentioned Anodontosaurus was legitimate (Scolosaurus was additionally discovered to be legitimate)
- Arbour and Phil Currie additionally referred a specimen from Dinosaur Park Formation to Anodontosaurus (lived just a few million years sooner than different specimens)
- In 2018 Paul Penkalski made that specimen the holotype of the brand new species Anodontosaurus inceptus
- Different dinosaurs that lived across the similar time and place embrace the troodontid Albertavenator, the caenagnathids Apatoraptor and Epichirostenotes, ceratopsians Arrhinoceratops and Pachyrhinosaurus, ornithomimids Ornithomimus and Struthiomimus, hadrosaurs Edmontosaurus, Hypacrosaurus, Parksosaurus, Saurolophus, and the tyrannosaur Albertosaurus
- Anodontosaurus is within the recreation Path of Titans
Enjoyable Reality:
Most dinosaur genera solely have a single species and there are a number of good explanation why.
