    The dinosaur of the day: Teratophoneus

    • Tyrannosaurid that lived within the Late Cretaceous in what’s now Utah, US
    • Carnivorous, and appears like typical, ferocious theropod tyrannosaur, with sharp enamel and proportionally quick arms
    • Holotype initially estimated to be about 20 ft (6 m) lengthy and weigh 1,470 lb (667 kg)
    • In 2016 Molina-Pérez and Larramendi estimated Teratophoneus to be 21 ft (6.4 m) lengthy
    • Gregory Paul estimated Teratophoneus to be 26 ft (8 m) lengthy
    • Appears to be like completely different from extra northern tyrannosaurs. Potential there’s a barrier (sea barrier?) that saved dinosaurs separate within the north and south and so they developed in numerous methods
    • In comparison with Albertosaurus, had a deeper cranium and shorter proportionally between the tip of the snout and the entrance of the attention socket (particularly the lacrimal bone of the antorbital fenestra). May imply it had stronger jaw muscle tissues, which meant it had a powerful chew pressure
    • Sort and solely species is Teratophoneus curriei
    • Genus title means “monstrous assassin”
    • Species title in honor of Phil Currie
    • Named in 2011 by Thomas Carr and others
    • Discovered an incomplete cranium and postcranial skeleton
    • Discovered within the Kaiparowits Formation
    • Holotype is BYU 8120, two different specimens have been referred to Teratophoneus: UMNH VP 16690 and UMNH VP 16691
    • Holotype fossils initially considered from 4 completely different people, then later discovered to be most likely from one particular person, a subadult
    • Specimen excavated in 2017 in Grand Staircase-Escalante Nationwide Monument, and was airlifted to the Pure Historical past Museum of Utah on October 15, 2017
    • Airlifted specimen was present in 2015, when Alan Titus was prospecting for fossils. Turned out to be an articulated, almost full skeleton, perhaps 80% (cranium and a lot of the physique, solely lacking again a part of the tail and some toes, unclear in regards to the arms)
    • Specimen was in plaster and lifted in items. The most important piece weighed about 1 ton
    • Juvenile specimen, and possibly was buried in a river channel or in a flooding occasion
    • Estimated to be 17 to twenty ft (5 to six m) lengthy
    • Took the crew and volunteers about 2,000-3,000 hours to excavate the location, and can most likely take not less than 10,000 hours to arrange the specimen
    • Being ready and studied on the Pure Historical past Museum of Utah, and can have a look at progress patterns, how Teratophoneus moved, how briskly it ran, and the way it used its jaws
    • Different animals that lived across the similar time and place embrace hadrosaurs, ceratopsians, mammals, turtles, crocodilians like Deinosuchus, lizards, bugs, snails, clams, fish, and amphibians

    Enjoyable Reality: Throughout a part of the Late Cretaceous: Asia & Europe have been separated by the Turgai sea. Similar to North America was cut up into Laramidia & Appalachia by the Western Inside Seaway.
