Episode 267: Polar Dinosaurs from Victoria Australia


    Episode 267 is all about Melanorosaurus, the Triassic “Black Mountain Lizard” sauropodomorph from South Africa.

    We additionally interview Tom Wealthy and Patricia Vickers-Wealthy, two extremely completed paleontologists in Melbourne, Australia. They’ve labored collectively on numerous tasks. Most significantly to dinosaur followers, they named Leaellynasaura, Timimus, Atlascopcosaurus, and others from the Victoria coast. Here’s a PDF on the Dinosaur Dreaming mission that led to many discoveries. Checkout Prime Sci to see their work with science training. And in the event you’re within the space, try the Singapore Science Centre or the Melbourne Museum.

    The dinosaur of the day: Melanorosaurus

    • Sauropodomorph that lived within the Late Triassic in what’s now South Africa (Elliot Formation)
    • Most likely herbivore
    • Had 4 enamel on both sides of the premaxilla and 19 enamel on both sides of the maxilla
    • Quadrupedal, with sturdy limbs like a sauropod and a big physique
    • Estimated to be about 26 ft (8 m) lengthy and weigh 1.3 tons
    • Most likely a facultative biped, which suggests it may stroll or run on two legs, however usually used 4
    • Had a considerably pointed snout
    • Had a triangular cranium
    • Sort species: Melanorosaurus readi
    • Discovered on the north slope of the Thaba ‘Nyama (Black Mountain) in Japanese Cape and Free State Provinces, South Africa
    • Genus title means “Black Mountain Lizard”
    • Described in 1924 by Sidney Haughton
    • Used to have a second species: Melanorosaurus thabensis, named in 1993 by François-Xavier Gauffre based mostly on a femur discovered within the Elliot Formation of Lesotho in 1959. In 2016, a examine discovered that femur and different bones have been really a brand new sort of dinosaur, Meroktenos thabanensis
    • Synonym is Roccosaurus tetrascralis, named in 1984 by Van Herdeen and others, however now thought-about to be a nomen nudum (not a lot information on it)
    • Haughton wrote in 1924, “The bones include a tibia, a fibula, a part of the pelvis, some vertebrae and metatarsals, along with a femur mendacity partly embedded within the overlying sandstone and the proximal half of a humerus discovered weathered down the slope. They’re within the assortment of the South African Museum (Cat. Nos. 3449, 3450).”
    • In 1979 Van Heerden analyzed the kind materials and assigned most of it to Euskelosaurus, apart from a sacral, tibia, and femur
    • In 1997 Van Heerden and Peter Galton referred one other specimen to Melanorosaurus readi based mostly on the femurs being comparable
    • In 2005, Galton, Van Heerden, and Yates stated that many further bones, largely of Plateosauravus have been assigned to Melanorosaurus since 1924
    • Additionally they referred a brand new specimen to Melanorosaurus readi, and stated the dinosaurs was a “Sauropodomorpha incertae sedis pending additional evaluation of the holotype and of all of the referred specimens”
    • In 2007, Yates revised analysis of among the specimens, however not the kind specimens (there have been two, this is called a syntype)
    • Yates additionally described a referred cranium
    • Some uncertainty round Melanorosaurus now, for the reason that syntype specimens haven’t been studied shortly, and ought to be reexamined to determine diagnostic options, and the best way scientists consider Melanorosaurus now’s based mostly on referred specimens
    • However among the referred specimens are not directly referred (they’re referred based mostly on a referred specimen), so it appears Melanorosaurus normally must be reexamined
    • Syntype (each specimens) are housed in Cape City and the referred specimens saved on the Nationwide Museum of Bloemfontein in South Africa

    Enjoyable Truth:
    Benjamin Kear, Tom Wealthy, Patricia Vickers-Wealthy, and others described the primary identifiable dinosaurs present in Saudi Arabia.
