Episode 256: A brand new titanosaur from Kenya, footprints on Tyrants Aisle, and educating evolution by way of paleoart


    Episode 256 is all about Coloradisaurus, a Triassic sauropodomorph recognized from an almost full cranium that was present in Argentina.

    We additionally interview Taissa Rodrigues, from the Universidade Federal do Espirito Santo in Brazil. She introduced a poster at SVP about educating evolution utilizing paleoart. She additionally led a session on ladies in paleontology and had a pupil current a poster on a pterosaur. Comply with her on twitter @paleotaissa

    On this episode, we focus on:


    • Shows from the primary day of SVP all the abstracts will be learn right here: supply
      • New relationship reveals Lythronax argestes is older than beforehand thought, not coinciding with a world sea-level drop
      • There are tons of latest sauropod fossil fields in southwest Queensland, Australia, close to Eromanga
      • Possible ornithopod, ceratopsid, deinonychosaur, and tyrannosaur tracks have been discovered on a 200ft cliff in Alaska
      • In Alberta, Tyrants Aisle has over 120 tracks possible belonging to Edmontosaurus, a troodontid, Tyrannosaurus, and one other theropod
      • CT scans of monitor slabs reveals how dinosaur toes moved by way of comfortable sediments
      • Laser-stimulated fluorescence (LSF) is getting used to collect proof of the primary aerodynamically important wings
      • A brand new monitor website reveals a pair sauropods strolling collectively when a bigger sauropod skids to keep away from squashing a smaller particular person
      • New sauropod finds in Hateg island Transylvania, Romania could also be a fourth genus, however isn’t full sufficient to get a brand new title
      • Dinosaurs and crocodiles have onerous eggshells that developed independently
      • A brand new titanosaur was present in NW Kenya
      • Low melanosome (shade pigment producer) variety could also be linked to low metabolism
      • Compacted coarse cancellous bone (CCCB) that’s frequent in burrowing animals was discovered within the hind limbs of a brand new Oryctodromeus relative
      • Distinctive fossils don’t essentially translate to good mobile and molecular preservation
      • New opalized femur fragments from an ornithopod in lightening ridge present that younger have been born within the space
      • Melanosomes are usually not sufficient to find out shade. Construction, chemistry, and weight loss plan even have a huge impact
      • Calcium isotopes from Morocco and Niger help Spinosaurus as a fish-eater
      • Extra neornithischian finds from south of Melbourne could finish with one or two synonymized taxa within the close to future
      • New analysis reveals ovarian follicles in an enantiornithine
      • A sauropod footprint was present in a brand new sauropod bone, including to the concept of trampling sauropods
      • A dinosaur stampede like trackway was discovered close to Quilpie, QLD, Australia
      • Coprolites can protect some comfortable tissue options and different details about temperatures and habitats
      • The title Kamuysaurus is supposed to imply that it’s the god of Japanese dinosaurs primarily based on its extremely full skeleton
      • Deep studying can course of CT scans and save time on analyzing photographs
      • Equisetum, or horse tails, have been most likely essentially the most nutritious meals for younger and grownup sauropods
      • Birds use their necks in a wide range of methods, however they have a tendency to have numerous traits in frequent

    The dinosaur of the day: Coloradisaurus

    • Massospondylid sauropodomorph that lived within the Late Triassic in what’s now La Rioja Province, Argentina (Los Colorados Formation)
    • Basal sauropodomorph
    • Thought-about to be medium-sized
    • Gracile
    • Sort species is Coloradisaurus brevis
    • Genus title means “Colorado’s lizard”, and it was named after the Los Colorados Formation, the place it was discovered
    • Initially Jose Bonaparte named it Coloradia in 1978, however it was already assigned to a moth
    • Named in 1983 by David Lambert
    • Holotype features a practically full cranium
    • A second specimen was described in 2012 by Cecilia Apaldetti and others (postcranial materials, together with elements of the vertebral column, pectoral girdle, incomplete forelimb, pelvis, hindlimb)
    • The second specimen was bigger than the holotype, and was most likely a juvenile
    • Cranium has some similarities to plateosaurid skulls, so Coloradisaurus is taken into account to be a massospondylid that by way of convergent evolution has some plateosaurid traits
    • Additionally has some comparable traits to Lufengosaurus, a massospondylid from China (Early Jurassic); we cowl Lufengosaurus is episode 159
    • Different dinosaurs that lived in the identical time and place embody Riojasaurus, Lessemsaurus, and Zupaysaurus

    Enjoyable Truth:
    Wintonotitan, a sauropod from the Winton Formation in Australia, isn’t a titanosaur.
