In dinosaur news this week:

  • News from the 3rd day of talks at the 2019 meeting of the Society of Vertebrate Paleontology
    • Dinosaurs had many different skull, jaw muscle, and brain sizes, but we can only easily study the small group that survived the mass extinction
    • By using evo-devo we can now see how exactly bird skulls form around their brains
    • Non-avian Dinosaurs quickly evolved many different skulls and jaws, but they don’t always reflect their feeding strategies
    • We don’t see evidence of dinosaurs before the Carnian Pluvial Event, but fossil localities are limited
    • A new statistical approach may make it easier to separate male and female dinosaur fossils
    • Some quadrupedal dinosaurs had much larger hindfeet than front-feet, but the reason is still unclear
    • Massospondylus had very flexible growth rates, possibly indicating it was a “recovery taxa” taking advantage of the end Triassic extinction
    • New Triceratops excavations found rare remains beyond just the skull, allowing us to measure how they changed as they grew
    • Late cretaceous ceratopsian brains changed shape to allow for the massive neck muscles they needed to hold up their head
    • Australia has the best ankylosaurs from Gondwana including the new “Julia Creek” specimen
    • A new, larger, Liaoningosaurus fossil was found by a farmer in China
    • Microstructure of pachycephalosaur domes may show that they did but heads
  • In Casper, Wyoming, the Tate Geological Museum now has Nicole the Torosaurus on display
  • The Natural History Museum in London is taking student applications to study ceratopsian phylogeny
  • Austria is releasing a set of 12 glow in the dark 3-euro dinosaur coins
  • Mattel Films is partnering with Daniel Kaluuya’s production company to make a live action Barney the dinosaur movie
  • Jurassic World 3 will star DeWanda Wise and Mamoudou Athie, and will bring back characters Ian Malcolm, Ellie Sattler, and Alan Grant will be in the film
