    On this episode, we focus on:

    • The dinosaur of the day: Utahceratops
    • Title means Utah horn face
    • Species: Utahceratops gettyi
    • Species identify is after Mike Getty, who discovered the holotype and helped get well fossils within the Grand Staircase-Escalante Monument
    • Named in 2010 by Scott Sampson, Mark Loewen, Andrew Farke, Eric Roberts, Catherine Forster, Joshua Smith, and Alan Titus
    • Lived within the late Cretaceous in what’s now Utah
    • Discovered within the Kaiparowits Formation (in Grand Staircase) in Utah
    • Holotype consists of a partial cranium
    • Six specimens discovered, together with two partial skulls
    • quadrupedal
    • Giant, about 23 ft (7 m) lengthy
    • About 6 ft (2 m) tall
    • Averaged 3-4 metric tons
    • Cranium was about 7 ft (2.3 m) lengthy
    • Had tons of of tooth in a dental battery, used to chomp down on crops
    • Giant frill and three horns, however the horns over eyes weren’t as massive because the horns over a Triceratops eyes (quick, stubby, and pointed to the facet)
    • Additionally had two holes in its frill, to assist cut back the burden of its cranium
    • Nostril horn caught straight up
    • Horns have been in all probability to draw mates or scare off rivals, probably not used as protection
    • Been likened as a “big rhino with a ridiculously supersized head” by co-author Mark Loewen
    • Named similtaneously Kosmoceratops (identical paper in PLOS One, referred to as “New Horned Dinosaurs from Utah Present Proof for Intracontinental Dinosaur Endemism”)
    • Kosmoceratops had extra ornate horns/frills
    • Utahceratops was bigger than Kosmoceratops
    • As a result of Utahceratops lived in the identical time and place as Kosmoceratops, and these two ceratopsians lived similtaneously different ceratopsids in Montana and Alberta, Canada, scientists suppose there was some barrier in northern Utah to maintain them from mingling. But it surely’s unclear what that barrier may have been
      Within the Cretaceous, western and jap North America was separated by a flooding of water
    • Paleontologist Thomas Holtz stated to Nationwide Geographic Information, “In case you have been a time traveler and also you went again to the late Cretaceous, you may take a ship from the Gulf of Mexico and sail all the way in which as much as the Arctic Ocean and also you wouldn’t see land.”
    • Utahceratops lived on a floodplain with a lot of swamps, ponds, and lakes, in a moist, humid local weather
    • Different dinosaurs within the space included tyrannosaurid Tertophoneus, hadrosaurs Parasaurolophus and Gryposaurus, ceratopsians Nasutoceratops and Kosmoceratops
    • Can see Utahceratops on the Pure Historical past Museum of Utah
    • Ceratopsians have been ornithiscians
    • Lived in North America and Asia
    • That they had beaks and cheek tooth to eat fiberous vegetation
    • Additionally had a frill (used for protection, regulating physique temperature, attracting mates, or signaling hazard)
    • Most likely traveled in herds and will then stampede if threatened
    • Chasmosaurinae is a subfamily of ceratopsid
    • Chasmosaurinae had massive forehead horns and lengthy frills (in comparison with centrosaurines, one other subfamily of ceratopsid, which had quick forehead horns and shorter frills with lengthy spines popping out of the frills)
    • Chasmosaurine fossils have been present in western Canada, the western United States, and northern Mexico.
    • Enjoyable Reality: Other than a number of hadrosaurs (Brachylophosaurus, Gilmoreosaurus, Bactrosaurus and Edmontosaurus) and the latest discovery in a titanosaur, tumors have been discovered on different fossils. Based on Discovery Information: “The oldest recognized case of osteoma dates to the early Carboniferous (a interval spanning 359.2 million to 299 million years in the past) within the North American fish Phanerosteon mirabile. The mosasaur Platecarpus, a marine reptile, additionally had an osteoma, as did a crocodile, Leidyosuchus formidabilis.
