On this episode, we talk about:

  • The dinosaur of the day: Fosterovenator
  • Identify means “Foster’s hunter”
  • Lived within the Late Jurassic within the Morrison Formation of what’s now Wyoming
  • Charles Marsh and Arthur Lakes collected the bones in 1879, amongst crocodile enamel, turtle shells, a juvenile Allosaurus and Torvosaurus
  • Fosterovenator churei (solely species); named in 2014
  • Identify Fosterovenator is a mix of John R. Foster (a tribute to the American paleontologist) and Venator which suggests “hunter”
  • Named after John Foster to acknowledge “his contributions to the examine of the vertebrate fauna of the Morrison Formation”, in response to the paper “New knowledge on small theropod dinosaurs from the Higher Jurassic Morrison Formation of Como Bluff, Wyoming, USA”
  • Churei comes from Daniel J. Churemu (American paleontologist)
  • Holotype was discovered at Como Bluff in Wyoming (Reed’s Quarry)
  • Holotype features a tibia and ankle bones fused collectively
  • Holotype might be a juvenile, which makes it tougher to find out how the dinosaur appeared (most likely appeared completely different as an grownup)
  • The top of the tibia resembles the suitable tibia of a small theropod discovered within the Morrison Formation, initially regarded as Elaphrosaurus (named by Chure in 2001), however in 2008 Carrano and Sampson stated it could extra resemble Tendaguru than Elaphrosaurus. However there must be extra full specimens to know for positive
  • Fosterovenator is analogous in form to Elaphrosaurus
  • Additionally just like Tendaguru
  • Too fragmentary to know precisely how massive Fosterovenator was
  • A second specimen has a proper fibula of a bigger particular person (fibula is 10.8 in or 27.5 cm lengthy)
  • Fosterovenator reveals there might have been extra range of smaller theropods (which lived amongst Allosaurus, Torvosaurus, Ceratosaurus)
  • Fossils of small and juvenile theropods are uncommon within the Morrison Formation (most likely eaten)
  • In all probability hunted small prey, however might have scavenged on bigger animals, similar to sauropods
  • Fosterovenator is a ceratosaurid, however extra carefully associated to Elaphrosaurus than to Ceratosaurus
  • Ceratosauridae is a household of theropods
  • Sort genus is Ceratosaurus
  • Lived within the Jurassic and Cretaceous
  • They lived in North America, Tanzania, Portugal
  • Charles Marsh named the household Ceratosauridae for the sort species (1884)
  • Two varieties of enamel: one with longitudinal ridges and one with clean enamel
  • In all probability competed with allosaurs for meals (the North American ones)
  • Enjoyable reality: A T. rex footprint is about 1.55 ft (46 cm) lengthy. However its ft had been for much longer, about 3.3 ft (1 m) lengthy, as a result of T. rex, like different dinosaurs, walked on its toes.
