Pronunciation: Stru-thee-oh-my-mus. Meaning of name: "Ostrich mimic", due to its resemblance to an Ostrich. Species: S. altus, S. sedens Size: Depending on the species, between 4 and 6 metres long, 2 metres tall and weighing between 150kg and 420kg. Family: Ornithomimidae. Diet: Unknown. Possible omnivore. First fossils found: Known from several individuals. First discovered by Canadian palaeontologist, Lawrence Lambe, in 1901. Named as a species of Ornithomimus by Mr. Lambe in 1902. Almost-complete skeleton discovered by American palaeontologist, Barnum Brown, in Alberta, Canada, in 1914. Re-named Struthiomimus by American palaeontologist, Henry Fairfield Osborne, in 1917. S. sedens named in 2015. It's believed Struthiomimus could sprint at speeds of up to 80km/h, slightly faster than a modern Ostrich. Lived: Depending on the species, 78 to 67 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous in what is now western Canada and the western United States.
Today's "Dino of the Day!" is one of T-Rex's relatives: Daspletosaurus.
Pronunciation: Das-plee-toe-sore-us. Meaning of name: "Frightful lizard". Species: D. torosus, D. horneri Size: Between 8 and 9 metres long, 3 metres tall and weighing between 2 and 4 metric tonnes. Family: Tyrannosauridae. Diet: Carnivore. First fossils found: Known from six well-preserved specimens, the first of which was discovered by American-Canadian palaeontologist, Charles Mortram Sternberg, in the Oldman Formation of southern Alberta, Canada, in 1921. D. torosus named by American-Canadian palaeontologist, Dale Alan Russell, in 1970. D. horneri named by Thomas Carr in 2017. Was originally thought to be a species of Gorgosaurus. Lived: 77 to 74 million years ago during the Campanian stage of the Late Cretaceous in what is now western Canada and the northwestern United States.
Today's "Dino of the Day!" was made famous by its appearance in Jurassic Park: Dilophosaurus.
Pronunciation: Die-lo-fo-sore-us. Meaning of name: "Two-crested lizard", in reference to the crest on its head. Species: D. wetherilli Size: 6 metres long, 2 metres tall and weighing around 400kgs. Family: Dilophosauridae. Diet: Carnivore. First fossils found: First discovered by a field party from the University of California Museum of Paleontology in the Kayenta Formation of northern Arizona in 1942. Named by American palaeontologist, Samuel Paul Welles, in 1970. Was originally thought to be a species of Megalosaurus. Contrary to popular belief, there's no evidence to suggest that Dilophosaurus had an extendable neck frill or used venom to kill its prey. Lived: 193 million years ago during the Sinemurian stage of the Early Jurassic in what is now the southwestern United States.
Today's "Dino of the Day!" is one of the longest dinosaurs known from a complete skeleton: Diplodocus.
Pronunciation: Di-plod-oh-cus. Meaning of name: "Double beam", in reference to the double-beamed chevron bones located in the underside of the tail. Species: D. hallorum, D. carnegie Size: Depending on species, measured between 24 and 33 metres long, 6 metres tall and weighing between 11 and 15 metric tonnes. Family: Diplodocidae. Diet: Herbivore. Fed on both high and low-growing vegetation. First fossils found: Known from several specimens, the first of which was discovered by Benjamin Franklin Mudge and Samuel Wendell Williston in the Morrison Formation of Colorado in 1877. D. carnegie named by American palaeontologist, John Bell Hatcher, in 1901. D. hallorum named by David Gillette in 1991. Footprints have also been discovered. Lived: 154 to 152 million years ago during the Kimmeridgian stage of the Late Jurassic in what is now the mid-western United States.
Pronunciation: See-rat-oh-sore-us Meaning of name: "Horned lizard", in reference to the stumpy horn on its snout. Species: C. nasicornis, C. dentisulcatus, C. magnicornis. It's possible there may be other species. Size: Estimated to have measured between 6 and 7 metres long, 2 metres tall and weighing up to 700kgs. Family: Ceratosauridae. Diet: Carnivore. First fossils found: Known from several specimens, the first of which was discovered in the Morrison Formation of Colorado by farmer Marshall Parker Felch during the early 80's. C. nasicornis named by American palaeontologist, Othniel Charles Marsh, in 1884. C. dentisulcatus and C. magnicornis named in 2000. Lived: Depending on species, from 157.3 to 145 million years ago during the Kimmeridgian and Tithonian stages of the Late Jurassic in what is now Portugal and the western United States. May also have lived in what is now Switzerland, Tanzania and Uruguay.
