Today's "Dino of the Day!" was discovered in my home state of Victoria and named after Australia's national airline: Qantassaurus.
Pronunciation: Kwan-tass-sore-us. Meaning of name: "Qantas lizard", after Qantas, Australia's national airline. Species: Q. interpidus. Size: Unknown due to a lack of fossils. Family: Uncertain. Diet: Herbivore. Fed on low-growing vegetation. First fossils found: Known only from a few jaw fragments discovered in the Wonthaggi Formation of southeastern Victoria, Australia, in 1996. Named by Australian palaeontologists, Tom Rich, and his wife, Patricia, in 1999. Lived: 115 million years ago during the Aptian stage of the Early Cretaceous in what is now southern Australia.
Today's entry is a tiny Pterosaur from Germany: Anurognathus
Pronunciation: An-yu-rog-na-thus Meaning of name: "Without tail jaw". Species: A. ammoni Wingspan: 50cm. Estimated weight of around 40g. Family: Anurognathidae. Diet: Insectivore. First fossils found: Known only from two almost-complete skeletons, the first of which was discovered in the Altmühltal Formation of southeastern Germany in 1923. Named in the same year by Ludwig Döderlein. Lived: 152.1 to 145 million years ago during the Tithonian stage of the Late Jurassic in what is now southeastern Germany.
Today's "Dino of the Day" is my favourite Dromaeosaurid: Deinonychus
Pronunciation: Die-non-e-cus Meaning of name: "Terrible claw", in reference to the large, sickle-shaped claw on the second toe of each foot. Species: D. antirrhopus Size: 3.5 metres long, 1.5 metres tall and weighing between 70 and 100kgs. Family: Dromaeosauridae. Diet: Carnivore First fossils found: Known from several specimens, the first of which was discovered by American palaeontologist, Barnum Brown, in southern Montana in 1931. Named by American palaeontologist, John Harold Ostrom, in 1969. Many palaeontologists consider Deinonychus to have been a pack hunter due to frequent discoveries of relatively-complete Deinonychus skeletons close to skeletons belonging to the large herbivore, Tenontosaurus. Considering the major differences in size and weight, it's unlikely a solitary Deinonychus would have been able to kill an adult Tenontosaurus. Lived: 115 to 108 million years ago during the Aptian and Albian stages of the Early Cretaceous in what is now the northwestern, south-central and western United States.
Today's "Dino of the Day!" is one of my favourite Hadrosaurs: Olorotitan.
Pronunciation: Ol-low-row-ti-tan. Meaning of name: "Titanic swan", in reference to its long neck. Species: O. arharensis Size: Between 8 and 12 metres long, 4 metres tall (up to 6 metres tall when standing upright) and weighing 3 metric tonnes. Family: Lambeosaurinae (a sub-family of Hadrosauridae) Diet: Herbivore. Fed on both high and low-growing vegetation. First fossils found: Known only from a single, almost-complete skeleton discovered in the Udurchukan Formation of Far Eastern Russia between 1999 and 2000. Named by Belgian palaeontologist, Pascal Godefroit, in 2003. This dino's most striking feature is the large, hollow, hatchet-like crest on the head which is thought to have been used for display and vocal communication. Lived: 67 to 66 million years ago during the Maastrichtian stage of the Late Cretaceous in what is now Far Eastern Russia.
Pronunciation: Hoo-die-sore-us Meaning of name: "Butterfly lizard". Species: H. sinojapanorum Size: Estimated to have measured around 32 metres long, 10 metres tall and weighing between 25 and 55 metric tonnes. Family: Mamenchisauridae. Diet: Herbivore. Likely fed on both high and low-growing vegetation. First fossils found: Known only from the fragmentary skeletons of two individuals discovered by a Chinese-Japanese expedition to the Kalazha Formation of Xinjiang Province, northwest China, in 1993. Named by Chinese palaeontologist, Dong Zhiming, in 1997. Lived: Uncertain, but is thought to have lived from 161 to 145 million years ago during the Oxfordian, Kimmeridgian and Tithonian stages of the Late Jurassic in what is now northwest China.
