Apparently, the name "Bent lizard" comes from the presumed flexibility of its unfused hip vertebrae. Unlike modern herbivores, Camptosaurus wasn't a fussy eater and was more than happy to eat whatever vegetation was available.
I bet he'd have a nibble if a Homo Erectus crossed his path.
Pronunciation: Salt-ah-sore-us. Meaning of name: "Salta lizard", after Salta Province, Argentina, where its fossils were discovered. Species: S. loricatus Size: 12 metres long, 3 metres tall and weighing between 6 and 7 metric tonnes. Family: Saltasauridae. Diet: Herbivore. Fed on both high and low-growing vegetation. First fossils found: Known from eggs and the partial skeletons of at least 5 individuals. First discovered by palaeontologists, José Fernando Bonaparte, Martín Vince and Juan C. Leal in the Lecho Formation of Salta Province, north-west Argentina between 1975 and 1977. Named by Mr. Bonaparte and Jaime E. Powell in 1980. Saltasaurus was the first Sauropod known to have had armour. Lived: 70 million years ago during the Maastrichtian stage of the Late Cretaceous in what is now Argentina.
Today's "Dino of the Day!" was the first herbivorous dinosaur to be officially named: Iguanodon.
Pronunciation: Ig-wah-no-don. Meaning of name: "Iguana tooth", because its teeth are similar in appearance to those of a modern Iguana. Species: I. bernissartensis, I. galvensis. Size: Between 10 and 13 metres long, 3 metres tall (up to 6 metres when standing upright) and weighing between 4 and 5 metric tonnes. Family: Iguanodontidae. Diet: Herbivore. Fed on both high and low-growing vegetation. First fossils found: Known from several specimens. The first specimen, a handful of teeth, was discovered by English doctor and palaeontologist, Gideon Mantell, in southeast England in 1822. Named by Mr. Mantell in 1825. First skeleton discovered in 1834. The largest-known discovery of Iguanodon fossils occurred in February 1878, when miners in the Bernissart coal mine came across the skeletons of 38 individuals. These skeletons are now on display at the Royal Belgian Institute of Natural Sciences in Brussels, Belgium. Lived: 126 to 122 million years ago during the Barremian and Aptian stages of the Early Cretaceous in what is now Belgium, Portugal, Germany, Spain and England.
A modern iguana-don. Size: 1.5 metres long. 3 kg in weight. Diet: Herbivore. Will do anything for a piece of melon or a strawberry Hobbies: Freeroaming, reading, social media, mischief
Today's "Dino of the Day!" is one of the most popular and most easily recognised dinos (and another of my personal favourites): Triceratops.
Pronunciation: Tri-seh-rah-tops. Meaning of name: "Three horned face", in reference to the horns on its head (a 1-metre-long horn above each eye and a shorter horn on the snout). Species: T. horridus, T. prorsus. Size: 9 metres long, 3.5 metres high and weighing between 6 and 12 metric tonnes. Family: Centrosaurinae (a sub-family of Ceratopsidae). Diet: Herbivore. Fed on low-growing vegetation. First fossils found: Known from several specimens, some of which are almost complete. The first specimen, a pair of brow horns attached to a skull roof, was discovered by George Lyman Cannon in Colorado in 1887. Was originally thought to be a prehistoric bison until a much more complete skull was discovered by American palaeontologist, John Bell Hatcher, in the Lance Formation of Wyoming, in 1888. T. horridus named by American palaeontologist, Othniel Charles Marsh, in 1889. T. prorsus named by Mr. Marsh in 1890. It's been suggested that Torosaurus may be a growth stage of Triceratops. There's also evidence that Triceratops was prey for T-Rex. Lived: 68 to 66 million years ago during the Maastrichtian stage of the Late Cretaceous in what is now western Canada and the western, northwestern and mid-western United States.
Today's "Dino of the Day!" is my no.1 favourite and the one that's usually the first to come to mind when the word 'dinosaur' is mentioned: T-Rex.
Pronunciation: Ty-ran-no-sore-us Meaning of name: "Tyrant lizard". The species name, rex, means "king" in Latin. Species: T. rex Size: Between 12 and 14 metres long, between 4 and 6 metres tall and weighing up to 10 metric tonnes. Family: Tyrannosauridae. Diet: Carnivore. First fossils found: Known from at least 50 individuals, including some almost-complete skeletons. First discovered by Arthur Lakes in Colorado in 1874. First partial skeleton discovered by American palaeontologist, Barnum Brown, in eastern Wyoming in 1900. Mr. Brown discovered a second partial skeleton in Montana in 1902. Named by American palaeontologist, Henry Fairfield Osborne, in 1905. "Sue", one of the largest and most complete specimens ever found, was discovered in South Dakota in August 1990 and currently stands in Chicago's Field Museum of Natural History. Whilst we don't know for certain if "Sue" is female, it's believed she died around the age of 28 and may have been killed by a parasitic infection from eating rotten meat. Lived: 67 to 66 million years ago during the Maastrichtian stage of the Late Cretaceous in what is now the western, northwestern and midwestern United States.
Today's "Dino of the Day!" is my favourite hadrosaur, Parasaurolophus.
Pronunciation: Pah-rah-sore-o-loe-fus. Meaning of name: "Near lizard crest". Species: P. walkeri, P. tubicen, P. cyrtocristatus. Size: Estimated to have measured around 10 metres long, 3 metres tall (up to 5 metres when standing upright) and weighing between 2 and 3 metric tonnes. Family: Lambeosaurinae (a sub-family of Hadrosauridae). Diet: Herbivore. Fed on both high and low-growing vegetation. First fossils found: Known from several skulls and partial skeletons. First discovered in Alberta, Canada, in 1920. P. walkeri named by Canadian palaeontologist, William Parks, in 1922. P. tubicen named by Swedish palaeontologist, Carl Wiman, in 1931. P. cyrtocristatus named by American palaeontologist, John Harold Ostrom, in 1961. This dino's most striking feature is the curved crest on the head. Skulls with different sized crests have been found and it's been suggested that the skulls with large crests belong to adult males and those with smaller crests belong either to adult females or juveniles. Currently, we don't know the function of the crest, but it may have been used to amplify the animal's calls or for a sexual display. The nasal passages run through the crest and this may have helped improve the sense of smell. Lived: 76.5 to 73 million years ago during the Campanian stage of the Late Cretaceous in what is now western Canada and the western and southwestern United States.
Today's "Dino of the Day!" is my favourite Sauropod and one of the largest-known prehistoric land animals: Brachiosaurus.
Pronunciation: Brak-he-o-sore-us. Meaning of name: "Arm lizard", because the front legs are longer than the hind legs to provide support for the long neck. Species: B. altithorax Size: Measured between 18 and 23 metres long, between 10 and 13 metres tall and weighing between 30 and 80 metric tonnes. Family: Brachiosauridae. Diet: Herbivore. Fed on high-growing vegetation. First fossils found: Known from several specimens, the first of which was discovered by American palaeontologist, Elmer Samuel Riggs, in the Morrison Formation of Colorado in 1900. Named by Mr. Riggs in 1903. Lived: 154 to 153 million years ago during the Kimmeridgian stage of the Late Jurassic in what is now the western United States.
