I wander what damage the collectors made to Irritator ? Perhaps they did a hack job at digging it up.

My favourite Sauropod and one of the tallest dinosaurs of the Late Jurassic: Name: BrachiosaurusPronunciation: 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 9-metre-long neck.

Family: Brachiosauridae Diet: Herbivore 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.

Name: DilophosaurusPronunciation: Di-lo-fo-sore-us Meaning of name: "Two-crested lizard", in reference to the v-shaped crest on its head. Species: D. wetherilliSize: 6 metres long, 2 metres tall and weighing around 400kgs.

Over the years, palaeontologists have named hundreds of different dinosaurs, but this one was the first herbivorous dinosaur to be officially named, way back in 1825. Name: IguanodonPronunciation: 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 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 thirty-eight individuals. These skeletons are now on display at the Royal Belgian Institute of Natural Sciences. 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.

Family: Chasmosaurinae (a sub-family of Ceratopsidae) Diet: Herbivore First fossils found: Known from several specimens, the first of which were discovered by American palaeontologist, Charles Hazelius Sternberg in the Fruitland Formation of New Mexico, in 1921. Named by American palaeontologist, Henry Fairfield Osborn, in 1923. Lived: 76 to 73 million years ago during the Campanian stage of the Late Cretaceous in what is now the southwestern United States.

Here's a tiny dino with a big name: Name: HeterodontosaurusPronunciation: Het-er-o-dont-o-sore-us Meaning of name: "Different-toothed lizard", because it had three different kinds of teeth. Species: H. tuckiSize: 90cm long, 50cm tall and weighed between 2 and 10kgs. Family: Heterodontosauridae Diet: Herbivore First fossils found: Known from several specimens, the first of which was discovered by a British-South African expedition to South Africa during the early 1960's. Named by English palaeontologist, Alan Jack Charig and South African palaeontologist, Alfred Walter Crompton, in 1962. Most dinosaurs only have one type of tooth, but Heterodontosaurus had three: incisor-like teeth at the front of the jaws, a pair of tusks in the middle and grinding cheek teeth at the back. Lived: 200 to 190 million years ago from the Hettangian stage through to the Pliensbachian stage of the Early Jurassic in what is now South Africa.

This dino is one of T-Rex's closest relatives: Name: DaspletosaurusPronunciation: Das-plee-toe-sore-us Meaning of name: "Frightful lizard" Species: D. torosus, D. horneri, possible there may be a third species. 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.

Name: ProtoceratopsPronunciation: Pro-toe-seh-rah-tops Meaning of name: "First horned face" Species: P. andrewsi, P. hellenikorhinusSize: 1.8 metres long, 0.7 metres high and weighing around 83kgs. Family: Protoceratopsidae Diet: Herbivore First fossils found: Known from several individuals, the first of which was discovered by photographer, James Blaine Shackelford, during an American expedition to Mongolia's Gobi Desert in 1922. P. andrewsi named by American palaeontologists, William King Gregory and Walter Willis Granger, in 1923. P. hellenikorhinus named in 2001. A remarkable fossil discovered in 1971 shows a Protoceratops locked in battle with a Velociraptor. It's believed they were either buried by a collapsing sand dune or surprised by a sandstorm. Unlike later Ceratopsians, Protoceratops didn't have horns. Lived: 75 to 71 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous in what is now northern China and southern Mongolia.

This dino is one of longest known from a complete skeleton, its tail alone measuring eight metres long. Name: DiplodocusPronunciation: Di-plod-oh-cus Meaning of name: "Double beam", in reference to the double-beamed chevron bones located in the underside of the tail.

This is the largest and most well-known Theropod from the Late Jurassic: Name: AllosaurusPronunciation: Al-low-sore-us Meaning of name: "Different lizard" Species: A. fragilis, A. europaeus, A. jimmadseniSize: Depending on species, measured between 8 and 12 metres long, 3 metres tall and weighing around 2.5 metric tonnes. Family: Allosauridae Diet: Carnivore First fossils found: Known from several specimens, the first of which was a fragmentary specimen discovered in Colorado in 1869. First named Antrodemus ("Chamber-bodied") by American palaeontologist, Joseph Leidy, in 1870. A second fragmentary specimen named Allosaurus by American palaeontologist, Othniel Charles Marsh, in 1877. In 1920, it was suggested by another palaeontologist, Charles Whitney Gilmore, that Allosaurus and Antrodemus may be the same animal. During the early 1960's, thousands of fossils were discovered at the Cleveland-Lloyd Quarry in Utah and, after studying the bones, it was decided that Allosaurus would be the official name because Antrodemus was based on poor material. Lived: Depending on species, lived between 155 and 145 million years ago during the Kimmeridgian and Tithonian stages of the Late Jurassic in what is now the western, south central, midwestern and southwestern United States.
