CeratosaurusCeratosaurus ˌsɛrətoʊ-ˈsɔːrəs (from Greek κέρας/κέρατος, keras/keratos meaning "horn" and σαῦρος sauros meaning "lizard") was a carnivorous theropod dinosaur that lived in the Late Jurassic period (Kimmeridgian to Tithonian ages). The genus was first described in 1884 by American paleontologist Othniel Charles Marsh based on a nearly complete skeleton discovered in Garden Park, Colorado, in rocks belonging to the Morrison Formation. The type species is Ceratosaurus nasicornis.
Field Museum of Natural HistoryThe Field Museum of Natural History (FMNH), also known as The Field Museum, is a natural history museum in Chicago, Illinois, and is one of the largest such museums in the world. The museum is popular for the size and quality of its educational and scientific programs, and its extensive scientific specimen and artifact collections. The permanent exhibitions, which attract up to 2 million visitors annually, include fossils, current cultures from around the world, and interactive programming demonstrating today's urgent conservation needs.
American Museum of Natural HistoryThe American Museum of Natural History (abbreviated as A.M.N.H) is a natural history museum on the Upper West Side of Manhattan in New York City. Located in Theodore Roosevelt Park, across the street from Central Park, the museum complex comprises 20 interconnected buildings housing 45 permanent exhibition halls, in addition to a planetarium and a library.
AmphicoeliasAmphicoelias (ˌæmfᵻˈsiːliəs, meaning "biconcave", from the Greek ἀμφί, amphi: "on both sides", and κοῖλος, koilos: "hollow, concave") is a genus of herbivorous sauropod dinosaur that lived approximately 150 million years ago during the Tithonian (Late Jurassic Period) of what is now Colorado, United States. Amphicoelias was moderately sized at about in length and in body mass, shorter than its close relative Diplodocus. Its hindlimbs were very long and thin, and its forelimbs were proportionally longer than in relatives.
TornieriaTornieria ("for Tornier") is a genus of diplodocid sauropod dinosaur from the Late Jurassic in Lindi Region of Tanzania. It has a convoluted taxonomic history. In 1907, German paleontologist Eberhard Fraas who was working the Tendaguru Beds in German East Africa (presently Tanzania), discovered two sauropod specimens at a single site ("Quarry A"). The two individuals, designated "Skeleton A" and "Skeleton B", each represented a different sauropod species. In 1908 he named these respectively Gigantosaurus africanus ("African giant lizard") and G.
SaurischiaSaurischia (sɔːˈrɪskiə , meaning "reptile-hipped" from the Greek (σαῦρος) meaning 'lizard' and (ἴσχιον) meaning 'hip joint') is one of the two basic divisions of dinosaurs (the other being Ornithischia), classified by their hip structure. Saurischia and Ornithischia were originally called orders by Harry Seeley in 1888 though today most paleontologists classify Saurischia as an unranked clade rather than an order.
NanosaurusNanosaurus ("small or dwarf lizard") is the name given to a genus of neornithischian dinosaur that lived about 155 to 148 million years ago, during the Late Jurassic-age. Its fossils are known from the Morrison Formation of the south-western United States. The type and only species, Nanosaurus agilis, was described and named by Othniel Charles Marsh in 1877. The taxon has a complicated taxonomic history, largely the work of Marsh and Peter M.
GiraffatitanGiraffatitan (name meaning "titanic giraffe") is a genus of sauropod dinosaur that lived during the late Jurassic Period (Kimmeridgian–Tithonian stages) in what is now Lindi Region, Tanzania. It was originally named as an African species of Brachiosaurus (B. brancai), but this has since been moved to its own genus. Giraffatitan was for many decades known as the largest dinosaur but recent discoveries of several larger dinosaurs prove otherwise; giant titanosaurians appear to have surpassed Giraffatitan in terms of sheer mass.
