4 Paul Iacovella/OLMC/yr4/2009 Animals Allosaurus This fierce two legged carnivore lived in the late Jurassic period. It inhabited the plants, and normally hunted alone. It would hunt in groups to tackle the largest prey. It was approximately 12 meters long, five meters high and up to three tonnes. Here is a list of dinosaurs for you.

5 Brachiosaurus lived in the middle to late Jurassic period, about million years ago, near the middle of the Mesozoic Era, the Age of Reptiles. Some dating estimates have Brachiosaurus surviving until 140 million years ago, during the dawn of the Cretaceous period. Camptosaurus (meaning "bent lizard") was a plant-eater from the late Jurassic period (about 156 to 145 million years ago) that looked a lot like Iguanodon. It was a heavy ornithischian dinosaur that was about feet (5-7 m) long and 3-4 feet (1 m) high at the hips, weighing roughly 2,200 pounds (1000 kg). It had a long snout, hundreds of teeth and a horny beak. Its legs were longer than its arms; it had four-toed feet and five-fingered arms, all with hooves. It could walk on two or four legs, it probably went on all four to graze for low-lying plants. Dicraeosaurus had a large head with a relatively short and wide neck. It also lacked the whiplash tail that other diplodocids had. It was smaller, at only reached 41 feet (12 m) in length. It gets its name, which means two-forked lizard, from the spines that came from the vertebrae. They were not straight as in some members of the family. Each one was Y shaped, like a fork. These spines also provided muscle attachment points it lived in the late Jurassic period.

6 Eustreptospondylus ("well-curved vertebra", in reference to the arrangement of the spine in the original fossil) was a genus of megalosaurid dinosaurs from the Callovian stage of the Middle Jurassic period (165 to 161 million years ago) in southern England, at a time when Europe was a series of scattered islands (due to tectonic movement at the time which raised the sea-bed and flooded the lowland). The only known specimen of Eustreptospondylus may not be fully grown, and was about 4.63 metres (15.2 ft) long. It was carnivorous, bipedal and had a stiffened tail. It was a typical theropod, with powerful hind limbs, erect posture and small forelimbs. Fruitadens is a genus of heterodontosaurid dinosaur. The name means "Fruita tooth", in reference to Fruita, Colorado (USA), where its fossils were first found. It is known from partial skulls and skeletons from at least four individuals of differing biological ages, found in Tithonian (Late Jurassic) rocks of the Morrison formation in Colorado. Fruitadens is the smallest known ornithischian dinosaur, with young adults estimated at 65 to 75 cm (26 to 30 in) in length and 0.5 to 0.75 kg (1.1 to 1.7 lb) in weight. It is interpreted as an omnivore and represents one of the latest-surviving heterodontosaurids

7 Paul Iacovella/OLMC/yr4/2009 Giraffatitan, meaning giraffe titan", is a genus of sauropod dinosaur that lived during the late Jurassic (kimmeridgian-Tithonian stages). It was originally named as an African species of Brachiosaurus (B. brancai). One of the largest animals known to have walked the earth, it has become one of the most famous of all dinosaurs. Heterodontosaurus (meaning "different toothed lizard") is a genus of small herbivorous dinosaur with prominent canine teeth which lived in the Early Jurassic of South Africa. It was similar to a hypsilophodont in shape, and ate plants, despite its canines. Heterodontosaurus is currently known from specimens of the SAFM (South African Museum) from South Africa. There are two known morphologies of this genus, the second of which is thought by some to represent a different species. The type species, H. tucki, is from the Upper Elliot Formation of the Hettangian age, around million years ago.

8 Iguanodon (pronounced / ɨˈɡ w ɑː nəd ɒ n/, meaning "Iguana tooth") is a genus of ornithopod dinosaur that lived roughly halfway between the first of the swift bipedal hypsilophodontids and the ornithopods' culmination in the duck-billed dinosaurs. Many species of Iguanodon have been named, dating from the Kimmeridgian age of the Late Jurassic Period to the Cenomanian age of the Late Cretaceous Period from Asia, Europe, and North America. However, research in the first decade of the 2000s suggests that there is only one well-substantiated species: I. bernissartensis, that lived from the Barremian to the early Aptian (Early Cretaceous) in Europe, between about 130 and 120 million years ago. Iguanodon's most distinctive features were its large thumb spikes, which were possibly used for defence against predators and foraging for food./ ɨˈɡ w ɑː nəd ɒ n/Iguanatoothgenus ornithopoddinosaurbipedal hypsilophodontidsduck-billedKimmeridgianageLate JurassicPeriodCenomanianLate Cretaceous AsiaEuropeNorth AmericaBarremianAptianEarly CretaceousEuropepredators Discovered in 1822 and described three years later by English geologist Gideon Mantell, Iguanodon was the second dinosaur formally named, after Megalosaurus. Together with Megalosaurus and Hylaeosaurus, it was one of the three genera originally used to define Dinosauria. A large, bulky herbivore, Iguanodon is a member of Iguanodontia, along with the duck-billed hadrosaurs. The taxonomy of this genus continues to be a topic of study as new species are named or long-standing ones reassigned to other genera.EnglishgeologistGideon MantellMegalosaurusHylaeosaurusDinosauriaherbivoreIguanodontiahadrosaurstaxonomy Paul Iacovella/OLMC/yr4/2009

9 Jinfengopteryx (from Jinfeng, 'golden phoenix', the queen of birds in Chinese folklore, and Ancient Greek πτερυξ pteryx, meaning 'feather') is a genus of 55 cm (2 ft) long maniraptoran dinosaur. It was found in the Qiaotou member of the Huajiying Formation of Hebei Province, China, and is therefore of uncertain age. The Huajiying Formation underlies the more well-known Early Cretaceous Yixian Formation, so the Formation is either Early Cretaceous or Late Jurassic. Jinfengopteryx was preserved with extensive impressions of pennaceous feathers, but it lacks flight feathers on its hind legs, which are present in related dinosaurs such as Pedopenna.

It also preserves several small, oval structures that are reddish yellow in color. These may be the remains of eggs, or nuts/seeds that the dinosaur had eaten. Paul Iacovella/OLMC/yr4/2009 Kentrosaurus (meaning "pointed lizard"; pronounced / ˌ k ɛ tr ɵˈ s ɔ rəs/ KEN-tro- SAWR- ə s, from the Greek kentron/κεντρον, meaning "point" or "prickle", and sauros/σαυρος meaning 'lizard', [1] is a genus of stegosaurid dinosaur from the Late Jurassic of Tanzania, related to the better-known Stegosaurus of North America. Its fossils have been found in the Tendaguru Formation, dated to the Kimmeridgian stage, between about ± 4 Ma and ± 4 Ma (million years ago). / ˌ k ɛ tr ɵˈ s ɔ rəs/KEN-tro- SAWR- ə sGreek [1]genusstegosauriddinosaurLate JurassicTanzaniaStegosaurusNorth AmericaTendaguru FormationKimmeridgianMa This 4 meter long stegosaurian was described by in Like Stegosaurus, Kentrosaurus had a double row of plates running down its spine.

10 Lamplughsaura is a genus of saurischian dinosaur from the Sinemurian-age (Early Jurassic) Dharmaram Formation of India, between 196 to 190 million years ago. The type species is L. dharmaramensis. It is known from several partial skeletons of a large quadrupedal animal up to 10 meters (33 ft) long, and was either a basal sauropod or, less likely, a more basal sauropodomorph.
