PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Gigantoraptor (Gigantoraptor erlianensis) pair in dense forest, artwork. Gigantoraptor was a large dinosaur that lived 85 million years ago, during the Late Cretaceous Period. It grew to a height of 8 metres and weighed 1400 kilograms. It belonged to the Oviraptoridae group of dinosaurs which had bird-like beaks and feathers. Gigantoraptor was bipedal. It had long, thin hindlimbs and shorter forelimbs with large, sharp claws, which suggested it was a fast running predator. It is thought that modern day birds evolved from feathered dinosaurs.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Kentrosaurus dinosaur, computer artwork. This 4-metre-long stegosaurid dinosaur is known from fossils discovered in Tanzania in the period 1910 to 1912. The fossils date from the Late Jurassic period, 145 to 160 million years ago. This dinosaur was herbivorous, feeding on plants and other vegetation. It is thought that the spines on its back and tail were used to defend against predators.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Monolophosaurus dinosaur. Computer artwork of a Monolophosaurus, a carnivorous dinosaur that lived in the Late Jurassic Period (150-135 million years ago). It was named for the single crest on top of its skull. The area that Monolophosaurus was found, in Xinjiang, China, showed signs of water, making it possible that this dinosaur lived on lake or ocean shores.

Formerly known as Diceratops, this horned herbivorous dinosaur is known from fossils discovered in 1868 in Wyoming, USA. It dates from the Late Cretaceous period, 65 to 100 million years ago. This dinosaur was herbivorous, feeding on plants and other vegetation.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Spinosaurus dinosaur, computer artwork. Spinosaurus lived in what is now northern Africa during the late Cretaceous period (95-80 million years ago). It was the longest carnivorous dinosaur, reaching a length of up to 16 metres. It also had a long crocodile-like head, and probably fed on fish. The sail on its back might have been used for temperature regulation or in mating displays.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Suchomimus dinosaur, computer artwork. This bipedal spinosaurid dinosaur is known from fossils discovered in the Sahara in 1998. The fossils dates from the middle part of the Cretaceous period, 110 to 120 million years ago. This dinosaur, around 12 metres in length, was a predator and scavenger, feeding on fish and carrion. Its elongated mouth was similar to that of a crocodile.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Tarbosaurus dinosaur. Computer artwork of an Tarbosaurus, a large bipedal predator belonging to the same family as Tyrannosaurus Rex (Tyrannosauridae). Of all the tyrannosaurids, the Tarbosauryus has the smallest two-fingered forelimbs in relation to body size. It also weighed more than a ton and its mouth was equipped with dozens of large, sharp teeth and a unique locking mechanism in its lower jaw. It lived in Asia at the end of the Late Cretaceous Period (70-65 million years ago).

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Utahraptor dinosaur, artwork. Utahraptor ostrommaysorum are dromaeosaurs and thought to have been an extremely lethal group of dinosaurs because of the 'killer claws' on their feet. Utahraptor was the tallest of the dromaeosaurs which include Velociraptor and Dromaeosaurid. It measured 5-7 metres in length and weighed about 1 tonne. Utahraptors lived in what is now Utah, USA, in the Early Cretaceous Period (about 120 million years ago).

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Mammoth, prehistoric bone art. This image of a mammoth has been scratched onto a piece of mammoth's tusk. It was found in the cave of La Madeleine, Dordogne, France. This area was occupied by a prehistoric people called the Magdalenians, during the Upper Paleolithic period from 18,000 to 11,000 BC. Archaelogical research has shown that the Magdalenian diet consisted largely of meat often obtained from hunting big game.
