Introducing Tyrannosaurus Rex Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex, commonly abbreviated to T. rex, is one of the most well-represented of the large theropods. Wikipedia Scientific name: Tyrannosaurus Higher classification: Tyrannosaurini Rank: Genus |
Physical Characteristic Walked on two legs, balancing its huge head with a long and heavy tail that sometimes contained over 40 vertebrae. Measured up to 13m (42ft) in length, 4m (13ft) at the hip and could weigh up to 7 tons! The skull measured up to 1.5m (5ft) long. The largest tooth of any carnivorous dinosaur found to this date is that of a T-Rex. It is estimated to have been around 30cm (12in) long when including the root.When Tyrannosaurus rex hit around the age of 14 its body size would increase rapidly, putting on around 600kg (1300lb) a year over the next 4 years. Had small arms that were extremely powerful and featured two clawed fingers. |

Where did he live Tyrannosaurus rex lived in an area of the Earth that now makes up western North America. He lived during the late Cretaceous period, about 85 million to 65 million years ago. T. rex lived in a humid, semi-tropical environment, in open forests with nearby rivers and in coastal forested swamps. The seasons were mild. |
Way of life T. rex was a meat-eater and was at the top of the food chain in its environment. It chased its prey and took huge bites of their flesh, mortally wounded the prey, then devoured it. Its huge jaws and powerful, clawed legs were its lethal weapons. T. rex's tiny arms may not have played much of a part in the kill. T. rex was a solitary hunter,may have fought other T Rex's, |

what type fossil been found petrified fossil mold and casts carbon film trace fossils preserved fossils |
how fossil formed An animal dies, its skeleton settles on the sea floor and is buried by sediment. The sediment surrounding the skeleton thickens and begins to turn to stone. The skeleton dissolves and a mould is formed. Minerals crystallise inside the mould and a cast is formed. The fossil is exposed on the Earth's surface. |

How scientists use fossils Fossils give us information about how animals and plants lived in the past. Some fossils are easy to identify and look like plants and animals alive today. So by studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. we can work out how and where they lived, |
Difference between these rocks Igneous rocks are formed when magma (or molten rocks) cool down, and become solid. Sedimentary rocks are usually formed by sedimentation of the Earth’s material, this normally occurs inside water bodies. Metamorphic rocks are formed when rocks change their original shape and form due to intense heat or pressure |

Why do sedimentary rocks contain fossils? Most fossils are found in sedimentary rock, which is the most common type of rock on earth. Sedimentary rocks form when particles of sediment are deposited by water or wind, and then hardened or consolidated through time. Shale, sandstone, and limestone are types of sedimentary rocks that often contain fossils. |
