First the earth more than 4,000 million years ago, and developed since that time many different life forms have become extinct and later. During this time various rock layers were in the ground (for example, sediments fall to the ground laid rivers, lakes and seas), and often traces of life forms of the past in the rocks as fossils remained. Scientists have the layers of rock different names given according to the different eras of Earth's history. The erain which the dinosaurs lived, sometimes popularly called the "age of reptiles," is known as the Mesozoic known and spans the period between 248 million years old and 65 million years old. The Mesozoic is divided into three periods (the Triassic, Jurassic and Cretaceous), and at the end of the Cretaceous period (divided, at the beginning of the subsequent Tertiary period), all the dinosaurs, as well as numerous other marine and land animalsSuddenly went out.

Many explanations have been proposed for the extinction of the dinosaurs, from a nearby supernova (an exploding star, which would be the earth exposed to intense radiation) have, up to the mammals, dinosaurs' eggs, and from climate change to the newly developed angiosperms (flowering plants, plants) hallucogenic with implications for dinosaurs. Not all are equally plausible explanations - just think to remember that what the explanation for the extinction ofDinosaurs, we must also include an explanation that the mass extinction of all other creatures, who died at the same time to find cover.
