Dinosaurs used to be the dominant vertebrate animals of our ecosystem. Under the phylogenetic taxonomy, dinosaurs are classified as sole descendants of the most current ancestors of modern birds and Triceratops. It is also suggested that dinosaurs can be classified as the descendants of the most current ancestor of the iguanodon and megalosaurus. This is since these are two of the three main genres quoted by Richard Own, particularly when he distinguished the dinosaurian classification.

Although T-Rex is the most popular dinosaur, there are actually various types of dinosaurs that lived long ago. In fact, there are now several facts and information about the most common dinosaurs. Many books about paleontology and archeology give a lot of information about the different species that existed. Facts about usual dinosaurs can also be found in the Internet. There is a wide information and detail about them. In fact, pictures of the most usual dinosaurs are also indicated so that even kids will have a general idea about their appearance.

There are also facts regarding the extinction of dinosaurs. These facts provide concepts on how dinosaurs became extinct in our planet 65 million year ago. Amongst other theories, the theory about a comet that hit the Earth and created massive mayhem such as clouds of smoke that lasted for months and deprivation of vegetation among others, is the one most believed by scientists. Up to now, paleontologists and archeologists study the fossils and remains of dinosaurs they found in order to shed light to the theories that pertain to their extinction centuries ago.

Facts about the bones of dinosaurs are complied and written in books by specialists that specialize in dinosaur bones. Numerous facts about bones of dinosaurs can also be found in museums. Archeologists study any dinosaur bone gathered from various parts of the word in order to know more about their kind and lifestyle. Due to the presence of fossils, the kinds of dinosaurs where revealed and man can now say that dinosaurs really existed some time in the past even before the birth of mankind.

Thus, facts about dinosaur eggs usually concentrate on what type of dinosaur they come from and the appearance of these eggs. The texture of the eggs can be verified by specie. It is interesting to know that these eggs follow a pattern when it comes to its eggshells. This pattern of eggshells enlightens us with what kind of dinosaur species it came from. The eggs of dinosaurs vary in shapes and sizes. Studying these eggs can help us analyze further these interesting species that once ruled the earth.

Dinosaurs were real and live animals that lived in most regions of the world and were completely wiped out 65 million years ago. The cause of their extinction is still debated but most of the researchers agree that when alive, the dinosaur dominated the wilds. Their footprints have found in rock, as well as some eggs rooted in them. Most of the bigger dinosaur specimens have now been collected and displayed in larger museums.

Most of the researchers around the world agree that dinosaurs are one of the larger species that lived in the Age of Reptiles, which was about more than 200 million years ago. It is estimated that the dinosaur age lasted for some 165 million years. During this time period, many types of dinosaurs roamed the wilds. Researchers have successfully come to know the variety of species of dinosaurs that existed during this time. This is done by the study of fossils of dinosaur bones being found out at different places of the world. However, many dinosaurs will never be discovered. This is due to the reason that only very few dinosaur bones are in reality fossilized through the delicate and temperamental process. In such a case, the tiniest dinosaurs and the largest will most likely be a mystery for the rest of time. Till this time, many dinosaur bones have been discovered only a few complete skeletons have ever been found. When scientists try to assemble a skeleton from bones, most of the process involves a large amount of assessment between size and morphology of other bones.

The fossilized dinosaur bones that have been unearthed from different parts of the world have helped us to know more about the mystifying creatures. The fossils of dinosaur bones serve as evidences that most dinosaurs had large bodies. Even the tiniest dinosaurs were bigger than anything else in their ecosystem and the largest dinosaur bones ever found indicate animals on a scale never seen in modern times. Dinosaurs bigger than the 38 ft tall Brachiosaurus found in Tanzania sometime between 1907-1912 have only been indicated by isolated bones.

Dinosaur bones can expose important information about the behavior of the dinosaur in its living environment. Time and again, computer simulations are employed to comprehend how a dinosaur with certain bones might have moved. These simulations compare the bones of the dinosaur with bones from more modern animals and then reconstruct the kinetics of movement based on the shapes of the bones. Because dinosaurs are thought to be more closely related to animals like birds and crocodiles rather than mammals, behaviors from these animals can be used to estimate dinosaur behavior. The analysis of bones used for movement, or Biomechanics, gives scientists information as to how quickly dinosaurs moved, if some dinosaurs could swim, and reveals whether ideas like sonic booms created by the diplodocid tail are fact or fiction.
