Dinosaurs was the dominant vertebrate animals of our ecosystem. Underneath the phylogenetic taxonomy, dinosaurs have been classified as sole descendants of the most current ancestors of modern birds and Triceratops. Additionally it is suggested that dinosaurs can be classified as the descendants of their most current ancestor of the iguanodon and megalosaurus. This is since these are two of the three chief genres quoted by Richard Own, especially when he distinguished the dinosaurian classification.
Hence, both classifications result to an identical set of animals being classified as dinosaurs. These classifications are published to coincide with the exact conception of dinosaurs which predated the Earth via using Phylogenetics.
Although T-Rex has become 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.

Amongst other theories, the theory about a comet that hit the Earth and created enormous mayhem such as clouds of smoke which 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 that they discovered to be able to shed light to the theories that pertain to their own extinction centuries ago.
Some extinction theories are thought to be primarily caused by environmental variables, multiple collision and asteroid collisions. Another theory about the extinction of dinosaurs is due to a gigantic volcanic explosion of the Earth’s super volcanoes.
