Dinosaurs the word by itself requires no introduction, the entire world is well aware of the past lives of the creatures that once lived on the planet and were credited to be the only lizards to have walked on straight legs unlike the modern lizards walking folded ones.
Crocodiles are the best and the closest known creatures that are known to live alongside these majestic animals and derive a significant amount of relevancy together.
We are still discovering new fossils every day, new discoveries are rapidly coming to the picture.
An impact from an asteroid that hit the ground in late Cretaceous period is the most important reason for the extinction of dinosaurs many scientists think that it may not be entirely correct as after effects can also be responsible for the disappearance of remaining ones.
The reason that lots of species disappeared along before the crash may be due to a wide spread of some dinosaur plague or could be due to the environmental changes. Though it is not certain which one is the correct, In the present days, a few of the fossils are found having radioactive properties in them especially the fossil from the late Cretaceous period.
Fossil evidence indicates that brachiosaur aces existed long before the first T-Rex ever came into existence, and it is also a huge misconception about t-rex it was the largest carnivore. In fact, it was sixth in the position according to size compared to another colossal meat eaters like mapusaureus, carcharodontosaurians, giganotosaurus, saurophaganax and Spinosaurus although the new discoveries suggest that t-rex was the most well designed killing machine but still was not greatest.
Discoveries of more titanic giants are still going on it is a huge misconception that people believe that all flying reptiles were dinosaurs, but they belonged to a distinct group of reptiles called pterosaurs.
Between those above many weird-looking and eccentric dinosaurs were discovered such as therizinosaurs the most strangest of all and pterosaur Hatzegopteryx a reptile that managed to fly. Primary groups were the sauropod, theropod, ornithopod, ceratopsian, stegosaur, ankylosaur; duck build was later classified and extensive researches performed to comprehend the seeds of evolution: our ancestors.
