Most of us has this misconception that the age of the dinosaurs was a period where every dinosaurs wandered. Dinosaur species were separated by both time and geography. T-Rex evolved much later than Stegosaurus. But most importantly, dinosaurs lived on the other side of the galaxy. Everything within our galaxy is spinning around black hole. Stars nearer to the center spins faster than those in the outer regions. Our Solar System revolves around the black hole just like Earth revolves around the Sun. We are moving approximately 28,000 light years away from the galactic center. On the basis of position in galaxy, an orbit is completed about 250 million Earth Years. Dr. Jesse Christiansen from NASA exoplanet Science Institute mapped out dinosaur evolution through the galaxy's rotation. She claims that the astronomical timescales matches up with the archaeological timescales. Dinosaurs were just emerging when our Solar System was at it's current point in the galaxy(Mesozoic Era). The Triassic, Jurassic and Cretaceous periods falls within the Mesozoic Era. All the continents were merged together in a single supercontinent known as Pangea during the Triassic period. 65 million years ago, dinosaurs became extinct on Cretaceous period(Cretaceous Paleogene Extinction or ckt extinction). It is claimed to have caused due to the impact of a massive comet 10-16 kms wide. The Permian Triassic Extinction event known as the Great Dying occurred around 252 million years ago eliminating 96% of all marine species and 70% of all terrestrial vertebrate species on Earth. Stegosaurus, Iguanodons and Giganotosaurus lived in the early Cretaceous period on the other side of the galaxy. T-rex lived 65 million years ago while Stegosaurus lived 83 million years ago from the T-rex. Let's consider the 230 million years into 1 calendar year. Dinosaurs evolved on January 1st and became extinct on 3rd week of September. Considering the same scale, humans evolved on December 31st. Some think of birds and lizards as one line descendants of dinosaurs.
