Dinosaurs Extinction (the Truth)

Sunday, June 14, 2015

The extinction of all dinosaurs was not caused by a falling asteroid. This affirmation is solidly based on one single fact; the fossil remains of different species of dinosaurs have not been found in one single geological stratum, but in different ones. For example, millions of years before Tyrannosaurus rex arrived, Brontosaurus was already extinct! The latter had arisen on the surface of the planet about 150 millions years ago, having flourished in the late Jurassic period of the Mesozoic era; while Tyrannosaurus rex's fossil remains have been discovered in the late Cretaceous stratum. Thus, if the theory that supports that the extinction of all dinosaurs was caused by the collision of a falling asteroid against the Earth was true, then the fossil remains of every species of dinosaurs would have been found in one single geological layer. So, the question is: what caused the extinction of Brontosaurus and all the other creatures that preceded it?

The existential periods of all the giant lizards overlap and their remains have been found in different geological strata. Why does the "falling asteroid" theory have more media and Hollywood support? Because it sells. You can shoot a movie and make millions of dollars based on a theory that sounds catastrophic and "spectacular". So, greediness goes against scientific objectivity. It is true that the Earth has been hit by outer space objects throughout its history, though, but the meteorite that impacted against the Yucatan peninsula in the late Cretaceous did not cause a cataclysmic event strong and intense enough to wipe out all the dinosaurs at once; for fossil bones of Hadrosaurus, Anklyosaurus, and even Tyrannosaurus were found in the Paleocene stratum. Their existence overlapped with the emergence of warm-blooded creatures like birds and mammals. The Paleocene period of the Cenozoic era follows the Cretaceous.

Dust and sediments caused by a violent natural event settle much faster than many think. For example, the eruption of Mount St Helens in Washington State in 1980 is calculated to be event stronger in liberation of energy as when the Earth was hit by a meteorite on the Yucatan peninsula; however the volcano eruption ash spread only throughout six States and it settled down in less than six weeks. For Hollywood and cable TV programs, it is very boring to say that all dinosaurs have gradually became extinct due to a slow and steady cooling of the Earth temperature and biological circumstances, such as fighting for the survival, but for scientists it should not. Wake up! Break out of the shell!
