“Scientists have been trying to explain the extinction of dinosaurs for a long time. First it was a massive asteroid impact, which hurled vast clouds of dust into the stratosphere, causing sunlight to be blocked out and a resultant worldwide winter. However,the latest twist is that the asteroid now believed to have struck parts of the Gulf of Mexico heated large amounts of water to 50°C, much hotter than present oceans, and triggered giant hurricanes with near supersonic winds that also hurled vast quantities of debris into the stratosphere.”
The large asteroid which struck the Earth forming a 240 kilometer crater in what is now the Yucatan Peninsula in Mexico. This impact would have caused - among other disasters - several extremely cold months or years because of dust in the atmosphere. This theory was proposed in 1980 by physicist Luis Alvarez and his son Walter Alvarez, a geologist.
Well to me at least these theories are just that,theories.Now on the other hand,the image on this dinosaur mousepad is more akin to my views on what happened to the critters.Add to this,the slogan on the T shirt,and I think that together we've we've put forward a theory that's as plausible as all the Paleontology mumbo jumbo and the Mexican meteor strike hunch.
