We’ve never heard of this before, but it seems that some people don’t understand why marine fossils can be found at the summit of Mount Everest.
The limestone sedimentary rock known as the “Qomolangma Limestone” is located at the summit. Many fossilized marine animals from the Ordovician Period, which lasted from 488.3 million to 443.7 million years ago, can be found inside. These fossils, which include trilobites, brachiopods, ostracods, and crinoids, are discovered all over the Himalayas.
It is not proof of a massive flood that engulfed the entire planet, as one Facebook user asserted in screenshots uploaded to the Fraudulent Archaeology Wall of Shame Facebook group. There have been previous similar claims that were equally false. Indeed, it provides proof of plate tectonics.
The majority of sedimentary rocks are created by water erosion, which grinds up rocks over millions or thousands of years until they are compressed and undergo pressure-induced transformation into sedimentary rock. The rock at the top of Mount Everest was once underwater, as evidenced by the sedimentary rock and the existence of extinct marine life. It also indicates that the rock was raised more than 8,000 meters (26,200 feet) above sea level by some sort of event.
Plate tectonics is, of course, the explanation. Between 40 and 50 million years ago, the Eurasian and Indian continental plates collided to form the Himalayas and Everest.
“The Eurasian plate was partly crumpled and buckled up above the Indian plate but due to their low density/high buoyancy, neither continental plate could be subducted,” according to the Geological Society. “This caused the continental crust to thicken due to folding and faulting by compressional forces pushing up the Himalayas and the Tibetan Plateau.”
That explains why the world’s (almost) highest mountain contains marine fossils.
