Everest Summit Rocks Hold 3 Marine Fossil Types Just 6 Meters Below Peak

Summary
Rock samples collected about 6 meters below Mount Everest’s summit contain fossil fragments of trilobites, crinoids and ostracods in the Qomolangma Formation limestone.
Ordovician marine sediments later became summit rock after India collided with Eurasia, closing the Tethys Ocean and thrusting those layers into the Himalaya.
The evidence comes from long-established geological work, including a 2005 paper, not a fresh one-off discovery; the fossils are often fragmented or recrystallized rather than obvious surface specimens.
That makes Everest’s top a tectonic record as well as a geographic extreme, preserving traces of an ancient sea nearly 9 kilometers above present sea level.
