Fossils Near Mount Everest Summit: Mount Everest is known as the tallest mountain in the world. But scientists have made a surprising discovery there. Researchers have found marine fossils that are about 450 million years old on the mountain. These fossils were discovered more than 13,000 feet above sea level.
The fossils show that the top of Everest was once part of an ancient ocean floor. Long before the mountain existed the area was covered by a warm tropical sea. Inside the rocks scientists found remains of ancient sea animals such as crinoids, trilobites, cephalopods and brachiopods. These creatures once lived in shallow ocean water millions of years ago.

The fossils were discovered in rocks known as the Qomolangma Limestone. This type of rock forms in marine environments. Over a very long time the remains of sea animals were buried in ocean mud and sand. Later those materials slowly turned into solid rock. Today those same rocks are found near the summit of Everest.
The Ancient Tethys Ocean
Long ago a huge ocean called the Tethys Ocean covered much of the region where the Himalayas stand today. The sea was full of life and many marine animals lived there. When these creatures died their bodies sank to the ocean floor.
Layer after layer of sediment slowly covered the remains. As time passed the sediments hardened into limestone rock. These rocks eventually became part of the mountain that we now call Everest.
This is why scientists can still find fossils of sea animals so high above the ground today.
How the Himalayas were Formed?
The reason these ocean fossils ended up on the highest mountain on Earth is because of movement in the Earth’s crust. Around 50 million years ago the Indian Plate crashed into the Eurasian Plate.
The collision pushed huge layers of rock upward. These layers included the old marine sediments from the ancient ocean. Over millions of years the pressure lifted them high into the sky and formed the Himalayas.

This process is still happening today. Scientists say the Himalayas continue to grow slowly each year. The mountains rise by a little more than one third of an inch every year because the two tectonic plates are still pushing against each other.
Evidence for Continental Drift
The discovery of sea fossils on Everest also supports an important scientific idea called continental drift. This theory was first proposed in 1915 by the German scientist Alfred Wegener.
At the time many scientists did not believe continents could move. But discoveries like the fossils on Everest helped prove that the Earth’s surface changes over time. Continents slowly move and collide which can create new mountains.
