Fish Fossils Found In Mount Everest: How Did They Get There?
It’s not a great surprise if we find marine fossils inland areas around the world. After all, it is no secret that oceans covered the earth a very long time ago. But finding fish and ocean fossils in the tallest mountain range in the world came as a surprise to many. However, scientists and explorers did find fish and ocean fossils on Mount Everest, which stands 29,029 feet tall. They found remnants of creatures like ammonites, brachiopods, Trilobites, corals, and sponges in the Spiti Valley of the Himalayas. The fossils found show a marine environment that existed there millions of years ago. Let’s find out how these fish fossils ended up in such an unlikely place.
The Discovery of Fish Fossils in the Himalayas
The discovery of marine fossils in the Himalayas dates back to the early 20th century. Mountaineers scaling peaks like Mount Everest and Annapurna stumbled upon rocks embedded with fossilized sea creatures. Ammonites are notable among these fossils. Ammonites are extinct marine mollusks related to modern-day squid and octopuses. Apart from them, several other fossils of brachiopods (ancient marine arthropods), corals, and sponges (ancient creatures which typically grew in shallow marine waters) were also found.
In 1953, during Sir Edmund Hillary’s famous ascent of Mount Everest, he found fossilized sea creatures. He found those fossils in limestone formations near the summit. Later scientific expeditions confirmed these findings and uncovered additional marine fossils, including various species of fish. The fossils, embedded in sedimentary rocks, had once been part of the seabed of the ‘Tethys Ocean.‘ This was a massive body of water that existed between the Indian subcontinent and the Eurasian landmass.
“The fossils recorded around Mt Everest are Ordovician in age – that is, about 420 million years old – and formed under the ocean on the northern margin of India when it was still attached to Western Australia as part of the supercontinent Gondwana. About 130 million years ago, India drifted away from Gondwana and drifted northwards until it collided with Eurasia between 55-34 million years ago. This collision of continents resulted in massive uplift of the crust and the fossiliferous sedimentary rocks that formed part of northern India were thrust upwards by these colossal tectonic forces. These fossils are now found on top of Mt Everest (Qomolangma).”

Religious Interpretations: The Global Flood Theory
Proponents of the global flood theory, for instance, argue that these fossils are evidence of a cataclysmic flood. This is like the one described in the biblical story of Noah’s Ark. According to this theory, a massive flood once covered the entire Earth. This flood deposited marine life on land, including in mountain ranges like the Himalayas.
Supporters of this viewpoint to the rapid fossilization of aquatic organisms as evidence of a sudden, global event. They argue that the uplift of the mountains occurred after the floodwaters receded. They use this to explain why we find marine fossils at high altitudes today. While this interpretation is popular among certain religious groups, mainstream science does not support it.
Types of Marine Fossils Found
The types of fossils found in the Himalayas are critical to understanding Earth’s ancient marine ecosystems. Ammonites, which resemble modern-day nautiluses, are among the most common fossils that we discover in the region. These creatures thrived during the Mesozoic Era and became extinct around 66 million years ago during the Cretaceous–Paleogene extinction event.
In addition to ammonites, expeditions discovered fossils of fish, coral, and other marine life. These organisms lived in the warm, shallow waters of the Tethys Sea, which covered much of the region that would eventually become the Himalayas. The fossilized fish species include ancient bony fish, some of which are distant relatives of modern species, providing scientists with valuable insights into the evolution of marine life.
Expeditions also found in the region, the conodonts, small, tooth-like fossils from extinct eel-like creatures. These fossils are significant because they help scientists date the rock formations in which they are found, providing a timeline for the collision of the Indian and Eurasian plates and the rise of the Himalayas.
How Fish Fossils Reached the Himalayas: Plate Tectonics
The presence of marine fossils in the Himalayas is explained by the theory of plate tectonics. Approximately 200 million years ago, during the Mesozoic Era, the Indian subcontinent was part of the southern supercontinent known as Gondwana. North of Gondwana lies a vast ocean known as the Tethys Sea. For millions of years, the Indian plate slowly drifted northward toward the Eurasian plate. It moved at a rate of around 15 centimeters per year—a remarkably fast pace for tectonic plates.
Around 40 to 50 million years ago, the Indian plate collided with the Eurasian plate. This led to the closure of the Tethys Sea. The intense collision between these two plates caused the sedimentary layers of the ancient seabed to buckle and uplift, eventually forming the Himalayan mountain range. Over millions of years, this orogeny (mountain-building process) pushed marine sediments, including fossilized fish and other sea life, to altitudes as high as 8,848 meters (29,031 feet), the height of Mount Everest.
The gradual but persistent collision between the Indian and Eurasian plates continues today, causing the Himalayas to rise by approximately 5 millimeters annually. This ongoing tectonic activity ensures that the fossils once buried deep beneath the ocean floor remain preserved high in the mountains, offering a glimpse into Earth’s distant past
The collision between the Indian and Eurasian plates that led to the formation of the Himalayas was not a single event but a process that occurred over tens of millions of years. The Indian plate initially began its journey northward around 100 million years ago, following the breakup of Gondwana. By the time it collided with the Eurasian plate 40 to 50 million years ago, the Tethys Sea had already begun to shrink.
Scientific Importance of the Fossils
The marine fossils found in the Himalayas are invaluable to scientists studying Earth’s geological history. These fossils provide evidence of the Tethys Sea, which existed for hundreds of millions of years before being closed by the collision of tectonic plates. By studying these fossils, scientists can better understand the types of organisms that lived in ancient oceans and the environmental conditions that prevailed during that time.
Furthermore, the fossils offer critical evidence for the theory of plate tectonics, one of the most important scientific concepts in geology. The movement of tectonic plates not only explains the formation of mountain ranges like the Himalayas but also helps scientists understand the broader processes that govern Earth’s surface, including continental drift and sea-floor spreading.
As Dr. David Rowley, a geophysicist from the University of Chicago, explains, “The fossils found in the Himalayas are a window into Earth’s past. They tell us about the movement of continents, the rise of mountains, and the ancient seas that once covered much of our planet. These discoveries help us piece together the story of Earth’s dynamic history”

Conclusion
The discovery of fish fossils and other marine organisms in the Himalayas is a testament to the dynamic forces that have shaped our planet. From the movement of tectonic plates to the formation of towering mountain ranges, these fossils offer a glimpse into a world that existed millions of years ago. While some may interpret these findings through a religious lens, the scientific explanation rooted in plate tectonics remains the most widely accepted and evidence-supported theory.
