Several fossilized teeth belonging to the extinct megalodon shark have been discovered on the ocean floor in the South Pacific, offering new insights into the ancient marine environment. The findings were made by researchers using remotely operated vehicles (ROVs) in the southwestern part of the Cook Islands.
The teeth, some measuring up to five inches in length, have been identified as belonging to the megalodon, a shark species that roamed the oceans approximately 3.6 million years ago. This prehistoric predator was the largest shark to have ever lived, estimated to be about three times the length of a modern great white shark and weighing around 50 tons. Its powerful jaws and massive teeth were capable of preying on large whales.
Researchers noted that fossilized fish teeth are effective in absorbing rare Earth elements from the surrounding water. Analyzing the concentration of these elements within the megalodon teeth can serve as a valuable tool for tracking past ocean circulation patterns. Additionally, fish teeth often act as a nucleus for the formation of polymetallic nodules, with minerals like manganese and iron accumulating around them over millions of years.
While the megalodon has been extinct for millions of years, its fossilized teeth continue to offer significant clues about the prehistoric ocean environment and the ecosystems that existed at that time.
