Did you know that sharks have been swimming in Earth oceans longer than trees have existed on land? Fossil evidence reveals that the earliest shark scales date back approximately 450 million years ago, during the Late Ordovician Period. In contrast, the earliest known tree species, known as Archaeopteris and Wattieza, did not appear on Earth until roughly 385 million years ago during the Middle Devonian Period.

This means sharks roamed the ancient seas for tens of millions of years before a single forest ever cast a shadow on soil. They survived four major mass extinction events, including the devastating Permian Triassic extinction that wiped out most life on the planet.

Over hundreds of millions of years, shark bodies adapted to survive drastic climate shifts, asteroid impacts, and shifting ocean currents. Today, modern sharks still carry ancient evolutionary blueprints that outlasted the dinosaurs and countless prehistoric ecosystems.
