Sharks, the apex predators of the ocean, have a history far more ancient than we might imagine. Fossil evidence reveals that sharks existed as far back as 450 million years ago. This remarkable timeline places their emergence a staggering 90 million years before the first trees appeared on Earth.
The emergence of trees, a pivotal moment in our planet’s history, occurred around 390 million years ago. This means that sharks were already patrolling the primordial oceans while the land was still devoid of the towering forests we know today.
The incredible longevity of sharks is a testament to their evolutionary success. They have endured five mass extinction events, including the devastating Permian-Triassic extinction that wiped out 96% of marine life. Their ability to adapt and survive across such vast stretches of time highlights their resilience and adaptability as a species.
To put their age into perspective, sharks predate even the dinosaurs. Dinosaurs first appeared around 190 million years ago, making them relative newcomers compared to the ancient lineage of sharks. This fact underscores the incredible timespan that sharks have navigated, witnessing the rise and fall of countless species while continuing to thrive in the oceans.
Sharks’ ancient origins are further emphasised by their skeletal structure. Unlike most bony fish, sharks possess skeletons made primarily of cartilage. This characteristic is considered a primitive trait, linking them to the early evolutionary stages of fish.
The film “Older than Trees” draws attention to the remarkable story of sharks. The film’s title itself serves as a powerful reminder of their ancient lineage. Director Pippa Ehrlich uses the film to advocate for shark conservation and highlight the importance of scientific research in understanding and protecting these magnificent creatures.
