Sharks are Older Than Trees and The Rings of Saturn
Sharks are one of the oldest species that still exist to this day. The earliest shark fossil dates back as far as 400 million years ago. This is so long ago, there are a few examples to put into perspective just how crazy that is. The first known tree dates to just 385 million years ago. On top of that, the rings of Saturn were only formed roughly 100 million years ago.
To make things even more crazy, sharks almost went extinct roughly 20 million years ago when the shark population randomly dropped by 90%. The Earth lost 70% of its shark species that once existed. If a full extinction event happened, sharks would have been listed among the dinosaurs as a crazy creature that we can’t imagine living among humans.
