Imagine finding the remains of a creature so massive it makes your jaw drop! That's exactly what happened on a beach in Australia, and it's a discovery that's got experts buzzing.
A Mega-Shark Mystery Unveiled
On a stretch of coastline near Darwin, a city in northern Australia, an incredible find was made. Five ancient vertebrae, dating back a whopping 115 million years, belonged to a lamniform shark, a distant relative of the great white and mako sharks we know today.
But here's where it gets controversial... these vertebrae were not just old, they were huge! In fact, they were over 12cm in diameter, significantly larger than the 8cm vertebrae of modern great whites.
Based on the size of these bones, experts estimate this shark was a monster, measuring between 6 and 8 meters in length and weighing over 3 tonnes!
And this is the part most people miss... the researchers believe these fossils belonged to an extinct family of sharks called Cardabiodontidae, giants that roamed the oceans over 100 million years ago. But the real surprise? This Darwin specimen is 15 million years older than any other known Cardabiodontid, suggesting that sharks were experimenting with massive sizes much earlier than we thought.
The study, led by the Swedish Museum of National History, has been published in Communications Biology, and it's a game-changer for our understanding of ancient marine life.
