Earlier than the well-known big megalodon, one other fearsome marine predator roamed the oceans. In accordance with a paper printed earlier this 12 months, communication biology, Large shark bigger than trendy nice white sharks Wandered off the coast of present-day Australia 15 million years earlier than megalodon appeared.
Paleontologists analyzed a set of 5 vertebrae discovered on the Australian coast and estimated that this historic shark was in all probability round 8 meters lengthy. For comparability, nice white sharks right this moment are inclined to develop to round 6 meters.
“The entire world would have seemed like a contemporary big shark, as a result of that is the great thing about sharks,” mentioned Benjamin Kjaer, senior curator on the Swedish Museum of Pure Historical past and co-author of the examine.

to the shark 450 million years long Trying again at Earth’s historical past, the ancestors of recent nice white sharks do not seem within the fossil document till 135 million years in the past. And importantly, these ancestors had been small fish, sometimes solely a couple of meter lengthy. Older discoveries advised that really gigantic sharks just like the megalodon (which might attain lengths of 17 meters) developed about 100 million years in the past. However new evaluation suggests big sharks appeared on the scene sooner than beforehand thought.
The staff behind this discovery now plans to seek for fossils of different historic big sharks so as to add shade to the shark evolutionary tree.
