The shark was among the top predators during its heyday 25 million years ago, feasting mostly on small whales.
The shark was about twice the length of a normal great white shark.
According to reports, an amateur fossil enthusiast named Philip Mullaly recently found teeth that belonged to a Carcharocles angustidens, a shark that lived between 33 to 22 million years ago, and was twice the size of a modern great white. A cousin of the famous megalodon, this very big shark would have measured over 30 feet in length - aka, twice the length of a great white shark.More news: USA stocks closed mixed amid data, earnings
The teeth went on public display Thursday and will remain available to public view until October. The next time you're on a beach, pay closer attention to the rocks - maybe you'll get lucky and find a prehistoric fossil of your own.
Secondly, these rare fossils are among a handful of ancient shark teeth to have been found as a set. Fitzgerald said that each Carcharocles angustidens tooth they found came from a different spot in the shark's jaw, which meant that all of the teeth most likely came from the same individual megashark. This is because sharks can lose even one tooth a day and their skeletons are made of cartilage, which is hard to fossilize.
Researchers believe those teeth were left behind as a result of getting lodged in the carcass of the Great Jagged Narrow-Toothed Shark as smaller sharks fed on it after the much larger animal died.More news: NASA blasts off historic probe to 'touch Sun'
He explained that nearly all fossils of sharks worldwide were just single teeth, and it was extremely rare to find multiple associated teeth from the same shark.
Fitzgerald's team has finished their field research and are now working to learn more about how the teeth of the Great Jagged Narrow-Toothed shark developed in order to better understand its evolutionary history.
The teeth belonged to Carcharocles angustidens, an extinct species that's closely related to the famous giant C. megalodon. "The stench of blood and decaying flesh would have drawn scavengers from far around", Museums Victoria palaeontologist Tim Ziegler said in a statement. For now, those potential samples are about 20 meters (65 feet) high, out of the reach of excavators.More news: State of emergency declared in Charlottesville for ‘Unite the Right’ anniversary
