Man finds 25-million-year-old shark teeth

After his initial find, Mullaly worked with a team from the Museums Victoria, the organization that administrates the Melbourne Museum, to uncover nearly 40 teeth in total between December 2017 and January 2018.

Fossil enthusiast Philip Mullaly holds a giant shark tooth-evidence that a shark almost twice the size of a great white once stalked Australia's ancient oceans-at the Melbourne Museum on August 9, 2018.

Secondly, these rare fossils are among a handful of ancient shark teeth to have been found as a set.

In 2015 Philip Mullaly was strolling along a beach in Victoria, Australia, when he spotted what looked like a shining serrated blade stuck in a boulder.

The about 3-inch teeth belonged to one of the most significant predators that ever lived in the world's oceans, the Great Jagged Narrow-Toothed shark. "I was immediately excited, it was just flawless, and I knew it was an important find that needed to be shared with people", explained Phillip Mullaly.

Colloquially known as the great jagged narrow-toothed shark, this predatory mammoth prowled the ancient seas 25 million years ago, during the Oligocene epoch, preying on penguins and small whales.

"These teeth are of global significance, as they represent one of just three associated groupings of Carcharocles angustidens teeth in the world, and the very first set to ever be discovered in Australia", Fitzgerald said.

"By donating his discovery to Museums Victoria, Phil has ensured that these unique fossils are available for scientific research and education both now and for generations to come". Although the team found evidence that there was only one megashark there, they found indications that there were several different sixgill sharks on the scene. She could grow by more than nine metres in length. As scientists say, the sixgill's teeth were from several sharks, which most likely were feeding on Carcharocles angustidens' carcass.

So with a team of paleontologists, Fitzgerald and Mullaly returned to the beach previous year, which was south of Melbourne.

The teeth belonged to Carcharocles angustidens, an extinct species that's closely related to the famous giant C. megalodon. "They are still sharp, even 25 million years later".
