Teeth from ancient mega-shark discovered on Australian beach

Meanwhile, the sixgill shark teeth uncovered along with the Carcharocles angustidens fossils appear to belong to several individuals, which probably scavenged on the dead mega-shark and lost their teeth in the process.

The ancient shark was believed to grow up to about 9 meters (30 feet) long, double the size of a great white shark.

So he led a team of palaeontologists, volunteers, and Mullaly on two expeditions earlier this year to excavate the site, collecting more than 40 teeth in total. "I was immediately excited, it was just flawless and I knew it was an important find that needed to be shared with people", Mullaly told the museum.

The teeth, which are nearly three inches in length, belong to the Great Jagged Narrow-Toothed Shark, an extinct mega-shark species that stalked the Australian seas some 25 million years ago and subsisted on a diet of whales, the public museum organization said.

A teacher and fossil enthusiast found a giant set of prehistoric shark teeth estimated to be about 25 million years old at a beach in Australia.

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. 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.

Museums Victoria, and Erich Fitzgerald, senior curator of vertebrate palaeontology confirmed the seven centimetre-long teeth were from an extinct species of predator known as Carcharocles angustidens.

Among the treasure trove of megashark teeth, the team also found prehistoric teeth belonging to a sixgill shark, which is a bottom-feeding scavenger that still swims off the coasts of Australia today.

It's rare to find more than one matching shark tooth at a time because sharks naturally lose their teeth one at a time throughout their lives, so finding such a large number in the same place was unexpected. The theory is that the other sharks came to feast on the carcass of the dead mega shark and lost teeth during the feast. "They are still sharp, even 25 million years later".
