Australian teacher finds prehistoric shark teeth


He stressed that it is rare to find a few teeth of one shark.

According to the museum, these teeth provide evidence that a shark which would have grown to more than 30-feet in length, almost double the size of a great white, "once stalked Australia's ancient oceans" approximately 25 million years ago.

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 museum said the teeth belonged to an extinct species called the Great Jagged Narrow-Toothed Shark (Carcharocles angustidens), which could grow to twice the size of a great white.

"These teeth are of global significance, as they represent one of just three associated groupings of Carcharocles angustidens teeth in the world", Fitzgerald explained. During two expeditions taking place last December and January, Fitzgerald led a team of experts to the location where Mullaly found the teeth to excavate. The teeth discovered on the beach were around 7 cm (2.75 inches) in length.

He contacted Erich Fitzgerald, a paleontologist at the Museums Victoria in Melbourne, which announced the find on Thursday.

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

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.

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. "The stench of blood and decaying flesh would have drawn scavengers from far around", Museums Victoria palaeontologist Tim Ziegler said in a statement.

"Sixgill sharks still exist off the Victorian coast today, where they live off the remains of whales and other animals". "They are still sharp, even 25 million years later". As scientists say, the sixgill's teeth were from several sharks, which most likely were feeding on Carcharocles angustidens' carcass.
