Teeth from ancient mega-shark discovered on Australian beach

Fossilized teeth from an ancient mega-shark, considered a close cousin to the megalodon, have been discovered on an Australian beach and are set to be unveiled Thursday, Museums Victoria announced.

Most of the teeth belonged to Carcharocles angustidens, but in addition, they found something even more surprising - several teeth of a smaller shark, the sixgill shark (genus Hexanchus).

A fossil hunter has made the discovery of a lifetime on a beach in Australia.

He told Museums Victoria, and Erich Fitzgerald, senior curator of vertebrate palaeontology, confirmed the seven centimetre-long (2.7 inch) teeth were from an extinct species of predator known as the great jagged narrow-toothed shark (Carcharocles angustidens).

According to the scientists, this discovery is significant, as this set of teeth belonging to Carcharocles angustidens is the third known worldwide and the first found in Australia.

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.

The New York Times reports Mullaly found the teeth in 2015. They'll be on display until October 7.

Mullaly donated the teeth to Museums Victoria in Australia to keep as part of their collection.

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.

Paleontologist-a lover Philip Mullaly came across a unique artifact when walking through the countryside, Jan-JUC, located about 100 kilometers from Melbourne. She could grow by more than nine metres in length. That cartilage does not easily decompose, which is why individual shark tooth fossils are somewhat common.

Fitzgerald also determined that all of the teeth most likely came from the same individual shark. However, Fitzgerald said that finding multiple teeth from a single shark is extremely rare.

"This find suggests they have performed that lifestyle here for tens of millions of years", Museums Victoria paleontologist Tim Ziegler said.
