Australians discover evidence of 25-million-year-old mega shark

This is an extremely rare find; only three similar fossils have been found in the world.

In 2015, Philip Mullaly was walking on the beach near Victoria, Australia, in a hotbed of fossil finds known as Jan Juc, when he came across what looked like a serrated blade stuck into a boulder. 


After prying it out with his car keys, he realized what he had; a shark’s tooth, about the size of his palm.

“I was walking along the beach looking for fossils, turned and saw this shining glint in a boulder and saw a quarter of the tooth exposed. I was immediately excited, it was just perfect and I knew it was an important find that needed to be shared with people,” recounts Mr. Mullaly.

Museums Victoria was his next call; it eventually sent out a team to excavate the area, and several more 3-inch (9cm) teeth showed up right in the same spot, indicating the shark had died right there, 25 million years ago.

The museum has released its study of the finds this week, and it has confirmed that these are from a great jagged narrow-toothed shark, or Carcharocles angustidens, a 30-foot shark that patrolled the waters off of Australia 25 million years ago.

“Angustidens was a bloody big shark, we’re talking more than 30 feet long,” said Dr. Erich Fitzgerald, Senior Curator of Vertebrate Palaeontology at the Museums Victoria in Melbourne, Australia.

In all, 40 teeth were found there, several of them from the species of shark known as the sixgill shark, or Hexanchus. What likely happened is that as the narrow-toothed shark died in the waters off of Jan Juc, the sixgill sharks descended upon the remains and had a feast, leaving some teeth behind.

A schoolteacher and self-professed fossil hunter, Mullally has collected over 100 fossils, but never anything as old or significant as these.

"If you think about how long we've been looking for fossils around the world as a civilization—which is maybe 200 years—in (that time) we have found just three (sets of) fossils of this kind on the entire planet, and this most recent find from Australia is one of those three," Fitzgerald told CNN.

The teeth will be on display at the museum until October.

Why I wear my life on my skin

For Damien Echols, tattoos are part of his existential armor.

Videos
  • In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
  • This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
  • Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
