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.
One man found a pair of fossilized teeth from the great jagged-narrow toothed shark on a beach south of Melbourne.
Paleontologist-a lover Philip Mullaly came across a unique artifact when walking through the countryside, Jan-JUC, located about 100 kilometers from Melbourne.
Fitzgerald said he was first contacted by Mullaly past year about a different discovery, during which he briefly mentioned the find at Jan Juc, but it wasn't until the amateur fossil hunter brought the teeth into the museum that Fitzgerald realized how significant the discovery was. "I knew it was an important find, which you want to share with people".
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.
The recently found fossilized mega-shark teeth were dated 25-million-year-old and are now on display at the Melbourne Museum until October 7th. The teeth are the first of their kind found in Australia and one of only three discoveries in the world.
While most of the fossilized remains belong to Carcharocles angustidens and seem to have come from a single individual, the paleontologists also uncovered several smaller teeth left behind by sixgill sharks (Hexanchus), which still wander the oceans today.
Fitzgerald said he believes there may be even more shark teeth at Jan Juc and even parts of a spinal column lodged in the cliff, based on what he saw during the excavation.
So the best news is that the Carcharocles angustidens is not going to kill us, or Jason Statham.
In the video below, Fitzgerald comments on the importance of this discovery and the contribution that citizen scientists like Mullaly bring to paleontology.
The teeth belonged to Carcharocles angustidens, an extinct species that's closely related to the famous giant C. megalodon.
