The megalodon wasn’t the only megashark with giant teeth — check out these teeth from the great jagged narrow-toothed shark
The megalodon, a giant shark that went extinct at least 2 million years ago, has recently gotten more attention with the release of the movie "The Meg." But the megalodon wasn't the only giant shark in the prehistoric ocean.

"The Meg" had one of the biggest opening weekends at the box office this year, taking in more than $45 million. At the center of the movie is the megalodon, a giant
Shark skeletons are mostly made of cartilage, which does not fossilize well, so scientists have relied on the shark's 7-inch-long teeth and plate-sized spinal bones to learn more about the animal.
But stunningly large teeth — one of the megalodon's defining features — are not unique to this prehistoric animal. In 2015, amateur fossil hunter Philip Mullaly found 45 shark teeth on a visit to his local beach in Australia. The teeth, most of which belong to a megashark that preyed on small whales about 25 million years ago, are part of a new exhibit that opened August 9th at Museums Victoria in Melbourne, Australia.

“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," Mullaly said in a statement. "I was immediately excited, it was just perfect and I knew it was an important find that needed to be shared with people."
Mullaly donated the teeth to Museums Victoria, adding a rare display to the organization. Collections of this kind tend to include just single teeth.
The teeth suggest Australia's oceans used to be home to a shark almost twice as big as a great white. Some of them are roughly 3 inches long, and scientists have determined they belong to an extinct species called the great jagged narrow-toothed shark, which grew to a length of about 30 feet.
People have previously discovered single teeth belonging to this shark, but Mullaly was the first to find a whole set in Australia.
According to The New York Times, scientists excavated the teeth in late 2017 and early 2018. They discovered several more teeth on their trips; these belonged to the sixgill shark, which is smaller than the great jagged narrow-toothed shark.

Tim Ziegler, a paleontologist at Museums Victoria, said in a statement that the smaller teeth came from multiple sharks and would have come loose while the sixgills were eating the carcass of a dead great jagged narrow-toothed shark.
Sixgill sharks are still alive in Australia today, feeding on the remains of whales and other animals. The 45 shark teeth will be on display at Museums Victoria through October 7.
