The recent action blockbuster "Megalodon" has set off a discussion about the prehistoric mega-shark, the related species of large hard enamel tooth fossils can be preserved to this day, Australian fossil archaeologist Philip Mullaly once walked on the beach in Victoria, South Australia, fortunately found a prehistoric narrow-toothed human shark (Carcharodon angustidens) tooth fossils, and then found a complete set of prehistoric shark tooth fossils, It is also the first complete set of narrow-toothed human-eating shark fossils found in Australia.
The fossil teeth of the narrow-toothed human-eating shark are similar to those of the great white shark, but are more than twice the size of the 7 cm teeth of the ordinary great white shark, and after more detailed investigation, a complete set of shark tooth fossils was found at the site. A deeper investigation found that this set of tooth fossils belonged to the Carcharodon angustidens, translated as the Angsti shark, and was an extinct anophotomorphic shark fish that lived in the waters of New Zealand and Australia (25 million years ago) from the Oligocene to the Miocene.
It is estimated that the narrow-toothed human-eating shark is also more than twice the length of the great white shark, approaching 18 meters. Scholars believe that the narrow-toothed man-eating shark uses whales as food.
Dr Erich Fitzgerald, Senior Director of Vertebrate Paleontology at the Victoria Museum, said: "These valuable excavated fossils are one of only three sets of intact teeth of the narrow-toothed human shark in the world, and the first one to be unearthed in Australia. "This set of precious fossils is currently in the collection of the Victoria Museum and is currently on display at the Melbourne Museum under the name of the National Science Week event.
