We have the evidence to prove that this mammoth shark did exist sometime on the earth.
Scientists found the head of a 330-million-year-old shark in a Kentucky cave. The remains of the ancient animal were found in Mammoth Cave National Park.
The shark fossil, which was discovered by scientists who were investigating the cave system, is thought to be up to about 330 million years old, according to John-Paul Hodnett, a paleontologist and program coordinator at Dinosaur Park in Maryland.
The scientists sent Hodnett photos of the findings so he could help identify them. He was able to identify most of the fossils, but what got him "really excited" was to see a number of shark teeth associated with large sections of fossilized cartilage.
Shark skeletons are made of cartilage, which does not fossilize as well as bone — so it is rarely preserved. Preserved cartilage can only be found in a few select locations around the world.
Shark teeth, on the other hand, are among the most common fossils found around the planet since they are replaced throughout the animal's life.
