The giant extinct shark Megalodon dominated the ocean millions of years ago, but even this terrifying marine carnivore was unaffected by tooth problems.
Recent analysis of Megalodon ((((Otodus Megalodon) Rare abnormal teeth (grooves to the middle) suggest that tooth malformations can trace their roots to damage to the giant shark’s jaw, probably due to the counterattacked prey. .. In a diagram showing a possible encounter, a fish pierces the jaws of a predator chasing with its sharp beak. This may have set the stage for Megalodon to grow cracked teeth.
Another possibility is that a large shark was pressed by the spine from a stingray, scientists wrote in a new study.
In humans and other mammals, genetic factors, illnesses, or injuries can affect tooth buds and cause tooth abnormalities known as “double tooth pathology.” Such teeth can represent two tooth buds that combine to form one tooth, a process called fusion, or one split tooth bud (called a gemination). However, little is known about this pathology of sharks.
For research, researchers analyzed split megalodon teeth 4 inches (10 centimeters) long, along with split fossil teeth from other sharks, which may have caused deformation. I have identified something. Scientists have concluded that trauma is most likely the cause of prehistoric torn teeth. Encounters with damaged teeth on Megalodon may have affected shark hunting and feeding.

Megalodon is one of the largest predators ever to live, at least 50 feet (15 meters) long. 65 feet (20 m) long According to some estimates, Live Science previously reported.To see it, the present age Great white shark ((((Great white shark) Usually, the length is 20 feet (6 m) or less.
Even though it’s a Megalodon thriller. “Meg“(Warner Bros Pictures, 2018) suggested that lonely Megalodon may still be lurking in the depths of the ocean. Most Megalodon fossils date back about 15 million years to giant sharks. All evidence disappeared from the fossil record at about 2.6 after extinction, a million years ago.
Most of the fossils of Megalodon that have survived to date are teeth because the shark’s skeleton is made of cartilage, is not as strong as bone, and is usually not fossilized. Like modern sharks, Megalodon was constantly losing teeth and growing new ones. And a constantly regenerating supply was stored in its jaw. Thanks to this so-called tooth conveyor belt, some sharks can lose and replace tens of thousands of teeth over their lifetime. Raleigh emailed Live Science.
“It’s like we lose 20 baby teeth every month,” Abrahami said.

To find out what might be at the root of the split Megalodon teeth, researchers examined hundreds of shark fossil teeth in the collection of the North Carolina Museum of Natural Sciences in Raleigh. They found only two more examples of abnormal split tooth deformation. Two teeth of the bull shark. Carcharhinus leucas, It was a species that lived with Megalodon millions of years ago (but much smaller, reaching a maximum length of about 12 feet (3.7 m)) and still exists today.
They measured deformed teeth along with normal teeth from two shark species and then calculated X-ray Tomography, or CT scanMap the pulp cavity of the bull shark tooth and the vascular network inside the megalodon tooth to see how they developed.
Their analysis shows that germination produces double teeth rather than fusion, based on where the pulp cavities and networks divide the “and lack of major root abnormalities” in all double teeth. Suggested that it is likely. Scientists have reported that split teeth are also very symmetric, not when formed from the fusion of two tooth buds at different stages of development.
The root of the problem
Abrahami explained that puncture wounds are more likely to cause traumatic damage to tooth buds than sharks usually shrug or infectious diseases. “Sharks are strange in that they appear to be particularly resistant to getting sick from infections,” he said. So, “it’s believed that other tooth malformations in sharks are most likely due to trauma,” he added. Modern bull sharks are known to feed on pointed prey that can cause injuries such as sawfish, rays and sea urchins. Megalodon is thought to have preyed primarily on marine mammals, perhaps fish and turtles, but its diet may have been more diverse, including more than expected marine organisms with pointed defensive weapons. ..
With about 300 teeth in his mouth, Megalodon probably wasn’t too annoyed by one broken tooth. However, if the tooth bud is injured by a spine or spine caught on a large shark’s jaw, “it could probably cause great pain to the animal and make hunting more difficult,” Abrahami said.
A closer look at Megarodon’s teeth in this study not only provides new insights into shark tooth malformations. It also raises questions about how common double tooth conditions were in other animal strains that had continuous tooth replacement, such as: dinosaur (Including toothed birds) And the crocodile, Abrahami, said.
“I’ve seen a lot of hadrosaurus teeth in my life. It’s a dinosaur, with abundant battery conveyor belts for teeth, and none with double teeth. Why ??” Asked. “So I really hope future researchers will explore this more.”
The findings were published in the journal on May 11th. PeerJ (Opens in a new tab)..
