Megalodon spent millions of years tightening their massive teeth

The megalodon which is considered one of, if not the largest marine predator ever lived, had huge teeth, some approaching almost 8 inches in length. A new study says that the giant shark spent millions of years and developed its teeth before taking its iconic form. The study, published in the Journal of Vertebrate Paleontology, looks at the differences between 359 fossilized megalodontes found on Calvert Cliffs (Chesapeake Bay, Maryland) and compared them to the massive shark ancestor, Otodus obliquus who had smooth teeth and gaps (mint teeth) on both sides of the main tooth. "This transition was a very long, protracted process, eventually resulting in the perfect cutting tool &#821 1; a broad, flat tooth with uniform serrations," says study leader author Victor Perez in a statement. "It is not yet clear why this process took millions of years and why this feature [the two mini teeth on the sides] was lost."

MEGALODON SHOCKER: A HIGH KILLER HAIR MUST BE EXPRESSED BY GREAT WITCHES

Otodus obliquus which lived between 60 million and 40 million years ago, was estimated to be between 30 and 40 feet long, based on the size of fossil teeth previously found.

It is possible that “the crushers,” working in conjunction with the main tooth, acted as a triangular approach, resembling a fork “to seize and tear moving fish, the statement says.

About 87 percent of the teeth that have been dated Between 20 and 17 million years ago, there were gaps, while only 33 percent of those found from 14.5 million years ago had them, at 7.6 million years there were no fossilized teeth.

Some teeth contained “small shoots or pronounced serrations “where the gaps were once, while others lacked them.

The developed teeth probably made megalodons to a better hunter, with Perez suggesting that it was a” single-strike tactic, “made to immobilize the booty and let it

“It would only diminish after that,” he said. “A shark would not want to grab a choice because it will shatter and possibly damage the shark in the process.”

It is still e unclear what the exact cause of the change in the teeth was, something that Perez said is “still a mystery”. “We wonder if something was tweaked in the genetic pathway for dental development,” he added.

MEGALODON CAN BE FILLED BY AN EXPLODATION STAR

Megalodon extermination

There are several theories of what led to the eradication of the massive megalodon, which is believed to have reached 60 feet long and weighed as much as 120,000 pounds.

A new study suggests that the giant shark may have died earlier than previously thought (3.5 million years ago) and may have been out of its successor – the great white.

Another study suggests that “one or more supernova” about 2.6 million years ago may have caused a lot of extinction of a large number of marine megafauna, including the dreaded megalodone.
