New species of Dinosaur-era Giant Shark discovered in Kansas by researchers

Scientists have recently discovered a new species of giant shark from disaur era in Kansas. Researchers believe that this new shark is an ancient cousin of sand tiger and great white sharks that we kw today. It is believed that y have discovered fossilised remains of ar disaur-era creature belonging to late Cretaceous period which was roughly 144 million to 66 million years ago.

A new species of shark

new species that has been named Cretodus houghtorum was discovered at a dig site in Kansas.
fossil shark was discovered and excavated in 2010 by researchers Kenshu Shima and Michael Everhart and two central Kansas residents, Fred Smith and Gail Pearson.

name houghtorum is in hour of Keith and Deborah Houghton, landowners who donated specimen to museum for science. While skeleton is largely incomplete, it still represents best Cretodus specimen that has been discovered in rth America. skeleton and remains that were excavated contain 134 teeth, 61 vertebrae, 23 placoid scales and fragments of calcified cartil, which when analyzed by scientists provided a vast amount of biological information about extinct shark.

large body size of shark and anatomical data les researchers to believe that it may have been a sluggish shark and that it belonged to group called Lamniformes. This group includes modern-day sand tiger shark and great white making m distant cousins.

All you need to kw in dental records

Most of what is kwn about shark is deduced from its isolated teeth. Researchers during course of excavation stated that y discovered a specimen of Cretodus crassidens, a species originally found in England. But t even a single tooth matched tooth shape of original Cretodus crassidens specimen or any or kwn species of Cretodus. That is when y realized that y were dealing with a new species altoger. researchers estimate that shark could have reached up to about 22 feet.
