Outside Fort Worth, scientists unearthed the remains of enormous creature not commonly associated with the North Texas plains: a mega shark. Scientists from the University of Oklahoma announced the discovery Wednesday in the clinical journal Plos One with an article entitled “A Gigantic Shark from the Lower Cretaceous Duck Creek Development of Texas.”. “
These specimens are vital since they represent a few of the biggest released lamniform shark vertebrae from the Early Cretaceous of The United States and Canada.”.
Lamniform is a typical family of sharks that consists of the Great White– however this sharks appears practically twice as big as the kin of Jaws. It was recognized based upon 3 fossilized vertebrae, which give scientists a great estimate of the shark’s length– they say about 20 feet long at minimum.
But the exact species of the shark is unclear. Researchers believe it’s leptostyrax macrorhiza, of which bigger specimens have been unearthed in Kansas. The shark lived about 140 million years earlier, when nearly all of Texas was covered in a shallow sea or muddy swamps and the air was warmer than it is today.
Tiny shelled sea creatures and terrific aquatic predators milled about the vast waters of the Lone Star State. It was a time of greenhouse environment, when high international temperature levels melted most polar ice. At the same time, the sluggish birth of the Rocky Mountains in The United States and Canada pressed down the earth throughout much of the continent.
Add those together and you have oceans in Texas. However the Texas shark rattles researchers’ concepts of those very ancient seas, where giant lizard-like animals were formerly believed the dominant and sole predator of the seas. Now they know there were at least 2 mammoth beasts that swam through Texas in those days.
The discovery also enhances the idea that sharks, especially lamniform sharks, are some of the most ancient huge animals of modern-day times.
