Prehistoric shark with 'spaceship-shaped teeth', discovered alongside the most famous Tyrannosaurus



The remains of a small prehistoric shark, which lived 67 million years ago in the age of dinosaurs, were found to the surprise of scientists and spectators alike, according to a new study.

In what was found, fossilized shark teeth were discovered today's present-day South Dakota and was found in the same deposits as Sue the Tyrannosaurus rex, perhaps the famous T. rex fossil ever excavated. The freshwater shark had odd triangular teeth and was referred to as Galagadon Nordquistae due to its resemblance to the spaceships of the 1

980s "Galaga" video game.

"It was so small you might miss it if you're not looking closely," retired chemist Karen Nordquist, a volunteer who discovered the fossils, said in a press release. "To the naked eye it just looks like a little hump, you have to have a microscope to get a good overview."

Described by Terry Gates, the lead author of the study, as the "diameter of a pinhead" and "size of a grain of sand," the teeth were only one millimeter wide and fell with the small stature of the sharks with less than two feet in length.

"It's not exactly Jaws," said Pete Makovicky, the dinosaur curator of the Field Museum and one of the co-authors of the study in the publication.

Makovicky likened it to modern bamboo sharks "He probably had a flat face and was probably camouflaged, as his relatives today have a camouflage pattern."

Contrary to the conception of young children and B-movie screenwriters, the shark did not look to eat T. rex or any other dinosaur.

"Galagadon did not fall prey to T. Rex, Triceratops or other dinosaurs that have fallen into the rivers," Gates said in a statement. "This shark had teeth for fishing small fish or crushing snails and Crawdad's. "

" This was not a Sharknado event – these animals came from the sea on rivers, "Makovicky said in the release Concerning the popular television films made for SyFy, which have become a cultural phenomenon.

The topography of South Dakota today is completely different from 67 million years ago, Gates added, "It may seem strange today, but about 67 million years ago today's South Dakota was covered with forests, swamps, and meandering rivers. "

Gates said the discovery of Galagadon will help researchers learn the Cretaceous against the extinction of non-avian dinosaurs. [19659006] WORLD'S GREATEST BIG WHITE COCK & # 39; DEEP BLUE & # 39; DIVES DIVER A CLOSE-UP: "DAMENCE THAT HE WAS MY HEART, EXPLODE & # 39; (19459019)]

"Any species in an ecosystem plays a supporting role and keeps the entire network together," he said. There is no way for you to understand what has changed in the ecosystem during the mass extinction of the Cretaceous, without knowing all the wonderful species that existed before.

The study detailing the results was published in the Journal of Paleontology .
