The remains of a small prehistoric shark that lived in the dinosaur era 67 million years ago were found to be a surprise both by scientists and viewers, according to a new study. is now South Dakota and is found in the same fields as Sue, Tyrannosaurus rex, perhaps the famous fossil image of T. rex ever found. The freshwater shark had strange triangular teeth, and due to its similarity to the spacecraft in the Galaga video game in the 1

The topography of South Dakota today is much different than 67 million years ago, Gates added. 67 million years ago, what is now South Dakota has been covered with forests, swamps and rising rivers. "
Gates said Gauldad's discovery would help scientists learn more about the chalk before the disappearance of non-avian dinosaurs. THE BIGGEST FORWARD OF THE WORLD WORLD SHOW THE GLOBAL BLUE RACE LOCKS: "MY HEART MY HEART WATCHES"
"Every species in an ecosystem plays a supportive role in maintaining the whole network." There is no way for w To understand what has changed into the ecosystem during the mass extinction at the end of the chalk, without all the wonderful species that existed previously..
