The largest dinosaur foot discovered by US authorities

About 150 million years ago, a long-necked giant trampled in the state of Wyoming in the American Midwest and left behind what the researchers said . The biggest dinosaur foot ever discovered.

The bones of the foot, found under a series of tail bones, extend about one meter wide and are believed to belong to a brachiosaurus, a group of bones. extinct herbivores called sauropods, says the results in PeerJ review

This is an "exceptionally large foot, larger than the elements of all other sauropod bones known," said lead author Anthony Maltese, of the Rocky Mountain Dinosaur Resource Center in Woodland Park, Colorado. AFP in an email.

"I am often asked what is the largest / longest dinosaur / whatever has ever existed, and in this case I can provide an answer now," he said. the immense size of the creature, its thigh bone That said, the brachiosaurus of Wyoming is not the largest dinosaur known to man, since other digs have found fossils of 39 animals that were probably bigger, but that is the largest foot in evidence "There are traces and other incomplete skeletons of Australia and Argentina that seem to come from Even larger animals, but these gigantic skeletons were found without the feet, "said co-author Emanuel Tschopp, a postdoctoral researcher at the American Museum.

"This beast was clearly one of the largest that has ever walked in North America."

The discovery also extends the known northern range of brachiosaurs, showing that they have traveled a vast Utah region in Wyoming, added the Maltese.

"Brachiosaurs are quite rare with regard to dinosaurs, and being able to extend their geographical range of several hundred kilometers is exciting and could help us understand them."

Maltese and his colleagues at the University of Kansas fell on their feet, nicknamed "Bigfoot," in 1998, while he was an undergraduate student.

Then, Life and Work

"It has become very difficult to find time to follow the literature in order to complete the project," he told AFP

"Fortunately, by procrastination, it has allowed me to find a better place to go. bademble an absolute killer. International research team and have the ability to 3D scan all the bones for the best data of any big dinosaur foot so far. "
