World's Largest Dinosaur Foot Found

Fossilized dinosaur foot almost one meter wide, dug 20 years ago northeastern Wyoming, is the largest found to date, according to an international team of researchers in the journal PeerJ.

The rest of the dinosaur’s skeleton has yet to be identified, but the size and shape of the foot bones indicate that it once
belonged to a brachiosaurus . These long-necked herbivores lived about 150 million years ago, during the late Jurassic Period.

“These things were just huge,” says study co-author David Burnham, a paleontologist at the University of Kansas Biodiversity Institute and the Natural History Museum in Lawrence. Burnham estimates that the new dinosaur, nicknamed Bigfoot, may have been about 100 feet long, about the length of a blue whale.

During the Upper Jurassic, brachiosaurs inhabited parts of North America in what is now Colorado, Utah, and southern Wyoming. These excavations indicate that brachiosaurs roamed further than previously thought.

Paleontologists used 3D scanning and detailed measurements to compare the specimen to the feet of numerous dinosaur species, allowing them to confirm for the first time that the fossil is the largest ever found.

“There are footprints and other incomplete skeletons from Australia and Argentina that appear to be of even larger animals, but those gigantic skeletons were found without the legs,” said study co-author Emanuel Tschopp of the American Museum of History’s Paleontology Division. Natural. “This beast was clearly one of the largest to ever walk in North America.”

As it is, we now have the fossil of one of the largest creatures that ever walked on Earth 150 million years ago (originally discovered in Wyoming in 1998).

The 1998 excavation was carried out by an expedition team, including Anthony Maltese, lead author of the new study. Recalling the excavation 20 years ago, he said: “It was immediately apparent that the foot, almost a meter wide, was from an extremely large animal, which is why the specimen was nicknamed Bigfoot.”

The rocky area in which the fossil was discovered, the Black Hills region of Wyoming, is famous for being the home of Mount Rushmore (a national monument featuring the faces of US Presidents George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln) and likely contains more well-preserved dinosaur skeletons, so the team of paleontologists continues to study fossils in the region.

The main problem to carry out medical research is to have willing volunteers for it. And if they come out for free, much better. This is the story of unethical behavior in medical research.
