draw conclusions about how some dinosaurs grew. "What our (study) would do is tell you that much of the head base, the neck and the paws, much of that is possible to carve by nature, by erosion. Contrary to what many people think, not all dinosaurs lived during the same geological period. The question is how much was naturally existing and then further modified," Ristroph told CNN. … No one says this is an entirely human carved thing and no one says it's entirely nature carved. The New York University researchers said their results suggest that Sphinx-like structures can form under fairly commonplace conditions, but their findings don't resolve the mysteries behind yardangs and the Great Sphinx. … Our experiments could add to the understanding of how these yardangs form," he said. "Some of them look so much like a seated lion, or a seated cat, that they're sometimes called Mud Lions. The additional power is also much appreciated. Within the desert, there are yardangs that exist that naturally look like seated or lying animals with raised heads, Ristroph told CNN. dinosaur, or mythical creature), she is unstoppable Can you overcome the. The team behind the study, which the release said had been accepted for publication in the journal Physical Review Fluids, created clay-model yardangs - a natural landform of compact sand that occurs from the wind in exposed desert regions - and washed the formations with a fast stream of water to represent the wind.īased on the composition of the Great Sphinx, the team used harder, non-erodible inclusions within the featureless soft-clay mound, and with the flow from the water tunnel, the researchers found a lion form had begun to take shape. "Our laboratory experiments showed that surprisingly Sphinx-like shapes can, in fact, come from materials being eroded by fast flows."

"Our findings offer a possible 'origin story' for how Sphinx-like formations can come about from erosion," said senior study author Leif Ristroph, an associate professor at New York University's Courant Institute of Mathematical Sciences, in a news release. Weve shipped millions of items worldwide for our 1+ million artists. Now, a new study offers evidence to suggest that theory might be plausible, according to a news release from New York University.Ī team of scientists in NYU's Applied Mathematics Laboratory set out to address the theory by replicating the conditions of the landscape about 4500 years ago - when the limestone statue was likely built - and conduct tests to see how wind manipulated rock formations. If its a dragon, maybe you want to start with a long, sinuous shape for the body. More than 40 years ago, Farouk El-Baz - a space scientist and geologist known for his field investigations in deserts around the world - theorised that the wind played a big hand in shaping the Great Sphinx of Giza before the ancient Egyptians added surface details to the landmark sculpture.
