Sphinx may have been built from a natural rock feature eroded by wind, study claims

We see an orange sphinx-like mound with orange "erosion" lines going around it. .

The ancient Egyptians may have crafted the Sphinx, a 4,500-year-old monument at Giza that stands in front of the pyramid of Khafre not completely from scratch but rather on a natural feature that already looked surprisingly sphinx-like, a new study suggests.

In an Oct. 17 study published in the journal Physical Review Fluids, a team from New York University suggested that a yardang, a windblown ridge of rock sticking out of the ground, can naturally develop into a sphinx-like formation.
