Emily DeMarco, Science, has written a informative article about archaeological chemists efforts to analyze the above collection of petroglyphs through DStretch and x-ray fluorescence to determine
the original shapes made out of red ochre, which date to the late Archaic period
( 2,000 to 4,000 years ago).

"Rock art researchers and archaeologists have disagreed strongly with that interpretation. In the mid-1990s, several scientists with eyes trained to recognize one of the region’s most famous styles of rock art—known as Barrier Canyon style—first argued that the so-called pterosaur was actually five figures: two humanlike ones and three animals, including what looks like a bighorn sheep and a horned serpent. Such pictographs are common in Barrier Canyon style, which is recognizable by the tiny “attendants”—which include people, birds, ungulates, and snakes, among others—nestled among the humanlike and often life-sized figures notable for their large eyes and elongated bodies."
