Rock artwork positioned in present-day South Africa is perhaps the important thing to discovering an extinct animal species from greater than 200 million years in the past, in line with a current examine revealed in Plos One journal. The animal in query would have gone extinct lengthy earlier than people got here on the scene.
The Horned Serpent Panel, a piece of rock wall on the South African website La Belle France, options the animal in artworks painted by the San folks between 1821 and 1835. The work, which present animals and different frequent parts related to the San, seem alongside the wall below a sandstone overhang. An animal with a protracted physique and down-turned tusks is amongst these portrayed, but it surely doesn’t match any of the identified species that lived within the space throughout that point.

Researcher Julien Benoit of the College of the Witwatersrand in Johannesburg, South Africa has proposed that the portray represents a dicynodont—the fossils of that are ample among the many close by Karoo Basin, a geologic area throughout two-thirds of the nation together with the La Belle France website.
Dicynodonts have been herbivorous animals characterised by turtle-like beaks and walrus-like tusks. The big mammal-like reptile supposedly as soon as roamed South Africa freely between 265 to 200 million years in the past, rising forward of the dinosaurs. They’re a part of the therapsids, which later advanced into mammals within the Mesozoic Period (roughly 252-66 million years in the past).
The San are identified for depicting animals, fossils, and surroundings into their artwork. These fossils recognized across the website have dated way back to 250 million years.
“In lots of instances, their skulls are naturally uncovered by erosion in spectacular methods, making them simple to search out and acquire, and their tusks are so conspicuous that their anatomy isn’t tough to interpret, even to the untrained eyes,” Benoit noticed within the examine.
“Archaeological proof straight helps that the San did discover and transport fossils over lengthy distances, and will interpret them in surprisingly correct methods. If the San might establish the fossilized skulls of dicynodonts as belonging to as soon as alive animals, it’s attainable that their tusked faces might have contributed to their rock artwork.”
In line with Benoit’s analysis, the portray and the fossils look like a match for each other. Different interpretations, nonetheless, aren’t out of the realm of chance.
“Pure creativeness could also be safely dominated out because the San didn’t paint issues that have been utterly imaginary. Their artwork was based mostly on real-life parts, principally animals. A walrus is excluded as a result of no walrus has ever lived in sub-Saharan Africa. A saber-toothed cat is excluded too as their fossils are too uncommon and never discovered within the space. Different tusked animals merely don’t match,” Benoit advised Newsweek.
If the portray in reality depicts a dicynodont, it could then predate the primary formal scientific document of those animals by at the least 10 years.
This discovery might make clear different mysterious depictions which have but to be solved.
