A 200-year-old South African cave painting made by the region’s first inhabitants, the San people, appears to depict an animal that has been extinct for over 200 million years. A long-bodied animal with downward-turned tusks, the warm-blooded, lizard-like creature called a dicynodont (two-toothed dog) roamed the area before the first dinosaur appeared and died off at the end of the Triassic. If the artwork from the cave’s Horned Serpent panel at La Belle France (Free State Province, South Africa) is of this extinct species, its creation would predate the first known scientific classification of a dicynodont by at least a...

Art imitates life ... maybe.There’s something intriguing, even frightening, about the image of an ancient horned serpent roaming across the land. Thanks to some suggestive fossils and legends of old, talk of such a creature isn’t a new concept. But the recent discovery of 200-year-old rock paintings found in South Africa now has scientists hypothesizing that this ancient creature may have been far more than just a legend. The first formal scientific descriptions of this horned serpent—a supposed member of the dicynodont group—appeared in 1845. Considering the abundance of dicynodont fossils found in the Karoo Basin in South Africa, some...

More than 1500 years ago, a vast culture known as the Hopewell tradition (or Hopewell culture) stretched across what is today the eastern United States. The cause of the culture's decline has long been debated, with war and climate change two of the possibilities, but now a new avenue of inquiry has opened up: debris from a near-Earth comet. Researchers working across 11 different Hopewell archaeological sites covering three states have found unusual concentrations of iridium and platinum in their digging – telltale signs of meteorite fragments. Meanwhile, a charcoal layer in the sediment suggests an intense period of high...

Researchers from the University of Cincinnati have found evidence of a cosmic cataclysm 1,500 years that may be responsible for the downfall of the Hopewell Culture. The Hopewell Culture was a widely dispersed set of pre-Columbian Native American populations connected by a common network of trade routes from 100 BC to AD 500 in the Middle Woodland period. The researchers found evidence of a cosmic airburst at 11 Hopewell archaeological sites in three states stretching across the Ohio River Valley in the United States, which rained debris down into the Earth’s atmosphere creating a fiery explosion around 1,500 years ago...
