9.7-Million-Year-Old Teeth Discovered in Germany Have Scientists Puzzled
Scientists in Germany say they've found ape teeth that are surprisingly similar to the teeth of an early human relative dating to millions of years later. As the Independent reports, the team of experts unearthed a pair of 9.7-million-year-old fossilized teeth that, they say, have some of the same features as the teeth of the hominid Australopithecus afarensis.
Scientists from the Natural History Museum in Mainz found the fossils a year ago in nearby Eppelsheim but have waited until now to publish their findings—partly because they weren't sure what to make of the puzzling discovery. Of the two teeth, a canine and a molar, the canine tooth bears a striking resemble to that from "Lucy," one of the first known ancient human relatives to walk upright, who lived in Africa some 3.2 million years ago.
"They are clearly ape teeth," researcher Herbert Lutz told local media in a press conference. "Their characteristics resemble African finds that are four to five million years younger than the fossils excavated in Eppelsheim. This is a tremendous stroke of luck, but also a great mystery."
They dated the fossils using the remains of an extinct horse which was found buried in the same spot. In their paper, the scientists describe the canine’s similarities to other remains found in the lower half of the globe, but they still don't have answers to many of the questions the report raises. They plan to continue examining the teeth for clues. The public will also have a chance to see the teeth for themselves, first at a state exhibition this month, and then at Mainz's Natural History Museum.
