A stray molar is the oldest known fossil from an ancient gibbon
While searching for primate fossils in northern India, paleontologist Christopher Gilbert noticed something small and shiny poking out of the dirt. It turned out to be a roughly 13-million-year-old molar from a small-bodied ape related to modern gibbons. The tooth is the oldest known fossil from a gibbon ancestor, says Gilbert, of Hunter College at the City University of New York. He and colleagues assigned the fossil, which was eroding out of previously dated sediment at a site called Ramnagar, to a new genus and species, Kapi ramnagarensis. This roughly 13-million-year-old molar tooth (shown from above) was found in India and is the oldest known fossil from a gibbon ancestor.C. Gilbert Until now, the oldest remains of an ancient gibbon species consisted of a small number of teeth found in China, which date from around 7 million to 9 million years ago. Possibly older fossils of a gibbonlike creature are controversial (SN: 10/29/15)....
