The world's oldest sea turtle fossil shows the ancient animal swam the oceans at least 120 million years ago, when dinosaurs still roamed the Earth, according to a recent analysis.
The now-extinct Desmatochelys padillai turtle skeleton was found in Villa de Leyva, Colombia, and is 25 million years older than the Santanachelys gaffneyi turtle from Brazil that previously held the record for the world's oldest sea turtle fossil.
The D. padillai specimen was dug up by hobby paleontologist Mary Luz Parra and her two brothers in 2007. However, it wasn't until Edwin Cadena, a researcher at the Senckenberg Research Institute and Natural History Museum in Germany, and James Parham, an assistant professor of geological sciences at California State University, Fullerton, inspected it that the fossil was determined to be the oldest sea turtle specimen in the world, dating back to the Cretaceous period, between 145.5 million and 65.5 million years ago.
