Unusual ancient elephant tracks had our team of fossil experts stumped—how we solved the mystery

Over the past 15 years, through our scientific study of tracks and traces, we have identified more than 350 fossil vertebrate tracksites from South Africa's Cape south coast. Most are found in cemented sand dunes, called aeolianites, and all are from the Pleistocene Epoch, ranging in age from about 35,000 to 400,000 years.
