The fossils, also found in Patagonia, provide the first evidence that the whip-tailed diplodocid sauropods survived well beyond the Jurassic period, when they were thought to have been made extinct, the paleontologists said. This new species has received a name – Leinkupal laticauda – a combination of native Mapuche words for “vanishing” and “family,” and Latin words for “wide” and “tail”.
