Six eggs containing the fossils of baby dinosaurs were recently found in Argentina. The fossils, which are remarkably well preserved, were found at Auca Mahuevo -- a site that has previously yielded similar fossils, dating back to about 65-145 million years ago. The fossils belong to the species titanosaurs -- members of the group of long-necked, long-tailed plant-eaters called sauropods.
The nearly-complete foetal skulls shed light on the evolution of some of the most notable features of sauropod dinosaurs' skulls. These skulls, a few centimetres across, are so well preserved that even the teeth are visible. The team behind the find was led by Luis Chiappe from the Natural History Museum of Los Angeles county.
