Unique Titanosaur Egg-Inside-Egg Found in India

Field photograph of the pathologic ovum-in-ovo egg documented from the Lameta Formation of village Padlya, Dhar District, Madhya Pradesh, India. Two slightly partially broken circular eggshell outlines can be seen with broken eggshell fragments within. A crescent-shaped gap is characteristically present in the upper right part of the egg.

Paleontologists have found a fossilized egg within another egg — a condition known as ovum-in-ovo — of a titanosaurid dinosaur in central India. The 68-million-year-old find demonstrates that ovum-in-ovo pathology is not unique to birds but also present in dinosaurs. This underscores the fact that reproductive biology of titanosaurids and other sauropod dinosaurs is more similar to that of crocodiles and birds (archosaurs) than to non-archosaurian...

In the foreground, the unidentified abelisaurid described herein (right) confronts the spinosaurid Spinosaurus aegyptiacus (left center, with the lungfish Retodus tuberculatus in jaws) and the carcharodontosaurid Carcharodontosaurus saharicus (right center) while two individuals of the stomatosuchid crocodyliform Stomatosuchus inermis (left) look on. In the background, a herd of the titanosaurian sauropod Paralititan stromeri (left) warily regards these theropods and two individuals of the bahariasaurid Bahariasaurus ingens (far right) while a small flock of an undescribed pterosaur soars above. The vegetation is dominated by the mangrove-like tree fern Weichselia reticulata. Image credit: Andrew McAfee, Carnegie Museum of Natural History.
