Hundreds of titanosaur eggs discovered in India

Recent work at the field in the center India found 92 nests with 256 fossil eggs titanosaursone of the largest dinosaurs that ever lived.

A detailed study of these nests allowed Harsha Dhiman of the University of Delhi and his colleagues to draw conclusions about the lifestyle of these nests. dinosaursin a study published in PLOS ONE.

It was a discovery

The authors identified six different types of eggs (oovids) in the Lamet Formation located in the Narmada Valley, indicating a greater diversity of eggs. titanosaurs than what is represented by the skeletal remains of this region. Based on the location of the nests, the team concluded that these dinosaurs They buried their eggs in shallow holes, like today’s crocodiles.

Certain pathologies found in the eggs, such as the rare case of egg-in-egg, indicate that sauropods titanosaurs they had a reproductive physiology similar to that of birds, and may have laid eggs sequentially, as seen in modern birds.

The presence of many nests in one area indicates that these dinosaurs they displayed colonial nesting like many modern birds, but the narrow spacing between nests left little space for chicks. dinosaurs adults, which supports the idea that adults abandoned newborn puppies to their fate.

Detailed information about reproductive habits dinosaurs they can be difficult to identify. These fossil nests provide a wealth of data on some dinosaurs the largest in history, and come from a time shortly before the age of the dinosaurs came to an end. The results of this study go a long way toward helping paleontologists better understand how dinosaurs lived and evolved.

Harsha Dhiman, lead author of the study, adds that the study “revealed the presence of an extensive breeding ground for sauropod dinosaurs.” titanosaurs in the study area and offers new knowledge about nest conservation conditions and reproductive strategies dinosaurs shortly before his disappearance.

Guntupalli V. R. Prasad, co-author and leader of the research team, adds that “along with nests dinosaur from Jabalpur, in the upper Narmada valley, to the east, and Balacinor, to the west, the new nesting sites of the Dhar region in Madhya Pradesh (central India), which cover an east to west stretch of about a thousand kilometers, are one of the largest breeding grounds dinosaurs peace.” (Europe Press)
