A team of researchers from the University of Delhi has discovered a unique set of fossilised dinosaur eggs, with one egg nesting within the other.


What are the observations?

  • While eggs-within-eggs are a rare phenomenon, they are so far known to occur only in birds and never known in reptiles. Until this discovery, no egg-in-egg fossil egg was found in dinosaurs and other reptiles such as turtles, lizards and crocodiles.
  • The findings talk about the “egg-in-egg” phenomenon in a titanosaurid dinosaur egg found at Bagh in Madhya Pradesh’s Dhar district . The new discovery of an ovum-in-ovo egg, brings out newer connections between reptilian and avian evolution.
  • Dinosaurs of the Sauropod family were among the largest land animals that ever lived and widespread millions of years ago in the territory that is now India. Fossils of these animals have been found in Gujarat, Madhya Pradesh and Meghalaya.
  • The Upper Cretaceous Lameta Formation of Central India is long known for its dinosaur fossils (both skeletal and egg remains).
