Rare dinosaur eggs found in Narmada Valley
Context
A group of Indian researchers found rare cases of fossilised dinosaur eggs —among 256 newly discovered eggs from the Narmada Valley.
About
About the study:
- The findings of the study are published in the journal PLoS One January 18, 2023.
- The discovery suggests that Titanosaurs — one of the largest dinosaurs to have roamed the Earth — displayed a notable reproductive trait unique to modern-day birds.
- The egg has two yolks; this feature can be seen in birds, suggesting they share similar reproductive traits.
- The eggs found measures 15-17 centimetres in diameter.
- They were found during field investigations in the Dhar district of Madhya Pradesh between 2017 and 2020.
- They are found in Lameta exposure (is a sedimentary rock formation known for its dinosaur fossils).
- The eggs belonged to six species, suggesting a higher diversity of these extinct giants in India.
