Paleontologists in India have found 92 dinosaur nesting sites and 256 egg fossils for six different types of titanosaurs dinosaurs.
Paleontologists in India have found 92 dinosaur nesting sites and 256 egg fossils. The scientists made the discovery between 2017 and 2020 in the Narmada valley in central India. The discovery was the first of its kind for the Narmada valley, the researches say.this week, researches from the University of Delhi found the sauropod nesting sites in five villages in the Bagh-Kukshi area. Sauropods are large herbivores with long necks, such as a brontosaurus.

The discovery of ovum-in-ovo eggs – or eggs that have different layers besides the shell – shows that these dinosaurs had similar eggs to birds. However, their clutches were randomly placed, which suggest their nesting pattern was similar to crocodiles. The researchers believe the eggs were partially buried in a shallow pit, similar to modern crocodilians, and were incubated using and used solar radiation and geothermal heat.
The same nesting area was shared by different kinds of sauropods – which is similar to modern turtles and birds, which are known for colonial nesting behavior and have close spacing between clutches. Colonial nesting has been previously reported for sauropods.
