Bhopal, Jan 21: Paleontologists have reported a rare discovery of closely located dinosaur nests and 256 eggs of the herbivorous titanosaurs in the Narmada valley in Madhya Pradesh.

Researchers from the Delhi University and Indian Institute of Science Education and Research in Mohanpur-Kolkata and Bhopal have also reported discovery of ovum-in-ovo or multi-shell eggs in Bagh and Kukshi areas in Dhar district of Madhya Pradesh.

The findings were published in PLoS One research journal this week by Harsha Dhiman, Vishal Verma, and Guntupalli Prasad, among others.

A study of the nests and eggs has revealed intimate details about the lives of the long-necked sauropods that walked the region more than 66 million years ago.

"The eggs were found from the estuary formed at a place where the Tethys Sea merged with the Narmada when Seychelles had broken away from the Indian plate. The separation of Seychelles had led to the incursion of the Tethys Sea 400 kms inside the Narmada Valley," Verma, who works in the Higher Secondary School, Bakaner, Dhar district, told PTI here.

He said the nests found in the Narmada valley were close to each other. Generally the nests are located at some distance from each other.

Verma, considered the driving force behind a series of discoveries of dinosaur fossils in Narmada, said the reason behind multi-shell eggs could be the inability of the mother to find favourable conditions for laying eggs.

"In such conditions, the eggs remain in the oviduct and the shell formation begins again. There could also have been instances of a dinosaur dying before laying eggs," Verma said.

The eggs, which ranged between 15 cm and 17 cm in diameter, likely belonged to a number of titanosaur species.

The number of eggs in each nest ranged from one to 20.

"During the field investigations carried out between 2017 and 2020, we found extensive hatcheries of dinosaurs in Bagh and Kukshi areas in Dhar District, MP, notably from the villages Akhada, Dholiya Raipuriya, Jhaba, Jamniapura, and Padlya," the researchers said.

They said the region falls between the eastern most Lameta exposures at Jabalpur in upper Narmada in valley central India and Balasinor in the west in lower Narmada valley in western central India.

New Delhi, Nov 21: Karnataka Chief Minister Siddaramaiah on Thursday launched the Karnataka Milk Federation's (KMF) Nandini brand milk products in the Delhi-NCR market, pricing them marginally lower than competitors to gain a foothold in the region.

The cooperative will retail four cow milk variants, curd, and buttermilk from Friday, with competitive pricing that undercuts established players like Mother Dairy and Amul.

Cow milk will be sold at Rs 56 per litre, full Cream Milk at Rs 67 per litre, Standardised Milk at Rs 61 per litre, Toned Milk at Rs 55 per litre, and curd at Rs 74 per kg.

"We have surplus milk in the state. KMF along with Mandya Milk Union will market surplus milk of 3-4 lakh litres per day in Delhi-NCR," Siddaramaiah told reporters after launching the products.

The federation currently collects 100 lakh litres of milk daily, with local consumption at 60 lakh litres, leaving a surplus of 40 lakh litres for expansion into new markets.

However, the Chief Minister acknowledged the challenges of transporting milk over 2,500 km, which takes 50-54 hours.

There is a need to find new markets for surplus milk and gradually the KMF should be able to sell 5-6 lakh litres per day in Delhi-NCR, he added.

KMF Chairman LBP Bheemanaik assured that milk quality would be maintained during transit.

The federation has already partnered with 40 dealers in the Delhi-NCR region to facilitate sales, he added.

With a robust infrastructure of 26.76 lakh milk producers, 15,737 dairy cooperative societies, and 15 district milk unions, KMF has a turnover of Rs 25,000 crore and exports dairy products to over 25 countries.

State Animal Husbandry Minister K Venkatesh and Agriculture Minister N Cheluvarayaswamy were present at the product launch.
