‘Staggering number’ of titanosaur nests discovered in India reveals controversial findings about dino moms

About 70 million years ago, titanosaurs the length of school buses stomped through what is now west central India to lay their eggs by a riverbank. While these long-necked sauropods and the river are long gone, many of their nests remain intact, full of fossilized dinosaur eggs that reveal clues about how these massive herbivores nested and laid their eggs, and whether they took care of their hatchlings. 

The nests, in the Indian state of Madhya Pradesh, are packed together so tightly that it’s possible that titanosaur mothers abandoned their young soon after laying their eggs, so as not to crush their broods underfoot while navigating that narrow space, according to the study, published Jan. 18 in the journal PLOS One (opens in new tab).
