The titanosaurid sauropods dominated the Indian subcontinent T about 67 million years ago, thumping their pillar-like limbs and waving around their huge tails. It is well known that dinosaurs, birds and crocodiles are close cousins, belonging to the same sub-class of animals (archosaurs), and that birds actually originated from dinosaurs. Still, it is quite difficult to imagine that the towering titanosaurid sauropods were closer biologically to present day birds than reptiles. However, a rare fossil of an 'abnormal' dinosaur egg discovered at a village in Dhar district in Madhya Pradesh might help boost this perception and open up a new vista of study on dinosaurs.
The find of the first of its kind 'ovum-in-ovo' (one egg inside another) dinosaur egg by a team of Delhi University researchers has thrown open a possibility that as far as the reproductive syster went, the titanosaurid sauropods might have been closer to birds, rather than reptiles like crocodiles, lizards and turtles.
The details of the rare discovery were published on June 7 in Scientific Reports, an online publication of the internationally acclaimed journal Nature. The paper said abnormal eggs had been documented earlier in the case of birds, turtles and dinosaurs. However, till this latest find in India, no egg-in-egg cases had been reported in dinosaurs, or for that matter in any other reptiles, anywhere in the world.

Everybody knows what 420 means in the Indian context. But in American parlance it is something very different: four-twenty or 4/20 or April 20 denotes cannabis celebration; its cultural references are rooted in the hippie culture of the 1960s and 1970s.

The art of political protest
The past doesn’t always remain in the past. Sometimes, it emerges in the present, reminding us about the universality and repetitiveness of the human experience. Berlin’s George Grosz Museum, a tiny gem, is a startling reminder that modern political and social ills are not modern. Grosz lived through World Wars I and II, shining a torch into the heart of darkness in high-ranking men and women—who were complicit in the collapse of the world as they knew it.
