Ancient snake caught eating dinosaur

The fossilized remains of a 67-million-year-old snake found coiled around a dinosaur egg offer rare insight into the ancient reptile's dining habits and evolution, scientists said Tuesday.

The findings, which appeared in Tuesday's issue of the PLoS Biology journal, provide the first evidence that the 11.5-foot-long snake fed on eggs and hatchlings of saurapod dinosaurs, meaning it was one of the few predators to prey on the long-necked herbivores.

They also suggest that, as early as 100 million years ago, snakes were developing mobile jaws similar to those of today's large-mouthed snakes, including vipers and boas.

"This is an early, well preserved snake, and it is doing something," said University of Michigan paleontologist Jeff Wilson, who is credited with recognizing the snake bones amid the crushed dinosaur eggs and bones of hatchlings.

Dhananjay Mohabey of India's Geological Survey discovered the fossilized remains in 1987, and theorized that the snake — dubbed Sanajeh indicus, which means "ancient gaped one" in Sanskrit — had just arrived at the nest and was in the process of gobbling a hatchling emerging from its egg. The entire scene was "frozen in time" when it was hit by a storm or some other disaster.
