A spectacular but fossil whose significance was originally overlooked preserves an unusual example of behavior from the Late Cretaceous of India. As described by Wilson et al. (2010) (PLoS Biology 8:e1000322), the primitive snake Sanajeh indicus sits coiled over a sauropod nest, adjacent to several intact eggs, and, remarkably, a hatchling sauropod, strongly suggesting that this early snake preyed on either the eggs or the newly hatched young of dinosaurs. Skull morphological constraintes indicate that it was incapable of the enormous gape of modern boas and pythons, which severely limited the size of prey that it could take.
