Sanajeh (meaning "ancient gape" in Sanskrit) is a genus of late Cretaceous madtsoiid snake from western India. A recently described fossil from the Lameta Formation has been found coiled around an egg and an adjacent skeleton of a 50 cm long sauropod dinosaur hatchling. This suggests that the snake preyed on hatchling sauropods at nesting sites.
