Sanajeh (meaning "ancient gape" in Sanskrit) is a genus of late Cretaceous madtsoiid snake from western India. A fossil described in 2010 from the Lameta Formation was found coiled around an egg and an adjacent skeleton of a 50 cm (19 in) long sauropod dinosaur hatchling. This suggests that the snake preyed on hatchling sauropods at nesting sites.
