Based on the length of its skull (95 mm), Sanajeh may have measured 3.5 meters in length from head to tail. Its vertebrae have well-developed articulations, which is a common feature of all madtsoiid snakes.
Sanajeh is a member of the family Madtsoiidae, which also includes two Australian genera of extinct snake that lived in the Cenozoic. Below is a cladogram based on the 2010 description of Sanajeh showing its relationship with other snakes:
The skull, jaws, and vertebrae of Sanajeh were discovered in rocks of the Maastrichian-age Lameta Formation in Gujarat, India. The fossils were described in 2010.
Sanajeh was found preserved next to a clutch of eggs from a sauropod dinosaur, and coiled next to a crushed egg. The snake was probably preying on the clutch and eating the hatchling dinosaurs.
