Snakes are very abundant in the fossil record and include the second only record of blind snakes. Giant pythons of several different kinds were present.
Smaller pythons are found in the arid fauna and very large venomous snakes appear.

The remains of freshwater turtles and crocodiles were found in the older sites. The crocodiles belong to a completely extinct group called mekosuchines. Some mekosuchines may have been land-dwelling, which would explain their presence in cave deposits.
Turtles have been known the wander into caves as they move from water hole to water hole. Turtles only enter caves that are relatively easy to enter. Therefore, the ground surface during this time must have been considerably higher to allow these turtles to fall in big holes.
