The Amminadav Formation is a Mesozoic geologic formation in the West Bank (Palestine). Pterosaur fossils have been recovered from the formation, in addition to several ray-finned fish and early snakes, most of which are known from the Ein Yabrud quarries.^[1]^[2] The formation overlies the just slightly older Bet-Meir Formation, and it is uncertain whether most of the paleobiota belong to one formation or the other.

Paleobiota

The majority of species here cannot be confidently assigned the Amminadav Formation, and some may instead belong to the older Bet-Meir formation.^[2]^[3]
