The Bet-Meir 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. It underlies the just slightly younger Amminadav Formation, and it is uncertain whether most of the paleobiota belong to one formation or the other.[1][2]

Paleobiota

edit

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