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.<ref name=mindat>{{Cite web |title=Amminadav, West Bank, Palestine |url=https://www.mindat.org/paleo_strat.php?id=859 |website=mindat.org}}</ref><ref name="mindat2">{{Cite web |title=Bet Meir or Amminadav, West Bank, Palestine |url=https://www.mindat.org/paleo_strat.php?id=1898 |website=mindat.org}}</ref> 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.<ref name="mindat2" /><ref name="Khalloufi 2010">{{Cite journal |author=Bouziane Khalloufi, René Zaragüeta-Bagils & Hervé Lelièvre |year=2010 |title=''Rhombichthys intoccabilis'', gen. et sp. nov.
