Asociaciones de ostrácodos continentales de la Fm. Aguilar (Jurásico superior-Cretácico inferior, Cuenca Vascocantábrica)

The fossiliferous content of the Aguilar Fm. (latest Jurassic-earliest Cretaceous, Bascocantabrian Basin, N. Spain) consist mostly of ostracods, clavatoraceans, porocharaceans and gastropods, plus minor remains of fishes, crocodiles and turtles, a typical association of lacustrine palaeoenvironment....
