EOGUTTULINA-PALOMERENSIS, A NEW FORAMINIFERAL SPECIES FROM THE PLIENSBACHIAN-TOARCIAN BOUNDARY (EARLY JURASSIC) OF SW EUROPE

An Early Jurassic foraminiferal species, reported previously under the name of Eoguttulina sp. 1, from the uppermost Pliensbachian sediments of western Central Portugal, is formally described and its stratigrap hical distribution in SW Europe more precisely defined. The short stra tigraphic range (uppermost Pliensbachian, spinatum Zone, hawskerense S ubzone to lowermost Toarcian, tenuicostatum Zone, mirabile Subzone) an d the distinctive morphology of Eoguttulina palomerensis sp. nov. (Lag enina, Polymorphinidae) make it an extremely useful biostratigraphic m arker for this boundary interval.
