Well-preserved and rich protoglobigerinid foraminiferal fauna were set free by concentrated acetic acid from hard "Ammoni1ico Rosso" limestones of Som Hill, Bakony Mountains. The studied series are well defined by ammonites indicating the Humphriesianum and Niortense Zones (Bajocian). The protoglobigerinid associations are diversified and dominated by large specimens, often reaching 400 μm in diameter, They comprise Conoglobigerina aff. dagestanica, Globuligerina oxfordiana (medium and large forms), G. aff. bathoniana (large form), and C. avariformis a so far few signaled species in the literature. Two new taxa are described: Globuligerina ? hungarica n.sp. with a very large last chamber, and. G. bathoniana gigantea n.ssp. a giant, high trochospired subspecies.
