Fig. 4

Palaeogeographical distribution of protoglobigerinids in Aaleno-Bajocian time. The numbers refer to the localities listed in Görög and Wernli (2003). Fat upright triangles refer to Bajocian age assemblages with thick- and thin-walled specimens; inverted triangles refer to the same for the Aalenian. Small upright triangles refer to assemblages with thin-shelled specimens, more or less restricted to shallow marine terrigenous facies
