Abstract:
New findings of well-preserved Early Cretaceous planktonic foraminiferal assemblages from the Cismon core (NE Italy), Calabianca (NW Sicily), Lesches en Diois (SE France) and DSDP Site 545 (off Morocco) sections allow a better understanding of the morphological features of several taxa. This paper deals with the revision of the small, planispiral individuals that several authors include in the genus Blowiella Krechmar and Gorbachik. Comparison of morphological characteristics between Blowiella and the genus Globigerinelloides Cushman and ten Dam has resulted in retention of the latter as senior synonym of Blowiella. In fact, the morphological differences (i.e. the number of chambers in the outer whorl, the width of the umbilical area, and size and spacing of pores) used to distinguish Blowiella from Globigerinelloides cannot, in our opinion, be used in discriminating genera, but can only be applied at species level.
The small, few-chambered species of the genus Globigerinelloides retained here are Globigerinelloides blowi(Bolli), Globigerinelloides duboisi (Chevalier), Globigerinelloides maridalensis (Bolli), and Globigerinelloides paragottisi sp. nov. (=Globigerinelloides gottisi auctorum).
Stratigraphically, in the sections studied Globigerinelloides blowi and Globigerinelloides paragottisi sp. nov. are first recorded from the mid-Upper Barremian in the Cismon core and Calabianca section, while rare individuals belonging to Globigerinelloides maridalensis and Globigerinelloide duboisi occur intermittently from the Barremian/Aptian boundary and from the Lower Aptian, respectively. All of these taxa become more frequent and abundant just above the Selli Level (OAE1a, Lower Aptian), within the Leupoldina cabri Zone (Upper Aptian). Based on the DSDP Site 545 succession, all four globigerinelloidid taxa range up to the Ticinella bejaouaensis Zone (uppermost Aptian), with Globigerinelloides maridalensis disappearing at the base of the zone, followed in close succession by the disappearance of G. blowi, G. paragottisi and finally G. duboisi.
