“…In Figure 12 the aperture is broken. The specimen is probably a Bolboforma with two chambers, as described by Daniels et al (1981). However, the second chamber would be significantly smaller.…”

Middle to upper Miocene sediments rich in well preserved specimens of Bolboforma have been recovered during Leg 80 (Goban Spur). This chapter discusses specimens recovered at Site 550, although specimens have been recovered at other Leg 80 sites also (Snyder et al., this vol.). The stratigraphic distribution of the specimens at Site 550 is compared with findings from other areas, including the Bay of Biscay (Leg 48), the Norwegian-Greenland Sea (Leg 38), and northern Europe. Species of Bolboforma show a great variability in morphology, probably as a result of preservation as well as ecological factors. According to their known geographic distribution, they seem to prefer temperate to cold water temperatures.One new species, Bolboforma pseudohystrix, is described.

“…Due to the abundance of well-preserved Bolboforma in the samples studied, we observed specimens that repre sented transitional forms between well-defined species, e.g., be tween B. metzmacheri and B. laevis (PL 1, Fig. 4 (Daniels et al, 1981).…”

“…Subsequently, 13 papers have documented Bolboforma from additional localities, including several DSDP coring sites (Table 1). Five additional species have been described, the stratigraphic range has been extended downward to the upper Eocene and upward to the upper Pliocene, and the geographic distribution has been extended from the eastern North Atlantic into the western North Atlantic and the western South Pacific (Rögl and Hochuli, 1976;Willems, 1976;Odrzywalska-Bienkowa, 1976;Bizon et al, 1977;Murray, 1979Murray, , 1984Doppert, 1980;Daniels et al, 1981;Szczechura, 1982;King, 1983;Müller et al, 1985;Echols, 1985;Poag and Karowe, 1986).…”

From 10 localities along the western margin of the North Atlantic Ocean, including Deep Sea Drilling Project (DSDP) Sites 106, 604, and 612, we have observed 11 species of presumed encysted calcareous algae assignable to the genus Bolboforma Daniels and Spiegler. These microfossils range stratigraphically from the upper Eocene to the Pliocene in this region and are found in inner sublittoral (30-50 m) to abyssal (4500 m) paleodepths. A transect from the Virginia Coastal Plain across the adjacent continental shelf to the abyssal plain indicates that bathyal sites contain the richest assemblages. Large populations from our samples reveal that variability in exterior morphology in conjunction with differential calcite dissolution may confuse taxonomic assignments and lead to false stratigraphic assumptions. We believe that careful analysis and comparison of large populations will lead to the widespread application of Bolboforma to interregional and global problems of biostratigraphy, paleoecology, and paleobiogeography.
