Shell single, 100-150 µ in diameter. Surface rough with 20-40 long-bladed spines having serrated edges. Pores elliptical, tending to be subdivided, about 11 µ in diameter, closely packed, 11 µ between pore centers. Large pores less than twice diameter of smaller pores.
Etymology: In honor of my husband, Bernard Blueford, Sr.
Extra details from original publication
Distinguishing features: Single shell with many long-bladed spines with serrated edges and elliptical pores with a tendency to be subdivided. Differs from Cladococcus abietinus by its unramified spines and subdi-vided pores and from Haliomma macradoras Haeckel by its pore shape a
Editors' Notes
Examination of Sites 77, 289, and 66 indicates that Acanthosphaera bernardi has a lower limit in core 77B-17, core 289-31, and core 66-5. In all cores, a small form with many pitted spines occurs near the base of the lower limit. No upper limit is distinguishable.[comment from RadWorld database]
