-
- Heliosoma? sp.
- Description:
Two concentric latticed spheres with 7-15 radial spines. Inner spherical shell
very thin walled, with 16 hexagonal pores on its circumference. Outer cortical
shell moderately thick walled, with 16-20 pores on its circumference, connected
with the former by several thin radial beams. Pores on the outer shell
subcircular to irregular in shape. Radial spines simple in shape, of unequal
length, irregularly spaced, projecting from the outer surface of the outer
shell. Diameter of the inner shell 30 µm, of pores of the inner shell 4-5 µm,
of the outer shell 100-110 µm, of pores of the outer shell 7-20 µm; width of
bars of the outer shell 2-5 µm; thickness of the outer shell 5-10 µm; length
of the radial spines up to 60 µm; thickness of basal part of the radial spines
up to 11 µm. In a specimen, two to five radial spines long (25-60 µm), the
other radial spines short (<25 µm).
- Remarks:
Inner shells and connecting beams are absent in most of encountered specimens,
possibly as a result of dissolution in sediments.
-

Included in this category are all specimens that consist of three concentric
latticed spheres, two of which are medullary shell, and six radial three-bladed
spines in three mutually perpendicular axes.

outer and inner cortical shells is 400 and 320 µm, respectively.
