Catalog entries: Ceratospyris hyperborea
type material: C. hyperboreaOriginal description: I have only seen very few individuals of this species. Its structure seems to be of precisely the same type as that of Dictyocircus clathratus, only that, on both sides of the sagittal ring, there is a further development of the network, which has become two complete domes, one on each side. The primary pores (nearest the sagittal ring) are polygonal the others being irregular roundish and oblong and varying considerably in size. The separating walls are strong, with here and there narrow, protruding points which form obliquely diverging narrow spines. There is also a rather plentiful number of similar byspines. All the spines are little prominent, to ¼ - ½ of the diameter of the sagittal ring.
Geological Range:
Last occurrence (top): Extant. Data source: Lazarus et al. 2015 - "R age group"
First occurrence (base): within Quaternary Period (0.00-2.59Ma, base in Gelasian stage). Data source: Lazarus et al. 2015 - "R age group"
