Catalog entries: Ceratospyris borealis
Original description: Shell semi-globose, flattened and spinose at base composed of a coarse net-work
QTof strong rounded bars. Cells or perforations large, unequal. Diameter 5m to 6m. Height 4 to 5m.
Remarks on original description: The micro-unit employed by Bailey is 1/1000 of an English inch expressed in integers and fractions.
[Figure description. Differs from text in that there is a question mark after the generic name here but not after the generic name above the descriptive text.[comment from RadWorld database]
