Treatment

Genus Coniscala Boury, 1887

Type species. Scalaria angarensis Ryckholt, 1854 (type by original designation). Paleocene , Belgium.

Remarks. The sharp costae used as a diagnostic feature by Wenz (1940: p. 802) are not always present as illustrated by the Middle Danian C. faxensis Ravn, 1933 and the Selandian C. johnstrupi ( Mørch, 1874) , both from Denmark. The former has broad, rounded transverse ribs, while the latter features both rounded ribs and more costae-like ribs. The species are in all other regards typical members of this genus and the presence or absence of costae should thus only be used as a general diagnostic feature.
