Taxonomic remark From Wisshak et al., 2019: Calciroda Mayer, 1952 and its type ichnospecies C. kraichgoviae Mayer, 1952 consists of ‘branched, horizontal tunnels running along the surface of organism hard parts, sometimes going vertically into the depth’ [original diagnosis, translated]. No holotype was designated, but the fgured specimens indicate an overlapping or cross-cutting relationship of individual tunnels instead of true branching, in addition to unbranched specimens. Plewes (1996: pl. 13, Fig. 5) studied Mayer’s type material and confrmed that ‘…both branching points and avoidance by tunnels can be seen…’; she regarded Calciroda as junior synonym of Talpina von Hagenow, 1840. In comparison with the recently rediscovered type material of Talpina and its revision (Wisshak et al. 2017: Fig. 2.1), the branched specimens of the dubious (because composite) and partly eroded trace fossil C. kraichgoviae can be assigned to Talpina ramosa von Hagenow, 1840, whereas the unbranched specimens belong to Trypanites solitarius (von Hagenow, 1840).
