Genus Tiksitheca Missarzhevsky in Rozanov et al., 1969
Type species: Tiksitheca licis Missarzhevsky in Rozanov et al., 1969; lower Cambrian ( upper Fortunian –lower part of Cambrian Stage 2); mouth of the Kugda-Yuryakh Creek , Kotuj River, Siberia, Russia .
Remarks.— Landing (1988) and Landing et al. (1989) discussed the generally similar, rounded-triangular, elongate conchs of Anabarites and Tiksitheca . These reports also noted the range of variability in the depth or even presence of longitudinal grooves in large collections of Anabarites tubes and/or moulds. For this reason, the two genera of which Anabarites was actually proposed by Voronova and Missarzhevsky (1969), were considered synonymous (Landing et al. 1989). In this report, the traditional distinctions of earlier named Anabarites and Tiksitheca species are however maintained (see also Kouchinsky et al. 2009).
