Taxonomic remark Originally described as a large fossil diatom; treated as such in WoRMS (2013) and AlgaeBase (2021 version). From Knaust, 2020: Bactryllium, originally introduced as a potentially large diatom, was then recognized as a coprolite (Rothpletz 1913; H€antzschel 1962; Gramann 1966; Häntzschel et al. 1968; Fig. 10A). Potential producer(s). Bactryllium is interpreted as the excrement of gastropods (e.g. Rothpletz 1913). Allasinaz (1968) revised Bactryllium and, based on modern analogues provided by Moore (1931b), discussed its origin as faecal pellets of the bivalve Nucula. Gazdzicki (1974, 1977) attributed B. elongatum and B. ornatum to the activity of bivalves. Brustur et al. (1999) showed that the modern isopod Trachelipus troglobius produces faecal pellets with a morphology and size close to Bactryllium and concluded that Bactryllium was produced by isopods. [details]
