Taxonomic remark From Butterfield et al., 1994: ... it is clear that Valkyria n.gen. was a complex, multicellular organism; however, a survey of possible modem analogues yields no convincing bauplan-level comparisons. The least sensational, though not obviously correct, interpretation would ally it to some of the complex algae that develop both axial fllaments of 'unlimited' growth and lateral fllaments of limited or determinate growth: e.g., Batrachospermum (Rhodophyta), Draparnaldia and Draparnaldiopsis (Chlorophyta, Chaetophorales), or Dasycladus and Batophora (Chlorophyta, Dasyeladales).
