Neodiacrodium timofeevii
timofeevii (Shakhmundes, 1971, p.438–439, figs.1e–f [in published English translation]) Fedorova-Shakhmundes, 1976, p.95. Holotype: Shakhmundes, 1971, fig.1e (in published English translation, p.226); Fedorova-Shakhmundes, 1976, pl.1, figs.2,2a. Originally Acanthodiacrodium (Appendix A), subsequently (and now) Neodiacrodium. Fensome et al. (1990, p.33–34) accepted this name as validly published, at least in the published translation of Shakhmundes (1971), the original of which is in Russian. Shakhmundes (1971, p.438) cited "Fig.1d" as holotype; however, no illustrations appear to have accompanied that publication (or, at least, none is present in the copy held in the Geological Survey of Canada Library, Ottawa). In the published translation, fig.1e is listed as the holotype of Acanthodiacrodium timofeevii. Age: early Aptian.
