Echinidinium bispiniformum

bispiniformum Zonneveld, 1997, p.329,331,333, pl.4, figs.1–4; text-figs.7A–B ex Head, 2003a, p.171.  Holotype: Zonneveld, 1997, pl.4, figs.1–3.  The holotype is from ocean floor sediment and has a stratigraphic context; hence it may be treated as a fossil, its name not requiring a Latin diagnosis for validation (Head, 2003a, p.171–172).  This name was not validly published in Zonneveld (1997) since the generic name was not validated until 2001.  By fully citing the basionym, Head (2003a, p.171) validated the name Echinidinium bispiniformum.  Age: Holocene.
