Rank: species

Taxonomic discussion:

Ninadiacrodium caudatum is a distinctive and stratigraphically important taxon. To avoid any potential dilution of the specific concept a possibly closely related form encountered in the Comley samples is treated separately below as N. aff. caudatum. [Potter et al. 2012]

JWIP Catalog pages: N. caudatum * , D. caudatum *
