If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

A. Kouchinsky et al. 2009Anabarites species having internal moulds with triangular transverse cross-section and deep narrow grooves; the rhomboidal transverse profile of the lobes becomes rounded at the apical part of the mould (see Fig. 2G–H).

DESCRIPTION. Slightly curved internal moulds with three deep narrow grooves. Lobes have a rhomboidal or triangular transverse profile (Fig. 22D, F). The grooves become shallower towards the apex (Fig. 22A–C, E). In this direction the lobes also acquire a rounded shape (Fig. 22E, G–H).
