Anabarites hexasulcatus

- Anabaritidae

Anabaritellus hexasulcatus was named by Missarzhevsky (1974). Its type specimen is M71-2/69, an other, and it is a 3D body fossil. Its type locality is M71-2/69, left bank of the Olenyok River, 6 km downstream the Chuskuna Brook, which is in a Tommotian carbonate limestone in the Kessyusa Formation of the Russian Federation. It is the type species of Anabaritellus.

It was replaced with Anabaritellus tricarinatus by Landing and Murphy (1991); it was recombined as Anabarites hexasulcatus by Kouchinsky et al. (2009).

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. 2009Irregularly curved internal moulds having six grooves, first- and second-order. The latter are typically shallower than the first-order ones. In the grooves casts of growth lines are curved towards the aperture (Fig. 33O). As represented by the internal moulds, there is a range of variation from the different samples. The type specimen shows second-order grooves that are significantly less developed than the first-order ones (Fig. 33E–G). Forms from other samples have more prominent lobes (Fig. 33A) and some of them have deeper and broader second-order grooves (Fig. 33H).

Anabarites species characterised by internal moulds with six grooves separating rounded lobes (see Fig. 2N). Second-order grooves appear early on the lobes delimited by the first-order grooves.
