Anabarites hexasulcatus

- Anabaritidae

Taxonomy
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).

Diagnosis
ReferenceDiagnosis
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.
