Description
HETEROSTRACI? indet.
(Fig. 6I)
MATERIAL. — Specimen GIT 580-8: isolated tessera or platelet.
LOCALITY AND STRATIGRAPHIC HORIZON. — Same as specimens GIT n°580-1, 2, 3, 4, 6 and 7: locality (sample) 73, Tonnel’nyj Brook, south of De Long Strait, Chukotka; Lower Member (1) of Enmakaj Formation, Lochkovian.
DESCRIPTION ħis specimen is an isolated square-shaped element (either a tessera or platelet), partially broken, and with an altered surface. It bears a single, probably central, star-shaped tubercle (Fig. 6I). Because it is larger (c. 3.2 mm long for its preserved part) than all other tesserae that have been prepared from sample 73 of the Coast section, we suggest that it might correspond to a different taxon. Furthermore, with such a small sample (a single specimen), no thin section has been made, and thus its histology is not confirmed as being of a heterostracan.
