Description

Heteroconger astroblematicus was described in 2011 based on fossils of otoliths with moderately pointed, median anterior and posterior tips and a variable extended postdorsal region that sometimes contained a postdorsal angle, with the rims otherwise being smooth and having no angles. The sulcus on the convex inner face is inclined at angle of 10° to 15° and is somewhat deepened, in particular the ostium. Its cauda are short and slightly bent, containing a rounded tip.

Distribution

Heteroconger astroblematicus fossils are known from Ukraine. Specifically, its otolith fossils were discovered at Luzanivka, a fossil site in the Cherkasy district of central Ukraine. [1]
