Heteroconger astroblematicus is an extinct species of Heteroconger that lived during the Selandian stage of the Palaeocene epoch.
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.{{Cite journal |last1=Schwarzhans |first1=Werner |last2=Bratishko |first2=Andriy |date=1 July 2011 |title=The otoliths from the middle Paleocene of Luzanivka (Cherkasy district, Ukraine) |url=http://www.schweizerbart.de/papers/njgpa/detail/261/76171/The_otoliths_from_the_middle_Paleocene_of_Luzanivk?af=crossref |journal=Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen |language=en |volume=261 |issue=1 |pages=83–110 |doi=10.1127/0077-7749/2011/0154 |issn=0077-7749 |access-date=16 March 2025 |via=Schweizerbart Science Publishers|url-access=subscription }}
