Chlorophthalmus udovichenkoi is an extinct species of Chlorophthalmus that lived during the Selandian stage of the Palaeocene epoch.
Etymology
The specific epithet of Chlorophthalmus udovichenkoi honours the scientist N. I. Udovichenko of Luhansk for their academic contributions to the study of prehistoric chondrichthyans of Ukraine.
Description
Chlorophthalmus udovichenkoi is diagnosed based on the fact that the taxon consists of an otolith with an undulating dorsal rim and a slight twist of its inner face outwards posteriorly. Its sulcus is narrow and long, and is distinctly inclined at angle of approximately 10°. Its cauda are slightly downturned, with their pointed tip reaching near to the postdorsal rim of the otolith.
Distribution
Chlorophthalmus udovichenkoi fossils are known from the site of Luzanivka in central Ukraine.[1]
