Chlorophthalmus udovichenkoi is an extinct species of Chlorophthalmus that lived during the Selandian stage of the Palaeocene epoch.
Etymology
[edit]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
[edit]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
[edit]Chlorophthalmus udovichenkoi fossils are known from the site of Luzanivka in central Ukraine.[1]
