Eomyctophum
Eomyctophum is an extinct genus of lanternfish that inhabited the Peri-Tethys region and later the Paratethys Sea from the Eocene to the Oligocene. It is the only member of the extinct subfamily Eomyctophinae, although Eokrefftia may also belong in it. Its remains are known from throughout eastern Europe & western Asia in both the Caucasus and Carpathians, and comprise both articulated skeletons and otoliths, suggesting it was a particularly common fish. The earliest known member of the genus was identified from the Early Eocene of Italy in 2025, millions of years earlier and further west than the other species.
