Eokrefftia

Eokrefftia is an extinct genus of lanternfish that inhabited the seas around Europe and Australia throughout the Paleogene. Known only from its distinctive fossilized otoliths, it appears to be one of the earliest definitive fossil members of the lanternfish lineage. It may belong to the extinct subfamily Eomyctophinae.
The following species are known:

†E. paviai Schwarzhans & Carnevale, 2024 - late Oligocene of Italy
†E. prediaphus Schwarzhans, 1985 - late Paleocene of South Australia
†E. sulci - Early to Late Eocene of Italy, Middle Eocene of France

The otoliths of Eokrefftia can be easily confused with those of the extant lanternfish genus Diaphus, which are also present as fossils in the same deposits.
