Eokrefftia ("dawn Krefftia") is an extinct genus of lanternfish that inhabited the seas around Europe and Australia throughout the Paleogene.[1][2] 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.[3]
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.[4]
