Lutetian genera

The moonfish of the genus Mene, the sole extant genus of the family Menidae, are disk-shaped fish which bear a vague resemblance to gourami, thanks to their lateral compression and thread-like pelvic fins. Today, the genus is represented only by Mene maculata of the Indo-Pacific, where it is a popular food fish, especially in the Philippines, where it is known as bilong-bilong, chabita, hiwas or tahas.

Formicium is an extinct collective genus of giant ants in the Formicidae subfamily Formiciinae. The genus currently contains three species, Formicium berryi, Formicium brodiei, and Formicium mirabile. All three species were described from Eocene aged sediments.

Buxolestes ("robber from Bouxwiller") is an extinct genus of semi-aquatic mammals belonging to the subfamily Pantolestinae within family Pantolestidae. Species in this genus lived during the middle Eocene. They are known from fossils found in the Bracklesham Group and Wittering Formation of England, at the Messel Pit in Germany and in Bouxwiller, France.

Incurvarites is an extinct genus of moths in the family Incurvariidae. It was described by Rebel in 1934, and contains the species Incurvarites alienella. The fossil was found in Baltic amber and is dated to Lutetian, Middle Eocene.

Eogeometer is a prehistoric genus of Ennomine geometer moths in the tribe Boarmiini. The type and only species is Eogeometer vadens, the specimen of which measured about , and was estimated to be 44 million years old, dating back to Eocene epoch. Both the genus and species were described by Thilo C. Fischer, Artur Michalski and Axel Hausmann in 2019 as the first geometrid caterpillar in Baltic amber.

Monosmilus is an extinct genus of prehistoric anchovy relative. It contains a single species, M. chureloides from the Middle Eocene (Lutetian)-aged Domanda Formation of Punjab, Pakistan.

Eolates ("dawn Lates") is an extinct genus of prehistoric lates perch from the Paleogene of Europe. It contains three species, two marine and one freshwater, known from the early-middle Eocene and Late Oligocene. left|thumb|Specimen of E. gracilis The following species are known:
