Coelogaster is an extinct genus of marine ray-finned fish that lived during the early Eocene. It contains a single species, C. leptostea, known from the famous Monte Bolca site of Italy. [1] [2]

It is classified in the Anotophysi, and is generally considered a chanid of uncertain affinities, making it related to modern milkfish. [3] [4] [5] [6]

It was initially named without formal description by Louis Agassiz in 1835 as Clupea leptostea, alongside another fish known as Coelogaster analis. In 1905, Eastman officially described C. analis based on Agassiz's original name, and also described Clupea leptostea under the new genus Chanoides. A later revision found both these taxa to be synonymous, leading to the new combination Coelogaster leptostea. [5] [7]

White & Moy-Thomas (1940) suggested the genus name Eucoelogaster as a replacement, [2] as the previous genus name Coelogaster was already preoccupied by a weevil genus, but most authorities have since kept Coelogaster as the genus name, with the weevil genus instead going by Dietzella .

<i>Urolophus</i> Genus of cartilaginous fishes

Urolophus is a genus of round rays mostly native to the western Pacific Ocean and the Indian Ocean, though one species occurs in the Pacific waters of the Mexican coast. Müller and Henle erected Urolophus in an 1837 issue of Bericht Akademie der Wissenschaften zu Berlin. The name is derived from the Greek oura, meaning "tail", and lophos, meaning "crest". In Urolophus, the outer rims of the nostrils are not enlarged into lobes, but may form a small knob at the back.

<i>Gasteroclupea</i> Extinct genus of fishes

Gasteroclupea is a genus of prehistoric ellimmichthyiform fish that is distantly related to modern anchovies and herrings. It contains one species, G. branisai. It inhabited freshwater or estuarine habitats across South America during the Campanian and Maastrichtian stages of the Late Cretaceous period, and it briefly survived beyond the K-Pg boundary into the Danian stage of the Paleocene, making it among the few genera from its order to survive into the Cenozoic. Fossils of the genus have been found in the Yacoraite Formation of Argentina, the Chaunaca Formation, Santa Lucía Formation, and El Molino Formation of Bolivia, and the Navay Formation in Venezuela.

Dussumieriidae is a family of clupeiform fishes popularly called the "round herrings". It is now recognized by FishBase as a family in its own right; it had been considered to be a subfamily of Clupeidae. It contains two extant genera, and some potential fossil genera. Possibly the earliest record of the group is Nardoclupea from the Campanian of Italy.
