Lepidotes

Lepidotes (from  lepidōtós, 'covered with scales') is an extinct genus of prehistoric ray-finned fish. Fossils have been found in Jurassic and Cretaceous rocks. It is a member of the Lepidotidae and has long been called a wastebasket taxon. It was originally called Lepidotus.

 Description 
Lepidotes was 30 cm (12 in) long. It is one example of a fish that didn't have the upper jawbones attached to the jugal bone. Some fish still have this feature, such as carp from the family Cyprinidae. It had a scaly and slightly elongated body. It had shiny scales with just a few punctures. Lepidotes likely ate soft-bodied animals, as shown from stomach contents. It lived in both freshwater lakes and shallow seas.

 Taxonomy 

 Species 
Four species are known:

 †Lepidotes elvensis Blainville, 1818
 †Lepidotes gigas Agassiz, 1832 (type species)
 †Lepidotes semiserratus Agassiz, 1836
 †Lepidotes bülowianus Jaekel, 1929

 Synonyms 

 Lepidosaurus Meyer, 1833
 Lepidotus (former name)
 Serobodus Münster, 1812
 Sphaerodus Agassiz, 1833
 Plesiodus Wagner, 1863
 Prolepidotus Zeitschr, 1983

 Some species 

 Lepidotes gigas 
Lepidotes gigas is the type species of this genus. It is known from the Lower Jurassic of Germany.

 Lepidotes bülowianus 
Lepidotes bülowianus is another species of this genus. It is known from the Lower Jurassic of Germany.

 Reassigned species 
Lepidotes latifrons is now a species of Isanichthys. Most of the species have been reassigned to Scheenstia. As a result, only four species are found in this genus
