Davichthys is an extinct genus of prehistoric marine ray-finned fish related to modern ladyfish. It is known from the Late Cretaceous of southern Europe, the Middle East, and North Africa. It is one of the earliest known elopids.

Taxonomy

The following species are known:

• †D. dubius (Davis, 1887) - Late Santonian of Lebanon (Sahel Alma) (=Osmeroides dubius Davis, 1887)
• †D. gardneri Forey, 1973 - Late Cenomanian of Lebanon (Sannine Formation)
• †D. lacostei (Arambourg, 1954) - Late Cenomanian of Italy (Scaglia Variegata Alpina Formation, Scaglia Bianca Formation) including Sicily (Argille Varicolori Formation), and Morocco (Jbel Tselfat) (=Holcolepis lacostei Arambourg, 1954)

Description

This fish was usually less than 15 centimeters long, and its appearance must have been very similar to that of the modern Elops . Like the latter, Davichthys had an elongated body with an oval cross-section, slightly flattened laterally. The eyes were rather large, while the mouth had robust jaws. The dorsal fin and the anal fin were rather small; the ventral fins were inserted far back, under the dorsal. The pectoral fins were placed low on the body. The caudal fin was very broad and strongly forked.
