Eastmanalepes

Eastmanalepes primaevus is an extinct species of prehistoric jack fish that lived from the Lutetian epoch, of what is now Monte Bolca, Italy. It was originally described as a species of the jackfish genus "Caranx", of which it has a superficially similar outline to. It differs from "Caranx", and almost all other jackfish, in that it has very large, very pronounced scutes along its lateral line. According to Bannikov, "E. primaevus" is probably more related to the extinct jackfish genera, "Eothynnus" and "Teratichthys".
