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.
