Elopoides

Elopoides is an extinct genus of prehistoric marine ray-finned fish known from the Early Cretaceous of Europe. It contains a single species, E. tomassoni, known from the late Albian of Aube, France. It is thought to be a stem-group megalopid, making it closely related to modern tarpons.
It is known from a single, complete skull with a well-preserved endocast of the brain, allowing the morphology of the braincase to be compared with other, more basal ray-finned fish. Otoliths may also be preserved.
