Dorsetichthys bechei

Description

Dorsetichthys looked like a herring, but it was not related to them. It had a single dorsal fin, a symmetrical tail, and an anal fin. It also had large eyes.

Taxonomy

D. bechei was traditionally a species of Pholidophorus. However, Arratia (2013) said it was distinct from the type species of Pholidophorus and created a new order and family for Dorsetichthys.
