Dorsetichthys is an extinct genus of stem-teleost ray-finned fish from the Early Jurassic period of Europe.

Description

[edit]

Dorsetichthys was an elongated teleost that could reach up to 20 centimetres (7.9 in) long.[1][2] This fish had ganoid scales close to modern gars.[1]

Taxonomy

[edit]

The type species of Dorsetichthys, D. bechei, was formerly assigned to Pholidophorus, but Arratia (2013) recognized it as generically distinct from the Pholidophorus type species, placing it in the new family Dorsetichthyidae and new order Dorsetichthyiformes.[1]
