Euthynotus

Euthynotus is an extinct genus of prehistoric bony fish that lived during the Toarcian. It is the most basal pachycormiform. The second most basal is Pachycormus. Fossil remains have been found in Europe.

Euthynotus had a slender body. The skull was quite long and narrow, with a slightly pointed snout. The dorsal fin was small and placed far away.

Euthynotus has two species:

• †Euthynotus incognitus Blainville, 1818
• †Euthynotus intermedius Agassiz, 1839

• Parathrissops Sauvage, 1891

Euthynotus incognitus is a species of Euthynotus. It is very much well-known.

Euthynotus intermedius is another species of Euthynotus. Unlike the other species, it's not well-known.

Like many pachycormiforms, Euthynotus was a predatory fish. The particularly long body of this fish made it very fast. It was a carnivore.
