Parasemionotiformes

Parasemionotiformes is an extinct order of neopterygian ray-finned fish that existed globally during the Triassic period.

Many of the included genera are monotypic and most species lived during the Early Triassic epoch.

The latter represents a depauperate group today but used to be a diverse clade especially during the Mesozoic Era.

The only surviving members of the Holostei are the gars (Ginglymodi) and the bowfin (Halecomorphi).

[4] Parasemionotiformes belong to Holostei and are one of the earliest clades of the Halecomorphi (bowfin and its extinct relatives).

Parasemionotus labordei was the first described parasemionotiform
Albertonia cupidinia from the Early Triassic of Canada had large pectoral fins
Jacobulus novus was a small parasemionotiform
Watsonulus eugnathoides from the Early Triassic of Madagascar is one of the best known parasemionotiforms
Candelarialepis argentus from the Early Triassic of Nevada was a medium-sized parasemionotiform
