Cretatriacanthidae
Cretatriacanthidae is an extinct family of prehistoric marine Actinopterygii, ray-finned fish from the Late Cretaceous. It contains two genera, both known from southern Europe. Placed in the suborder Plectocretacicoidei alongside several other similar Cretaceous fish genera, they were long considered the earliest members of the extant order Tetraodontiformes. However, a 2024 study found that many of the alleged shared traits were also found among other acanthomorph lineages, and that other traits present within the Plectocretacicoidea, Plectocretacicoidei are not known from modern Tetraodontiformes. For this reason, it considered them instead as basal members of an expanded Acanthuriformes (containing Tetraodontiformes and Anglerfish, Lophiiformes as superorders, among others).

Tetraodontiformes
Tetraodontiformes (), also known as the Plectognathi, is an order of ray-finned fishes which includes the pufferfishes and related taxa. This order has been classified as a suborder of the order Perciformes, although recent studies have found that it, as the Tetraodontoidei, is a sister taxon to the anglerfish order Lophiiformes, called Lophiodei, and have placed both taxa within the Acanthuriformes. The Tetraodontiformes are represented by 10 extant families and at around 430 species overall. The majority of the species within this order are marine but a few may be found in freshwater. They are found throughout the world. Taxonomy Tetraodontiformes is a name first used for this order in 1940 by Lev Berg, the order was originally proposed in 1817 as the "''Les Plectognathes''", the Plectognathi. Cuvier divided this into two families ''"Les Gymnodontes"'' and ''"Les Sclerodermes"''. In 1940 Berg first used the term Tetraodontiformes for this order and this name is the curren ...
