Eospinus daniltshenkoi is an extinct tetraodontid bony fish from the Eocene. Its fossils are from the Danata Formation lagerstatten of Ypresian Turkmenistan.

E. daniltshenkoi had four dorsal spines, three of which were on the anterior end of its dorsal side, and the first spine being placed between and below the eyes, almost like a long nose. It also had a pair of spines near the base of its caudal peduncle, and a spine in front of the anal fin.

In 2002, and confirmed again in 2003, Santini and Tyler erected the family Bolcabalistidae to contain both Eospinus and the Monte Bolca Bolcabalistes as close relatives of both triggerfishes and boxfishes. [2] The similar Moclaybalistes of Ypresian Denmark was originally also placed in Bolcabalistidae, too, in 2002, but then move it into its own monotypic family of Moclaybalistidae. [1]

<span class="mw-page-title-main">Tetraodontiformes</span> Order of fishes

The Tetraodontiformes are an order of highly derived ray-finned fish, also called the Plectognathi. Sometimes these are classified as a suborder of the order Perciformes. The Tetraodontiformes are represented by 10 extant families and at least 349 species overall; most are marine and dwell in and around tropical coral reefs, but a few species are found in freshwater streams and estuaries. They have no close relatives, and descend from a line of coral-dwelling species that emerged around 80 million years ago.

The Zeiformes are a small order of exclusively marine ray-finned fishes most notable for the dories, a group of common food fish. The order consists of about 33 species in six extant families, mostly deep-sea types. The boarfishes (Caproidae) have been previously included in this order though they are currently included in the Perciformes.
