Amphistium paradoxum (from Шаблон:Lang-el Шаблон:Transliteration, 'on both sides', Шаблон:Lang-el Шаблон:Transliteration 'sail', and Шаблон:Lang-el Шаблон:Transliteration 'extraordinary'),[1] the only species classified under the genus Amphistium, is a fossil fish which has been identified as a Paleogene relative of the flatfish, and as a transitional fossil.[2] In a typical modern flatfish, the head is asymmetric with both eyes on one side of the head. In Amphistium, the transition from the typical symmetric head of a vertebrate is incomplete, with one eye placed near the top of the head.[3]

Amphistium is among the many fossil fish species known from the Monte Bolca Lagerstätte of Lutetian Italy. Heteronectes is a related, and very similar fossil from a slightly earlier strata of France.
