Biology:Gasterorhamphosus
Gasterorhamphosus is an extinct genus of marine syngnathiform fish that lived during the Campanian stage of the Late Cretaceous.[1] It contains a single species, G. zuppichini from the Calcari di Melissano formation of Italy.[2]
It is the oldest known syngnathiform fish, making it distantly related to modern seahorses, pipefish, and trumpetfish.[3] It shares an especially close similarity to modern snipefish, and has sometimes been placed in the same clade as them (the Centriscoidea).[4] Others have found it to instead belong to the Aulostomoidea, containing trumpetfish and cornetfish.[3] However, other analyses indicate that it likely occupies a more stemward position within the group.[4] Despite this, studies have found it to at least group within the "long-snouted" clade of Syngnathiformes (the Syngnathoidei), making it the earliest known crown group-syngnathiform, and the oldest known definitive crown-group percomorph.[3][5]
