Шаблон:Short description Шаблон:Automatic taxobox

Ischyodus (from Шаблон:Lang-el Шаблон:Transliteration, 'power' and Шаблон:Lang-el Шаблон:Transliteration 'tooth') is an extinct genus of chimaera. It is the most diverse and long-lived chimaera genus, with over 39 species found worldwide spanning over 140 million years from the Middle Jurassic to the Miocene.[1] Complete specimens of I. quenstedti from the Late Jurassic of Germany most closely resemble the genus Callorhinchus amongst living chimaera genera.[2] It is sometimes placed in the "Edaphodontidae", a unclearly defined group of chimaera with an uncertain position within the clade,[1] while other authors place it into Callorhinchidae along with Callorhinchus.[3]

Based on complete specimen, total length is 21 times larger than mesiodistal length of mandibular tooth plate. For example, I. bifurcatus with mandibular plate length of Шаблон:Cvt possibly belongs Шаблон:Cvt long specimen.[4]
