Dalatias is a genus of kitefin sharks that have lived since the Middle Eocene. It was thought to be a monotypic taxon with the type species, D. licha, considered as the only species until 2022, when Malyshkina and her colleagues described a new Middle Miocene species, D. orientalis. D. orientalis is from the Middle Miocene aged Duho Formation in Pohang, South Korea.[2][3]
