Burykhia is a Precambrian fossil genus from the White Sea region of Russia dating to 555 million years ago. It is considered of Ascidian affinity, due to the sac-like morphology and gill bag-like regularly perforated bands: if so, it could be the oldest ascidian fossil known as of its publication in 2012.[1] It is possibly related to the younger Ausia, another putative ascidian from the Vendian biota.[1] In the case of Burykhia, the narrow longitudinal vessels support affinity with the suborder Phlebobranchia.

Burykhia does not appear to have been colonial.[1]
