Burykhia
''Burykhia hunti'' is a Precambrian fossil genus from the White Sea region of Russia dating to . It is considered of Ascidian affinity, due to the sac-like morphology and a series of distinctly perforated bands reminiscent of a tunicate pharynx. If ''B. hunti'' is a tunicate, it could be the oldest ascidian fossil known as of its publication in 2012. It is possibly related to the slightly younger ''Ausia'', another putative ascidian from the Vendian biota in Namibia.〔 In the case of ''Burykhia'', the narrow longitudinal vessels support affinity with the suborder Phlebobranchia. ''Burykhia'' does not appear to have been colonial.〔 ==See Also== List of Ediacaran genera
