Burykhia hunti is a Precambrian fossil 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 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.[1] It is possibly related to the slightly younger Ausia, another putative ascidian from the Vendian biota in Namibia.[1] In the case of Burykhia, the narrow longitudinal vessels support affinity with the suborder Phlebobranchia.
