What is "beothukis"

Beothukis mistakensis is a rare fossil frond-like rangeomorph, described from the Ediacaran of Mistaken Point, Newfoundland. It had been identified since 1992, referred in papers as a "spatulate frond" or "flat recliner", but not formally described until 2009. The original fossils from which the genus has been described are still in situ, but replicas are preserved at the Memorial University of Newfoundland and at the Oxford University Museum of Natural History.
