A critical reappraisal of the holotype of Beothukis mistakensis, a unique exceptionally preserved rangeomorph organism from Mistaken Point, Newfoundland, Canada

The holotype of Beothukis mistakensis in Mistaken Point, Newfoundland, is the only currently known specimen that can be definitely placed within the species. Morphological differences between the holotype of B. mistakensis and the well-constrained species plumosa suggest that the two are not congene...

Description
Summary:The holotype of Beothukis mistakensis in Mistaken Point, Newfoundland, is the only currently known specimen that can be definitely placed within the species. Morphological differences between the holotype of B. mistakensis and the well-constrained species plumosa suggest that the two are not congeneric and Culmofrons plumosa should be retained as a valid taxon as originally established. El holotipo de Beothukis mistakensis en Mistaken Point, Terranova, es el único ejemplar actualmente conocido que puede ser colocado definitivamente dentro de la especie. Las diferencias morfológicas entre el holotipo de B. mistakensis y la especie plumosa sugieren que ambas no son congéneres y que Culmofrons plumosa debería conservarse como un taxón válido tal como se estableció originalmente.
