Me too. Reverse their 'anterior' and 'posterior' and Xidazoon stephanus is a
very good fit to certain of the Echiura, or spoon worms (2 circles of
posterior spines, pair of anterior spines, with proboscis lost or reduced). It
would also be useful to know what other fossils occur with it. The authors
The clear photos (f & g) of a well-ordered 'feeding apparatus' are not of the
new beast, but of the Pipiscius holotype. This somewhat misled me in my
first skim reading.
