Chileata

Chileata Wiliams et al., 1996 is a class of rhynchonelliform brachiopods, characterised, among others, by the presence of a perforation in the umbonal region of the ventral valve, usually (partly) covered by a colleplax. They are known from the Cambrian to the Lower Permian.

Salanygolina may represent the chileate stem group.
