Eodictyonella

Eodictyonella is a genus of rhynchonelliform brachiopods belonging to the extinct class Chileata. It is characterised by a non-strophic shell covered by a net-like ornament (Greek dictyon, a net). Like in most chileates, the perforation in the umbonal region of the ventral valve is covered by a colleplax. Eodictyonella is known from the Ordovician to the Lower Devonian.^[1]

Dictyonella Hall 1868

It had initially been described as Dictyonella Hall, 1868; however, this name proved to be a younger homonym of Dictyonella Schmidt, 1868, a sponge, so has been replaced by Eodictyonella Wright, 1994.^[2]

Eodictyonella belongs to the family Eichwaldiidae Schuchert, 1893 and to the order Dictyonellida Cooper, 1956. The latter is based on Eodictyonella under its former name. However, Dictyonellidae is a family of sponges.

Isogramma^[1] belongs to the same order, but its external aspect is rather different from Eodictyonella; Isogramma has a strophic shell.^[1]
