Eoredlichia

Eoredlichia is an extinct genus of trilobite of average to large size (up to 12 centimetres or 4.7 inches long, or 20 centimetres or 7.9 inches when including the spine on the ninth thorax segment pointing horizontally to the back, that itself equals the main body length). It lived during the early Cambrian (late Atdabanian) in the Chengjiang fauna of Yunnan, China, and in Australia and Thailand. Eoredlichia is compounded of the Greek ἠώς (eos, dawn) and Redlichia, a later but related genus, so it means "early Redlichia". The species epithet intermedia means intermediate, indicating it is morphologically intermediate between other species. Eofallotaspis gives rise to Lemdadella, and thence to Eoredlichia and the other Redlichiidae. rdf:langString
