What is "eoarthropleura"

Eoarthropleura was a genus of millipede-like creatures which lived between the Late Silurian and Late Devonian periods. Fossils, mainly of cuticle fragments, have been found in Europe ( Rhineland-Palatinate, Germany and Shropshire, England) and North America ( New York, USA and New Brunswick, Canada). It is the earliest known member of the Arthropleuridea, and the oldest known terrestrial animal of North America.
