Abstract

Abstract An assemblage of Early Ordovician dichograptids has been discovered in a spotted slate from the Omeo Metamorphic Complex just north of Eskdale in northeast Victoria. Identifiable species present are Tetragraptus fruticosus (4 br.), T. acclinans, and Didymograptus cf. D. ensjoensis. Together these indicate an age corresponding to zone Bel of the early Bendigonian. They are therefore the first recorded fossils of pre‐Darriwilian age discovered east of the Howqua Zone in Victoria. The depositional history of the Wagga Trough is thus demonstrated to have commenced at least early in the Ordovician, rather than in the late Middle Ordovician as previously thought.
