Observations on the Attawapiskat Formation (Silurian) trilobites of Ontario, with description of a new encrinurine
The trilobite fauna of the Attawapiskat Formation of Ontario agrees with a late Llandoverian to early Wenlockian age assignment. This fauna is closely related to late Llandoverian and Wenlockian trilobite faunas from eastern Iowa and eastern Greenland. The numerically dominant trilobites of this fau...
