Abstract

Conodonts have been recovered from a section spanning the Ordovician–Silurian boundary at the eastern end of Anticosti Island. They indicate that the systemic boundary lies slightly above or at the top of a pisolitic limestone bed. This placement of the boundary compares closely with that based on a previous interpretation of brachiopod faunas from the same section, and also with the position of the systemic boundary based on conodonts elsewhere on Anticosti Island. The conodonts are the first to be reported from the eastern end of Anticosti Island.
