The Ordovician-Silurian boundary at Anticosti

The Anticosti rock sequence in the Gulf of Saint-Lawrence displays a continuous series of sedimentary rocks that overlap the Ordovician-Silurian time boundary, indicated here by an arrow. The ice age at the end of the Ordovician Period had a harsh impact on the fauna living at that time.
