Short summary
Anticosti Island has a well-preserved rock succession throughout the Aeronian–Telychian boundary in the Llandovery Epoch, Silurian period, which includes two important biogeochemical events, the late Aeronian and the Valgu. This study suggests the position of this boundary in Anticosti based on the correlation of the island’s chitinozoan assemblages with the global occurrences, confirming both a remarkable preservation of upper Aeronian rocks and the record of the Valgu event.
