Early–Middle Paleozoic ecosystem evolution and revolution (Part 2 of 2): an introduction
Papers included in this special issue have been derived and developed mostly from contributions presented at the 5th Annual Meeting of the International Geoscience Programme (IGCP) Project 591, held jointly with the 5th International Symposium on the Silurian System, sponsored by the International Subcommission on Silurian Stratigraphy (ISSS). The joint meeting was hosted by the Institut national de la recherche scientifique – Eau Terre Environnement (INRS–ETE) in Quebec City, Canada, including 3 days of scientific sessions, a pre-conference field excursion to the Gaspe Peninsula, a mid-conference excursion to the vicinity of Quebec City, and a post-conference excursion to Anticosti Island, Quebec. The goals of IGCP 591 and the joint meeting with ISSS were outlined in the first volume of this two-volume series (Jin and Melchin 2016).

The papers in this volume cover a range of topics in Early–Middle Paleozoic paleontology, stratigraphy, and geochemistry. Microfossils, particularly conodonts, …
