349 Stromatoporoids from the Emsian (Lower Devonian) of Artic Canada PosterStromatoporoids from the Emsian (Lower Devonian) of Artic Canada BAP #349 Early Devonian limestones of Ellesmere, Bathurst, and smaller islands between them in the Canadian Arctic Archipelago contain a diverse fauna of stromatoporoid sponges. This fauna provides the best evidence in North America of the early recovery phase of this reef building group from a diversity low at the Silurian Devonian boundary, a recovery that lead to its diversity peak in

but of the forests that once covered almost all of northeastern North America
