Stromatoporoids of the Detroit River Group and Adjacent Rocks (Devonian) in the Vicinity of the Michigan Basin

"This report refines the basis for species level stromatoporoid taxonomy using large samples and relatively simple measuring and statistical techniques and evaluates the importance of these species for determining the geologic age of the enclosing rocks. Comparisons are also made of the species distributions in such varied environments as reefs, biostromes, and sedimentary carbonate substrates." --
