Outlines evidence in support of the conclusion that the knolls of lower Carboniferous limestone in northern England which were originally characterized as "reef-knolls" (by Tiddeman in 1889), but which have also been interpreted as tectonic features, had a reeflike mode of origin. Corals are not abundant in the faunal assemblages of the limestone, and it is inferred that fenestellid bryozoans and calcareous algae may have played an important role in construction of the reef framework.
