The prevalence of corals and fusilinids with grazing and stationary predatory habits combined with the higher relative abundance of benthic taxa that attached to a firm substrate is notable. In contrast, northern sites lack these taxa and are instead dominated by unattached benthic filter feeding taxa and elevated suspension feeders.Pennsylvanian fusulinids and calcareous algae from Sonora (northwestern Mexico), and their biostratigraphic and palaeobiogeographic implications.
