Short summary
This study constitutes an attempt to analyze the variations in foraminiferal assemblages using the morphogroup approach in the Late Devonian. Our results show that both methods of estimating morphotype percentages, the traditional counting and the cumulated area methods, provide similar results, are highly correlated with each other, and provide similar relationships with paleoenvironmental proxies.
