A synopsis is given of the most recent developments from micropalaeontological research on the coal-bearing Upper Carboniferous (Namurian C—Westphalian C) of Westphalia. The hope is expressed that a wider use of the technique of breaking down the mudstones into mud and isolating the fossils will, in conjunction with the important palaeontological results obtained in the English coal-basins, facilitate correlation between the Upper Carboniferous (Westphalian A to C) of England and Germany; also that the same technique will enable deep borings to be correlated in greater detail.
