ABSTRACT.
The sequence of conodont faunas in the Namurian of Belgium is described and compared with faunas of the same age in North America, western Europe and Japan. The faunas exhibit major changes within the Namurian in the Chokerian (H1), Alportian (H2) and Kinderscoutian (R1) sub-stages involving the appearance of new species and genera and the disappearance of many pre-existing ones. These changes take place at approximately the position of the Mississippian-Pennsylvanian boundary in North America. The palaeontology of these faunas is dealt with in detail and 47 species and sub-species have been recognised amongst which Angulodus simplex, Lonchodina bischoffi, Idiognathoides sulcata sulcata, Idiognathoides sulcata parva, Idiognathoides minuta, Streptognathodus lateralis and Gnathodus bilineatus bollandensis are considered new.
