Abstract: A thinly bedded mudstone in the Langkap chert yielded a high diversity of radiolarian faunas. A total of 34 radiolarian taxa were identified. The presence of Albaillella comuta, Albaillella deflandrei and Albaillella undulata indicates the Albaillella deflandrei Zone oflate Tournaisian, Early Carboniferous. The radiolarian assemblage is very similar to those of Tournaisian of Germany and France. The similarity suggests that the radiolarian faunas occupied a similar biogeographic province in the equatorial regions of the Tethys.
