Abstract

Two early Permian radiolarians, Pseudoalbaillella postscalprataIshiga, 1983 and Pseudoalbaillella sakmarensis (Kozur, 1981), are described from a calcareous nodule of the Permian siliciclastic succession distributed in north-central East Timor. The association probably indicates a Sakmarian (early Cisuralian) age. This is the first report of age-diagnostic Permian radiolarians from East Timor and demonstrates a potential source of well-preserved radiolarians of the Permian siliciclastic succession.
