A 4. m thick section of silicified shales from Ban Phonxai in central Laos contains the radiolarians Trilonche davidi, T. hindea, T. minax, T. palimbola, Stigmosphaerostylus spp. and Ceratoikiscum ? sp. and the tentaculitids Homoctenus ultimus and Costulatostylionina vesca which together indicate a Frasnian age. This pelagic, deep shelf fauna from the Indochina Terrane is similar to that from South China and shows that tentaculitids may be common and biostratigraphically useful in radiolarian cherts and shales in South East Asia. This discovery probably necessitates mapping of the Late Devonian Phon Tiou Fm in this area which is currently mapped as the Early Carboniferous Boulapha Formation.
