Discovery of some Early Carboniferous Radiolarians from North Perak and their significance

Twenty radiolarian taxa were identified from a chert sample collected from an outcrop of Upper Paleozoic rocks in North Perak. This is a new discovery of radiolarians in the area. The radiolarian assemblage represents the Albaillella deflandrei Assemblage Zone that indicates an age of Tournaisian, Early Carboniferous. Tournaisian radiolarians were found in many localities in Peninsular Malaysia and worldwide. Development of radiolarian chert during the Tournaisian was a worldwide event and is known as a hypersiliceous period. The radiolarian assemblage occupied paleobiogeographic province in the Paleo-Tethys ocean.
