The first report on Early Cretaceous Radiolaria from Myanmar

An Early Cretaceous radiolarian fauna is found from the Tagaung Taung area, central Myanmar. The fauna consists of the following species: Acanthocircus dicranacanthos (Squinabol), Stylosphaera squinaboli Tan Sin Hok, Hiscocapsa cf. subcrassitestata (Aita), Svinitzium cf. depressum (Baumgartner), Thanarla brouweri (Tan Sin Hok), Archaeodictyomitra mitra Dumitrica, Archaeodictyomitra apiarium (Rust), Archaeodictyomitra vulgaris Pessagno, Hemicryptocapsa cf. pseudopilula Tan Sin Hok, Hemicryptocapsa capita Tan Sin Hok, Holocryptocapsa hindei Tan Sin Hok and Cryptamphorella challengeri Schaaf. These species indicate clearly an Early Cretaceous age (Hauterivian), and therefore this is the first report on Cretaceous radiolarians from Myanmar.
