diagnosis
DIAGNOSIS. — Spongy discoidal spumellarians with surface completely or partially covered by a meshwork of equilateral triangular frames. The microsphere is shaped like triangular prism with 3 primary rays originating from its lateral edges. STRATIGRAPHIC OCCURRENCE. — early Early Miocene-Early Pliocene.
discussion
REMARKS The internal skeletal structure of Pentapylonium was already illustrated (Dumitrica 1991: pl. 5, figs 1 - 9; pl. 6, figs 1 - 9; pl. 7, figs 1 - 7). As reporting of Pentapylonium implicatum is limited to the upwelling regions off Peru, Oman and Somali (Nigrini & Caulet 1992), this family can rarely be observed in other regions. The overall appearance of Sphaeropylolena (Pylodiscidae) is similar to that of Pentapylonium, but the former fundamentally differs from the latter by the presence of a pylodiscid center (Zhang & Suzuki 2017: 38).
