| Popis: | Oncousoecia sp. (Fig. 19B) Material examined. VNMN-0271 (CT-42), on SEM stub with Tubulipora sp. Measurements. AzOr inside diameter, 0.11���0.16 (0.132 ��0.017) (n = 6). Ancestrular disk diameter, 0.264; ancestrular tube outside diameter, 0.159 (n = 1). Description. Young, ancestrular colony with 11 zooids; recumbent, zooids alternating in biserial lobes, though lobes perhaps wider later; peristomes not connate; exterior perforated by minute pseudopores. Zooidal orifices circular or transversely elliptical. Ancestrular primary disk circular, without pseudopores; ancestrula budding zooid distally and giving rise to another zooid laterally, apparently by peristomial budding. Remarks. Without a more fully developed colony and reproductive structures, this specimen can only tentatively be identified to genus Oncousoecia, and not at all to species.
