Lithology and environment
| Primary lithology: | bioturbation unlithified sandy siltstone |
| Includes fossils? | Y |
| Lithology description: The sediment exposed at this site consists of bioturbated, unconsolidated sandy siltstone, gently dipping to the west. Well preserved mollusks occur sporadically in the siltstone beds at this site as well as in beds exposed along the shore and in sea cliffs around the Tambac Bay area. | |
| Environment: | submarine fan |
| Geology comments: Shuto (1983, 1986) postulated that the siltstone beds in this area were deposited at a depth of ca. 300 m based on the lithology and associated fossil mollusks. | |
Taphonomy
| Modes of preservation: | body,original aragonite |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | good |
| Abundance in sediment: | rare |
Collection methods and comments
| Collection excludes: | some macrofossils,some microfossils | ||
| Collection methods: | surface (in situ),field collection,survey of museum collection | ||
| Reason for describing collection: | taxonomic analysis | ||
| Collectors: | De Ocampo, Wani et al. | Collection dates: | 1979, 2000s |
| Collection method comments: The specimen described here was collected by De Ocampo in 1979, and is found in the collection of the National Museum of the Philippines at Manila. Recent- ly, Aguilar, Zepeda, Kurihara, Kase, and Wani surveyed the stratigraphic position of the unit that yielded the specimen, and Hagino and Hayashi analyzed nannofos- sils and planktonic foraminifers to determine the age of the unit. | |||
