Stratigraphy
Formation:Ndalithoni Limestone
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Ndalithoni Limestone, which overlies the Koro Mbasanga volcanics (?Late Miocene) and is overlain by Recent alluvium and beach sands. AGE: Pliocene according to Ladd (1945), and stage "h" of Van der Vlerk. Assigned to a Pliocene age, although Ladd's assignment is founded on lyelian percentages. STRATIGRAPHIC POSITION: Unknown position within unit.
Lithology and environment
Primary lithology:shelly/skeletal poorly lithified calcareous conglomerate
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Conglomerate. Otherwise unknown lithology, though from limestone unit. LITHIFICATION: Presumed poorly lithified, given young age and extreme diversity relative to other underlying limestone units.
Environment:carbonate indet.
Geology comments: ENVIRONMENT: Unknown environment, though presumably shallow water carbonate.
Taphonomy
Size of fossils:macrofossils
Collection methods and comments
Collection methods:field collection
Reason for describing collection:biostratigraphic analysis
Collection method comments: COLLECTOR: H.S. Ladd and E.J. Hoffmeister, presumably with others. REPOSITORY: Unknown, possibly the Bernice P. Bishop Museum, Honolulu, Hawaii, or the USNM.
Taxonomic list comments:COMPLETENESS: Exhaustive for echinoidea, gastropoda, bivalvia, bryozoa, brachiopoda, and decapoda. NOMENCLATURE: Authoritative publication, although somewhat antiquated. Regular use of subgenera and species level identifications. Nomenclature vetted by A. Hendy (1/2007).
