Age range of interval:0.77400 - 0.01170 m.y. ago
Stratigraphy
Stratigraphic resolution:group
Stratigraphy comments: LITHOSTRATIGRAPHY: No lithostratigraphy at the time of publishing, but likely that occurrences were derived from what are now understood as the Timms Point Silt (middle Pleistocene), San Pedro Sand (middle Pleistocene), and Palos Verdes Sand (late Pleistocene: AGE: Middle-Late Pleistocene (0.6-0.08 Ma) based on current understanding of chronostratigraphy for the units listed above. STRATIGRAPHIC RESOLUTION: List is derived from multiple stratigraphic units, so assigned to group resolution.
Lithology and environment
Primary lithology: unlithified "siliciclastic"
Lithology description: SPECIFIC LITHOLOGY: Unknown, but based on likely collecting localities would have included both sand and silt. LITHIFICATION: Unknown, but based on likely collecting localities would have been unlithified.
Environment:coastal indet.
Geology comments: ENVIRONMENT: Not stated, but based on current understanding of the units likely collected the list represents nearshore through inner shelf (mostly) and mid-outer shelf, coastal, siliciclastic depositional settings.
Taphonomy
Modes of preservation:body,original aragonite,original calcite
Size of fossils:macrofossils,mesofossils
Collection methods and comments
Collection methods:survey of museum collection
Reason for describing collection:taxonomic analysis
Collection method comments: COLLECTOR: Unknown, but likely multiple collectors at the California State Mining Bureau through late 1800s.
Taxonomic list comments:TAXONOMIC COVERAGE: Exhaustive for known fauna from region at the time, but unfortunately encompasses multiple localities and stratigraphic units. NOMENCLATURE: Antiquated, but resolved to species resolution.
