Age range of interval:5.33300 - 3.60000 m.y. ago
Stratigraphy
Formation:Talparo Member:Matura
Regional section:Matura
Stratigraphic resolution:bed
Stratigraphy comments: Collection is from the Matura Sand and Clay Member of the Talparo Formation. The Matura fauna is considered to be of early Pliocene age and is probably slightly younger than the Courbaril fauna. The Matura shell bed has variously been attributed to the Pliocene (Guppy 1864, 1867, 1874; Maury 1925; Kugler 1953; Woodring 1966) or Pleistocene (Kugler 1936).
Lithology and environment
Primary lithology:shelly/skeletal,brown poorly lithified argillaceous,sandy "mixed carbonate-siliciclastic"
Includes fossils?Y
Lithology description: From blocks of highly limonitic, brown coquina with intercalations of clay and silt.
Environment:shoreface
Geology comments: The Matura fauna is a typical tropical, nearshore assemblage.
Taphonomy

Spatial resolution:parautochthonous
Collection methods and comments
Collection excludes:some macrofossils,some microfossils
Collection methods:selective quarrying,field collection
Reason for describing collection:taxonomic analysis
Museum repositories:PRI,USNM
Collection method comments: All material descibed in this report is reposited in the Naturhistorisches Mueum, Basel, or the USNM. Additional material collection from this unit is found at PRI.
Taxonomic list comments:Exhaustive for Mollusca. Several species of corals, bryozoa, lots of spines of echinodemrs, an Ophiuran (Berry 1935), fish teeth, otoliths, Balanus, and ostracods are present. Saunders in an unpublished report listed foraminifera from this locality.
