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.
