Geography
Country:New Zealand
Coordinates: 44.3° South, 176.0° West (view map)
Paleocoordinates:60.7° South, 132.8° West
Basis of coordinate:estimated from map
Geographic resolution:outcrop
Time
Period:Cretaceous Epoch:Late/Upper Cretaceous
Stage:Campanian 10 m.y. bin:Cretaceous 7
Key time interval:Campanian
Age range of interval:83.60000 - 72.10000 m.y. ago
Stratigraphy
Geological group:Pitt Island Formation:Kahuitara Tuff
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: Pitt Island Group includes Kahuitara Tuff, Southern Volcanics, and an unamed Haumurian limestone. The Kahuitara Tuff rests unconformably upon the Tupuangi Formation and passes into the Southern Volcanics without disconformity. THICKNESS: Maximum thickness of 225 m. AGE: Haumurian. Other collections are from the early Haumurian, so to avoid orphaning the collection is placed into the Campanian (=early Haumurian)
Lithology and environment
Primary lithology:pebbly,volcaniclastic lithified sandy tuff
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Volcanic, sandy, pebbly grit, compact. LITHIFICATION: Presumably lithified as stated to be "compact"
Environment:transition zone/lower shoreface
Geology comments: ENVIRONMENT: Inner shelf, open marine environment, near normal salinity, water depths ranging from 5-50 m.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection methods:field collection
Reason for describing collection:biostratigraphic analysis
Collection method comments: COLLECTOR: Unknown abbreviations (HMW, GWG, HRK) and M. Laird. REPOSITORY: Presumably reposited in the New Zealand Geological Survey collections (now GNS Science), Lower Hutt, New Zealand
Taxonomic list comments:COMPLETENESS: Exhaustive from macrofaunal groups. NOMENCLATURE: Not an authoritative publication, but identified by specialists and reported with modern nomenclature.
