Time
| Period: | Paleogene | Epoch: | Eocene |
| Stage: | Ypresian | 10 m.y. bin: | Cenozoic 2 |

Stratigraphy
| Geological group: | Kekerione | Formation: | Te Whanga Limestone | Member: | Matanginui Limestone |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: THICKNESS: Matanginui Limestone is approximately 25 m thick at the type section. STRATIGRAPHIC RELATIONS: Matanginui Limestone is the lower member of the Te Whanga Limestone and conformably overlies the Red Bluff Tuff, and is unconformably overlain by younger strata. AGE: It is assigned an Waipawan-Bortonian local stage=Thanetian-Bartonian age based on biostratigraphy from combination of faunal groups. The particular collection is dated as Late Waipawan=Ypresian. | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal poorly lithified calcareous grainstone |
| Includes fossils? | Y |
| Lithology description: Soft, bryozoan-calcarenite. | |
| Environment: | offshore |
| Geology comments: Molluscan assemblages suggest warm, relatively shallow-water, undoubtfully oceasnic, with moderately deep water for part of the time (probably beyond shelf edge). | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection methods: | selective quarrying,field collection |
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: Collections reposited in Institute of Geological and Nuclear Sciences (New Zealand Geological Survey) collections. Collected by MAC (1977) | |
| Taxonomic list comments:Exhaustive for all faunal groups. Identified by P.A. Maxwell, D.E. Lee, J.S. Buckeridge, I.W. Keyes, and R.F. Jenkins. | |
