Stratigraphy
| Formation: | Mzinene | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Mzinene Fm, which regionally overlies the Aptian-Albian Makatini Fm. THICKNESS: 30 cm thick bed within ~20 m section thickness. AGE: Albian V (=Late Albian?) based on ammonite biostratigraphy. STRATIGRAPHIC POSITION: Near the middle part of the section. | |||||
Lithology and environment
| Primary lithology: | concretionary,shelly/skeletal lithified siltstone |
| Includes fossils? | Y |
| Lithology description: SPECIFIC LITHOLOGY: Concretions with drifted bivalves, presumably with siltstone matrix based on lithologies of adjacent beds. LITHIFICATION: Lithified, assumed on the basis of facies descriptions from regionally dominant lithology, and figures from subsequent publications (e.g. Kennedy and Kinger 1977). | |
| Environment: | marine indet. |
| Geology comments: ENVIRONMENT: No detailed environmental data reported in text. | |
Taphonomy
| Modes of preservation: | body,concretion |
| Degree of concentration: | dispersed |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | good |
Collection methods and comments
| Collection methods: | field collection |
| Reason for describing collection: | taxonomic analysis |
| Museum repositories: | BMNH |
| Collection method comments: COLLECTORS: Collected by authors (W. Kennedy and H. Klinger) during 1970-1971. REPOSITORY: BMNH. | |
| Taxonomic list comments:COVERAGE: Includes ammonites, brachiopods, bivalves and gastropods. Abundance data may only apply to ammonites. NOMENCLATURE: Some of faunal list derived from authoritive publications, although for the most part this is not the case and taxa lack subgeneric or species-level designations. Nevertheless, authors are specialists and nomenclature appears fairly accurate and modern. | |
