Stratigraphy
| Local section: | Kandik River | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Collection a composite from the "unnamed Upper Jurassic sandstone" unit of the Kandik River headwaters section. This succession is assigned a Portlandian=lower Tiithonian? age based on macrofossil biostratigraphy (Buchia mosquensis biozone). | |||||
Lithology and environment
| Primary lithology: | sandy siltstone |
| Secondary lithology: | silty sandstone |
| Includes fossils? | Y |
| Includes fossils? | Y |
| Lithology description: Mainly interbedding of sandy siltstone and silty sandstone. | |
| Environment: | marine indet. |
| Geology comments: No paleoenevironmental data reported; neritic. | |
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 |
| Museum repositories: | GSC |
| Collection method comments: Collection is a composite derived from Fig. 2 of Jeletzky (1978), and amalgamated from occurrences of individual taxa on composite columns for individual lithostratigraphic units. Collections presumably are reposited in the Geological Survey of Canada collections. | |
| Taxonomic list comments:Definately not an exhaustive taxonomic list; taxonomic nomenclature appears reliable. | |
