| Insect palaeontology depends on assigning fossils to extant taxa usually on the basis of wing characters. |
| However palynology and vertebrate fossils have yielded reliable ages for a few basins. |
| A Pliocene age for the Siesta palaeosol and Nothofagus fossils has been inferred from diatom and palynological biostratigraphy. |
| The formation has yielded numerous fossils of stromatolites in addition to microfossils. |
| The percentage method has also been used in studying these kinds of fossils in other regions of the Indo-Pacific. |
| The occurrence higher in the succession of nummulites and neritic fossils indicates overall shallowing upwards. |
