| The kukersite oil shale is composed of the stratigraphically widespread mat-forming cyanobacterium Gloeocapsomorpha prisca Zalessky. |
| It is stratigraphically complex, and the excavation and subsequent analysis required considerable patience and skill. |
| The new discovery represents the first record of a diplodocid for South America and the stratigraphically youngest record of this clade anywhere. |
| The Syn-Rift rocks in Block 1711 are stratigraphically similar to the Pre-Salt rocks of the Santos Basin of Brazil in the Upper Congo Basin. |
| The ranges of the stratigraphically significant species can be integrated with the ranges of other species from different environments. |
| The various datolite-bearing lodes are described stratigraphically from the uppermost to the lowermost lode in the series. |
