| Areas of overlying sandy sediments were removed to expose the fossiliferous clay. |
| The section is very fossiliferous, with an abundant brachiopod, bryozoan, coral, and phacopsid trilobite assemblage. |
| The fossiliferous horizons occur in greenish to greyish siltstones and brown to black fissile shales associated with mollusc shells. |
| These rocks are thought to be Ordovician in age based on correlation with fossiliferous rocks at the same structural horizon near Nyalam. |
| The La Meseta Formation is the best exposed and most fossiliferous rock unit of Eocene age in Antarctica. |
| Conditions requisite for the original completeness of a fossiliferous series. |
