| These often overlie distal bayhead delta mouthbar facies, and commonly have a sharp erosive base. |
| Interadambulacral contact facets lie beneath the ambulacral and overlie tissue depressions for the longitudinal muscles that lower the arm. |
| Marls and limestones with fossils of an Eocene facies overlie the Cretaceous rocks on the Gabun. |
| Uppermost Permian and Triassic terrestrial sediments conformably overlie the terminal volcanic rocks. |
| This tidal delta origin is also supported by the observation that the succession does not overlie any regional incision surface. |
| One or more additional layers of shorter feathers may overlie the proximal parts of the flight primaries and secondaries. |
