Stratigraphy
| Formation: | Cercado | Local bed: | 540 ft | ||
| Local order: | bottom to top | ||||
| Regional section: | Samba Hills | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Claystone. From unknown formation (Possibly Cercado, Gurabo or Mao) at the time of writing. Section of unknown thickness at 540 ft elevation. At 870 ft occurs an unfossilferous limestone bed, at 660 ft a bed of sandstone, at 600 ft a second sandstone bed outcroped, and at 540 ft the bed from which the collection was obtained. Probably equivalent to the Cercado Formation. | |||||
