Also known as Franja costera de Caldera
Where: Atacama, Chile (27.1° S, 70.9° W: paleocoordinates 27.4° S, 68.8° W)
• coordinate stated in text
• local area-level geographic resolution
When: Unit 1 Member (Bahía Inglesa Formation), Late/Upper Miocene (11.6 - 5.3 Ma)
• Rojo 1985 regarded the bed as Miocene
•Walsh and Naish 2002 uses Diatoms to state that it spans the Miocene-Pliocene boundary and extends as far as the middle Pliocene.
Environment/lithology: lagoonal or restricted shallow subtidal; coarse-grained conglomerate
•Charrier and Croft 2015: Según los autores mencionados, estos depósitos se acumularon en la plataforma continental en ambientes sublitorales a neríticos a profundidades comprendidas entre 0 y 500 m. Algunos niveles clásticos gruesos corresponderían a flujos de detritos provenientes de áreas emergidas
•Charrier and Croft 2015: Entre los sedimentos más finos exsisten intercalaciones de diatomitas, fosforitas y cenizas volcánicas retrabajadas (Rojo, 1985; Marquardt et al. 2000).
Size class: macrofossils
Preservation: original phosphate
