Also known as UF VP YPA088
Where: Panama (9.2° N, 79.6° W: paleocoordinates 9.0° N, 78.2° W)
• coordinate stated in text
When: Alajuela Formation, Tortonian (11.6 - 7.2 Ma)
• Comparison of the mean ratio with the global seawater 87Sr/86Sr curve for the Neogene [13] indicates a late Miocene age of 9.77 ± 0.22 Ma for this por- tion of the Alajuela Formation (Fig 5). The strontium dates also confirm a late Miocene age for the associated vertebrate fossils including the biochronologically informative horses and proboscidean Gomphotherium sp.
Environment/lithology: marine; sandstone
