Where: Panama, Panama (9.1° N, 78.8° W: paleocoordinates 8.9° N, 77.5° W)
When: Chucunaque Formation, Late/Upper Miocene (11.6 - 5.3 Ma)
• From the text "In much of the Darien Province, the Chucunaque Formation of Shelton (1952) is Messinian in age (7.1–5.6 Ma), although Coates et al. (2004) suggested that it could be older than 9.4 Ma in the western part of their study area on the basis of calcareous nannofossil biostratigraphy. This age is consistent with 87Sr/86Sr dates of 10–9.5 Ma derived from calcerous Lindapectin shells that were deposited in association with the chondrichthyan remains"
Environment/lithology: deep subtidal shelf; lithified, silty, sandy lithology not reported
Size class: microfossils
