Comments to Middle Miocene closure of the Central American Seaway
A.G. Coates, Robert F. Stallard
2016, Science (348)
In a recent paper proposing an early (mid-Miocene) closure of the Central American Seaway (CAS), Montes et al. 2015 (1) disregard existing paleogeographic data that invalidate Panama as a source for zircons, and inappropriately ignore the evidence for trans-isthmian marine connections until 4-3 Ma. They also fail to cite previous...
