Early closing between oceans The Central American Seaway, which once separated the Panama Arc from South America, may have closed 10 million years earlier than is believed. Montes et al. report that certain minerals of Panamanian provenance began to appear in South America during the Middle Miocene, 15 to 13 million years ago (see the Perspective by Hoorn and Flantua). The presence of the minerals indicates that rivers were flowing from the Panama Arc into the shallow marine basins of northern… 

Early Pliocene vegetation and hydrology changes in western equatorial South America

Abstract. During the early Pliocene, two major tectonic events triggered a profound reorganization of ocean and atmospheric circulation in the eastern equatorial Pacific (EEP), in the Caribbean Sea,

Quaternary glaciation and the Great American Biotic Interchange

Recent geological studies demonstrate that the Isthmus of Panama emerged some 10 m.y. earlier than previously assumed. Although absent today in Panama, Central American savanna environments likely

Paleoenvironments of the Upper Miocene Tuira Formation, Darien, Panama

Concurrent with the final collision of South America and Central America, sediments of the Upper Miocene Tuira Formation (Darien Province, southeastern Panama, Pacific side) were deposited 11.2–8.6

Miocene restriction of the Pacific-North Atlantic throughflow strengthened Atlantic overturning circulation

A new, continuous Nd isotope record shows that there was no direct intermediate water mass export from the Caribbean to the Florida Strait and thus, the Atlantic circulation could strengthen.

From Gondwana to the Great American Biotic Interchange: The Birth of South American Fauna

The Great American Biotic Interchange (GABI) is one of the biggest biogeographical events, which has shaped the modern South American fauna. It refers to several migratory pulses of continental fauna

Upper Pleistocene deposits from the Cauca Valley Depósitos del Pleistoceno Superior en el Valle del Río Cauca

The rise of the Isthmus of Panama is one of the major biogeographical events of the Cenozoic. It is a massive natural experiment in biological migrations, as lands formerly separated—South America

An early start for the Panama land bridge

It is proposed that the Central American Seaway, which separated South and North America, closed about 15 to 13 million years ago, more than 10 million years earlier than previously thought, with important implications for ocean circulation, climate, and biotic exchange.

Pliocene oceanic seaways and global climate

Pliocene Atlantic interhemispheric sea surface temperature and salinity gradients are presented in combination with a recently published benthic stable carbon isotope record from the southernmost extent of North Atlantic Deep Water to reconstruct gateway-related changes in the AMOC mode.



Closing of the Central American Seaway and the Ice Age: A critical review

[1] What role did the closing of the Central American Seaway play in enabling continental ice sheets to wax and wane over North America and Fennoscandia? A summary of relevant evidence presented here

A mechanism for freshening the Caribbean Sea in pre-Ice Age time

Many believe that the Central American Seaway closed near 4 Ma and that that closure led to increased salinity in the Caribbean Sea and stronger Meridional Overturning Circulation in the Atlantic,

Role of Panama uplift on oceanic freshwater balance

Comparison between planktic foraminiferal oxygen isotope records from the Caribbean Sea (Ocean Drilling Program [ODP] Site 999) and the equatorial east Pacific (ODP Site 851) suggests an increase in

Fracturing of the Panamanian Isthmus during initial collision with South America

Tectonic collision between South America and Panama began at 23–25 Ma. The collision is significant because it ultimately led to development of the Panamanian Isthmus, which in turn had wide-ranging

Consequences of shoaling of the Central American Seaway determined from modeling Nd isotopes

The Central American Seaway played a pivotal role in shaping global climate throughout the late Cenozoic. Recent geological surveys have provided new constraints on timing of the seaway shoaling,

Tectonic evolution of the Caribbean and northwestern South America: The case for accretion of two Late Cretaceous oceanic plateaus

It is widely accepted that the thickened oceanic crust of the Caribbean plate, its basaltic accreted margins, and accreted mafic terranes in northwestern South America represent the remnants of a

Arc‐continent collision and orocline formation: Closing of the Central American seaway

Closure of the Central American seaway was a local tectonic event with potentially global biotic and environmental repercussions. We report geochronological (six U/Pb LA-ICP-MS zircon ages) and

The seawater neodymium and lead isotope record of the final stages of Central American Seaway closure

The shoaling and final closure of the Central American Seaway (CAS) resulted in a major change of the global ocean circulation and has been suggested as an essential driver for strengthening of
