65,000 Years Of Beringia In Maps

The linked post shows images of how Beringia looked on a map at regular intervals over the last 65,000 years. The land bridge was more long lived than usually recognized.

Bison arrived from Siberia 130ka via Beringia, making the recent story about possible south California mastodon marrow scavenging slightly more plausible IMO.

It was probably a bit earlier than 130kya, but certainly there was a land bridge around that time. The big arguments against are that the land bridge involved a route farther north than any archaic hominins have been found, that it predates modern humans outside Africa (if they are to arrive in time to take the land bridge which is closer to 140kya), and that there is absolutely no other evidence of archaic hominins in the Americas when they should have been wildly successful in this virgin territory.
