From the western side of the image, the eastern extremity of the Russian Federation reaches out towards the tip of Alaska. The International Date Line bisects the inter-continental gap and then veers south-west keeping St. Lawrence Island with Alaska...

What I HAVE been able to determine about the graphic is the people doing the captioning got things a little bass akwards. It's actually 180 degrees out of sync for example. North is south; Alaska is to the left(west?) and Russia is to the right(east?). Consequently, St. Lawrence Island appears to be NORTH of the strait; a line to the southwest would be a long time getting around to St. Lawrence.

Another item regarding your "caption" from your #88: Underwater Bering Strait:

Just curious Fred, are you a provocateur??? Or did I misunderstand your caption?

Your comment re the Bering Strait graphic illustrates my point to a certain extent, although in this case I didn't look at is closely as you did. The point I was trying to make was a 'break' in the 'landbridge' Beringia.

IF, when the Atlantic opened at the Fram Strait: #83 The authors attribute the change in Arctic conditions to the evolution of the Fram Strait into a wider, deeper passageway that allowed an inflow of saline North Atlantic water into the Arctic Ocean... my interest was drawn to that region.

I'm simply not taking the evolution of the Fram Strait into a wider, deeper passageway as an isolated phenomenon.

The Black Sea was also a fresh water body.

Now see this:

Spain/Africa.

Sediment samples from the bottom of the Mediterranean Sea that include evaporite minerals, soils, and fossil plants show that about five million years ago the Strait was topographically blocked and the Sea had evaporated into a deep basin far lower in elevation than the oceans.
