The Mediterranean completely dried out 4-5 million years ago which would necessitate that the passage at Gilbralter was blocked at that time.

correct, but that was a matter of lowered and then raised sea level, not a "breach" of the "dam" between Gibralter and north Africa as occured 65 million years ago. The postulated civilization destroyed by rising sea water may have occured as this author states, but it would be the result of the gradual rising of sea level brought about by the gradual melting of ice age glaciers, not the sudden event of the breach of the dam between the Med and Atlantic. That messes up this scenario as representing the "facts" in the Atlantis legend.

The breach event is apparently well established, geologically, with increcdible force being exerted to scour the floor of the Med by the jet of water from the breach. Some say the noise would have carried half way around the world. 65 million years ago who would have noticed? T Rex?

The below linked article will give you a sense of what I'm talking about regarding the Mediterranean. Although my qouted source is much newer, I cannot find it on the internet. Some say that during the Ice Age when the Mediterranean was much, much lower that the Nile Valley would have looked like the Grand Canyon of today.

Probably not. 65 Mya, T. Rex and most of his buddies were busy with the (hypothetical) K-T meteor.
