Mediterran Crisis

This article is not about the crisis in Spain, we just recover a little bit from this dip lately.
But About the mediterranean Sea crisis many millions years ago. 
I am not a earth scientific person,so you are reading this on your own risk!
But the reason why I put this on the blog is that; I find often fossil stones of sea shells  in the surroundings of our Finca Terra personas in the Comarca Priorat on a altitude of 700 meters!

fossils from the area.

A little googling and i find the reason: The mediterranean crisis.
A lot of years ago ( 6 million) the mediterranean sea  was cut of from the Atlantic ocean. And it dried out with a huge amount of sea salt left. A warm period at that time!  The have drilled in the past (around 1970)  and found 1000/1500 meters of salt layers under the mediterranean sea floor.
evaporation of the seawater from 1500 meters to zero.

In that time the sea level was much higher as it  now is. Otherwise i can not find those fossil stones at a attitude of at least 700 meters.
The time also changes and the Atlantic ocean become higher than the cut-off near Gibraltar.

So the mediterranean sea fill itself up. And the opening at gibraltar is a fact..

chalk layers in the ground at Terra Personas of old shelfs?
