This time we found a fossil of a leaf (fern).

when you look down to the makhtesh, you can see lots of black spots and hills. They are Vulcan's that exploded with-in the Nubian Sandstone.
When they did that they baked them and make them a little bit more resistant to erosion.
Its works like a time capsules. When been examined it can teach us about the climate that was here 150000000 y ago. And so you can see that this desert, was tropical shore with lots of water plants.
next time we will try to find an animal bones. :)
Thanks a lot to Amitai family.
