I have not found any information about the type of trees that are found in the fossil forests of the Tidikelt. However, given its appearance, it might well be a Cupressus and possibly Cupressus dupreziana, “Tarout” in Tamashek, now living only in the Tassili n'Ajjer but that, a long time ago, used to grow extensively in what is now the Sahara.
The second photo is of a living trunk of Cupressus, shot in the Tassili N'Ajjer.
More on Cupressus dupreziana and following pages.
I have also three other pages
on the subject of these
In those remote places, it is always nice to be able to have presents for the kids. However, when you make a gift, you must always give one to each of them, let it be a candy, a pencil, etc.
If you have not the same gift for each of them, it is better not to give anything.
If there are too many kids, do not give anything, you would most probably be unable to handle the gifts properly to each of them.
In the Sahara, you must carry plenty of water with you, much more than you will reasonably need. In case!
You will from time to time find along the trail someone with an empty can, begging for some water. It is nice when you can give him some.
You might have a breakdown or get lost. You will then have to stay away from an oasis longer that forecast.
Thus, each time you can make water, you must fill all your cans. Here in Aoulef, water was available at a well, Sudanese style. We had a bucket and a 20 meters rope, which is enough, most of the time. I remember that the water was very good.
It is always safer to have pills of disinfectant with you. However, in our different travels in the desert, we never used them and never got ill.
