It’s possible that the microclimate gradually changes from year to year. So maybe for a while there will be enough rain in one area to sustain trees, then things will change and they will die. And dead trees can last a very long time in a not, dry climate. They won’t get eaten by insects or fungus easily, so they might very well be from a time when the Great Desert was fertile. Anyway, a quick Google search shows that there appear to be dead trees in the Sahara and Namib deserts.
