Farming for fossils in Morocco

Charles Underwood (UK) Fossil sites are generally the result of happy coincidence. It may be that this is the result of natural processes, when the sea or a river has eroded into cliffs of fossil bearing rocks. It could also be the result of human activity, where a quarry opened up for commercial reasons also happens to contain fossil-rich layers. However, it is rare for a fossil site to be made specifically for access to the fossils; and, when this does happen, access is usually restricted. However, there are exceptions. One of these is in the great Moroccan phosphate fields. Fig. 1. Meadows of spring flowers conceal the fossil-rich rock just below the surface. Strip mining for mineral phosphates is massive business in Morocco, providing the raw material for a vast proportion of the world’s phosphate fertiliser. Near the town of Khouribga, vast spoil heaps extend across the horizon and give an indication of the scale of the rock extraction going on behind them. These phosphate-bearing rocks are famous for their fossil content, and the cream and tan fossils from them can be seen for sale the world over. Unfortunately, access to the mines is very difficult and so, most of the time, collectors will have to satisfy themselves with what they can buy from dealers. While, purchasing specimens allows access to some really impressive finds, inevitably the fossils are out of context so their age is uncertain, and small and otherwise ‘unsellable’ fossils cannot be obtained. As some layers … Read More
