This is a 8.8" long fossil turtle (Lytoloma elegans) skull from the Late Cretaceous phosphate deposits near Khouribga, Morocco. You see a lot of these on the market that are completely fake or composites but this is a real one with very little restoration. It's been meticulously prepared, reassembled and remounted back on the rock.
It comes from the phosphate deposits near Khouribga, Morocco. These deposits are mined for phosphate, one of Moroccos biggest exports. The fossils
are collected as a byproduct of the mining operations, saving them from certain destruction by the rock crusher.
