The attractive cream to dark mahogany brown tone is due to the minerals in the fossil layer which have effected the bone tissue. As the dinosaur skeleton is petrified and ultimately fossilised. The massive back bone, one of many held the strength of the dinosaur and in these illustrations one can imagine the bulk of the theropod stomping through the semi tropical forest and savannah of the Cretaceous. In the dorsal views the medullary cavity is deep and wide protecting the spinal cord, the thickness of the bone around the cavity is evidence of further protection. Here the hollow cavities within the surface of the body walls and the waisted body an indication of theropod evolving bones that reduce weight yet retain strength.
Unearthed in the red beds of the Kem-Kem fossil formation, a desert Hamada (plateaux), that rises in the border territories between Morocco and Algeria. The land of the indeginous Berber nomad of the western desert of the Northern Sahara. Cleaned, conserved and restored in a professional fossil laboratory in the United Kingdom.
Often Moroccan fossil diggers seal or cover over damaged or stressed bone finds with fixatives, or cosmetically coloured fillers. This can have a aesthetic negative result for any future collector or for scientific study, until at such time that these additives can be removed by a skilful technician. Cleaned back to the original bone surface. Thankfully this is usually possible in a professional laboratory using modern chemical restorers. Often the pasting over of what are assumed defects (palaeontologists, scientists and collectors find more interesting and appealing), becomes unappealing, often obvious, the fillers and additives creating more work. fortunately these field repairs can normally be undone and a good restoration and preservation can be carried out correctly.
The Carcharodontosaurus saharicus and Spinosaurid's would have co-exisited for around three million years during the Cenomanian stage of the cretaceous. This dinosaur vertebrae is from the same fossil horizon where Nizar Ibrahim made a significant Spinosaurid find, in a detective tale which unfolded in the southern part of Morocco. The bones which led to the eventual discovery of a partial skeleton Nizar finally identified in Italy and with the help of Paul Serrano from the museum of Chicago excavated on the slopes of the Red Beds Hamada in the western desert, the replica of that partial skeleton was composed of bones from various sources and went on display at the National Geographic Museum in Washington, D.C., The exhibition of Spinosaurus, Lost Giant of the Cretaceous Period in April 2015. This current exhibit was discovered in Morocco between 2013 to 2014 made its way to a European source and was secured by our fossil team.
