Spinosaurus aegyptiacus tooth 158mm long from the base of the rootstock to the crown tip. Excellent preservation after recent conservation here in the Lab in England. The monster dinosaur tooth crown exhibiting a good light toffee colour to the dentin enamel. The enamel displaying the archetypical patina of this location of the Red Sandstone beds of Kem Kem, Morocco.
Uniquely well preserved Spinosaurus dinosaur tooth and long root. Using the standards of collecting, desirability, quality and price, the first tick is assured. This dinosaur tooth is both desirable and rare due to the root being found intact in the fossil bed. A highly desirable and collectable dinosaur tooth from the classic fossil hotspot of the Red Sandstone beds of the Kem Kem formation, Western desert, S.E.Morocco.
The long curved tooth is an exceptional specimen, having the original and large root still attached, this is a very rare occurrence in our experience, all too often a large tooth of this type will sustain damage in the fossil process's and unfortunately, the roots become separated from the upper crowns. Here then is a very unusual opportunity to gain a Spinosaurus dinosaur tooth with elongate root.
Fossil bones and teeth often demonstrate iron-red or dark maroon tones due to the heavy content of iron in the fossil bed at Kem Kem. When the dinosaur was laid down eons ago heavy concentrations of minerals in the muds influenced the outcome of the colour of the fossilised remains. The environment was thought to be one of lakes, semi-tropical lagoons, so there was ample opportunity for the bones of the dinosaurs to be covered in an anoxic situation and bones be preserved. In this particular tooth, this iron influence can be seen as a pinkish hue in the rootstock, which is very attractive. In the upper crown, on the lingual face, the enamel is a slightly lighter in tone than on the labial face. On the lingual face, there has occurred in conservation some enamel infill where enamel loss occurred. This does not detract from the tooth and represents less than 10% of restoration in the whole conservation process in the lab.
The completeness of the tooth is a very good and an important scientific study piece morphologically speaking. Now conserved in the Lab in the UK it has a very stable strength and can be handled quite safely, this is also ideal for exhibiting the tooth as a display item. The specimen tooth can be forgiven the ravages of time, some fractures lines and old breaks now consolidated and strengthened, all bare testament to an archaic dinosaur fossil. An excellent specimen from the ferocious and renowned semi aquatic theropod predator. Spinosaurus larger than Tyrannosaurus rex, with great crocodile type elongated mandible and maxilla, the ornamental ribbed dorsal sail and huge ripping teeth and sickle claws which terrorised the Cretaceous scene around the shallow lagoons and on the open savannah of what we know today is the Saharan western desert of North Africa.
Many dinosaur teeth on the fossil market today are of poor quality, and often incomplete. Understandably many fossil dinosaur teeth are damaged or excessively worn due erosion in and out of the fossil bed, particularly if a fossil is exposed at the surface, also the extraction process can cause damage. The overall outcome and condition of these often fragile dinosaur fossils depend on many things, exposure to the elements and flooding which is becoming a more common problem in certain areas of the world where fossil layers are situated. The red beds of Kem Kem, near Taouz are no exception, the fragility of the beds and the erosive nature of the environs of the tiniri desert region at the site have an effect on the fossil hunters and collected dinosaur material.
There are many influences that play a role on the overall outcome and the value of dinosaur fossils and the finite resource they are, particularly in this region of the world and of this unique dinosaur deposition, complete and undamaged teeth are limited. It requires a much collecting time in the field to acquire good examples. This Spinosaurus tooth from a classic location fossil site, which recently has not been producing fossils of this quality very often, because as the beds become overworked, re-worked, it is an inevitability fossil seams become less productive. Presently this is acerbated by the withdrawal of free access to the area, for the indigenous Berbers whom work the fossil beds. Because where the best fossil beds lie there is political and military unrest over territorial disputes between Morocco and Algeria, making collecting fossils lately very sporadic at best.
