Description

This Spinosaurus specimen has a set of characteristics which notably differentiate it from most of the teeth of this species which are usually on sale. It possesses a sharp and perfectly preserved tip. The quality of the enamel is unbeatable. The dazzling orangish color progressively acquires red shades towards the tip. It is the perfect example of the sharp morphology of the teeth of these efficient ichthyophaga dinosaurs. It does not possess any restoration or reparation. It is absolutely perfect.

The teeth with strong and vivid fossilization colors such as red, orange and black come from small paleochannels composed by thin layers, in the intermediate and upper stratigraphic levels (Red Sandstone Beds), from the Aoufous Formation (Kem Kem Basin, South of Morocco). The lithology of this body of sediment is characterized by the dominance of sandstones (also known as arenites) and fluvial gravel, of siliceous nature. Sometimes large concentrations of iron oxide are present, and then a small sample of that is usually present at the base of the tooth. These mineralizations are responsible for the wide range of beautiful reddish color tones, slowly drawn during millions of years via fossil-diagenetic processes. The complicated sedimentarian architecture of the layers where most large vertebrates are found makes the excavation methodology a real challenge. Sometimes the local miners have to excavate long tunnels that follow the distribution of the fossiliferous layer.

Most teeth of this species, due to its length and its stylized morphology, tend to lose the cusps during the eating process. After its death, they suffer mechanical wear during the sedimentarian transportation. Finally, during the fossilization, the lithostatic pressure also acts as a destructive agent for this delicate structures.
One of the difficult features to find in dentition samples of Spinosaurus is present in this piece. It is the preservation of the root (the part of the tooth without enamel, which occupied a lower position in the gum). Its preservation is complicated due to the hollow structure, which can collapse easily when even slight pressures are applied.

The different Geological Formations that make up the orography of the Cretaceous in the South East of Morocco have been mostly treated in an undifferentiated and not too accurate way by collectors, by Paleontology aficionados and by fossil dealers.

Historically, fossils dealers from all around the world have identified the dinosaur pieces from this sector as belonging to the Tegana Formation. However, in a formal way, most of the last published studies refer to other nomenclature in the description of the units and formations of the Lower and Upper Cretaceous.

That's why next we include an interesting link where the Aoufous Formation and the Ifezouane Formation are described, making reference to their age, geological history, sedimentology, stratigraphy and vertebrate assemblage. It includes a brief explanation of the stratigraphic concepts that have been established formally until today in the studies of this sector of Morocco.

This way, the precise stratigraphic understanding of the origin of the rests, as well as the sedimentological analysis, enables a better paleoecologic characterization of the environments where this amazing dinosaur assemblage lived.

The Only Real Specialist. A Certified Paleontologist in Charge

Many turn their hobby into business, they have an online store or sell in eBay. While that can be commendable, it can’t compare with a real expert, with years of academic formation, supervised field work experience, trained in the art of correct identification, detection of fakes, and a solid network of other accredited paleontologists to consult with.

The key facts are being able to guarantee:
Proper Fossil IDAccurate Scientific DescriptionLifetime Warranty

We do that, and in addition we provide a state-of-the-art uniquely numbered, 24/7 online verifiable, hologram-secured Certificate of Authenticity with all the specimens. It is a lifetime warranty: if new discoveries are made that modify the classification of the specimen or there is any inaccuracy, we will re-issue the certificate. On top of that, a 100% Money Back Guarantee in case you simply change your mind: no questions asked.
