Spinosaurus aegyptiacus tooth displaying an excellently preserved dark mahogany colour enamel to the killing tooth. Spinosaurus was a semi-aquatic predator, the development of the Spinosaurus grasping teeth was an evolutionary process of a marine specialist. The conical shape, although Spinosaurus has a more ovoid shape in cross-section, similar to the crocodilians of the same habitat and age. Crocodilian teeth of the period having a more round form in cross-section.
The tooth has a menacing curve and is of a very good size. Spinosaur fossil teeth of this location often demonstrates Iron red's and maroon tones, this specimen tooth is no exception, the colour being among the most attractive in the author's opinion. Although the tooth has suffered damage ion the fossil bed, this is evident in the illustration where the tooth has been refined in the upper crown section. It is yet a rare and impressive quality dinosaur fossil tooth. Spinosaurus dinosaur discovered in the Tegana formation, the province de Kasr-es-Souk in Kem Kem. This is the Northern Sahara, Morocco. Dating back to the Mesozoic era, early Cretaceous period, Cenomanian to Turonian stages 100 to 89 million years ago.
Topographical note; The best Spinosaur fossils are much in demand by collectors of Dinosaur fossils, many examples on the fossil market today are of poor quality, often incomplete. Understandably, many dinosaur teeth are damaged or worn, either due to life wear, the fossilisation or extraction process. Notably, the overall outcome of the condition of fossils much depends on the fossil site and the fragility of the fossil beds themselves, exposure to the elements, flooding which is becoming more common in certain areas of Morocco and in the desert regions the arduous nature of collecting in the far-flung corners of the Western Sahara ténéré. There are many influences and occurrences which play a role in the overall outcome of the extraction processes and condition of fossils. When considering the value of dinosaur fossils and the diminishing resource they are, particularly in this harsh collecting region and of the unique fossil dinosaur depositions, complete or undamaged teeth are limited in occurrence, it requires many collecting hours, weeks and months to discover fine quality specimens. This increases the value of every good find.
