A large Spinosaurus tooth from a huge adult individual, the semi-aquatic predators grasping teeth were an evolutionary killing tool of a marine specialist. The conical shape, although Spinosaurus has a more ovoid shape in cross-section, is similar to the crocodilians of the same habitat and age. Crocodilian teeth of the period having a more round form in cross-section.
The complete and unbroken tooth of large and robust proportions from a massive jaw, which has suffered some enamel loss evident in the upper crown section. The crown apical tip has a definite life and appears to be been damaged by scavenging or predation of another carnivore, this an interesting study aspect. This is a huge tooth, an excellent quality of preservation and morphologically a very interesting study specimen dinosaur tooth with a rich mahogany patina to the fossilised dentin-enamel.
Spinosaurus dinosaur tooth 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.
