A large Spinosaurus tooth from a huge adult individual, the semi aquatic predators grasping teeth were an evolutionary tested grasping and 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 tooth is of a large bulky size from a massive jaw, has suffered some enamel loss evident in the upper crown section, this is evident in the illustrations above, and could be due to life wear or equally the rigours of the deposition of the fossil bed. The crown apical tip has definite life wear and this is an interesting morphological study aspect. The carinae cutting edges are mostly evident as are the ripple facets in the enamel around the body of the tooth crown. There appears to be dental disease apparent at the base of the labial face around the root stock-crown line, this is quite an interesting feature of study. Spinosaur fossil teeth of this location typically demonstrate dark red and dark maroon colour, this specimen tooth is no exception, the colour being among the most attractive in the authors opinion.
In the upper crown section at the apical tip there is loss of enamel, this all testament to the authentic state of this 100 million year old fossil tooth and could be life wear of the dinosaur or caused over millennia in the site, it is impossible to say with assurety. The interest here is the apical crown tip, which exhibits life wear, the tooth definitely worn down in the animals life time, while in the jaw of the predator and testament to the feeding habits of the individual, this is an excellent study tooth. 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 on the overall outcome of the extraction process's and condition of fossils. When considering the value of dinosaur fossils and the diminishing resource they are, particulalrly 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.
