Spinosaurus Aegyptiacus Tooth 98mm in length which has preserved extremely well. The authentic dinosaur tooth the enamel intact exhibiting a good tones of dark mahogany with deep reds, these colour identify instantly the deposition, the signature reds caused by a heavy concentration of iron ores or minerals which were prevalent in the fossil depositions when laid down in the Cretaceous sands or silts millions of years ago. This iron saturation is characteristic of the Kem Kem formation in Tegana. The conical dinosaur tooth exhibits a high sheen, enhancing the patina of the dentin-enamel. A menacing curvature, coupled with the good size.
The piscivore’s tooth displays a very interesting feature, considered an attribute. A smooth groove on the labial face, from the base of the mesial curvature, rising upwards towards the crown which can be clearly seen in our illustrations above. This signature is from another erupting tooth which has grown against this large mature healthy tooth in the Spinosaurus’s jaws and could well have been the contributory factor in the loss of this large tooth.
It is worthy of note that still today we don't know what causes the eruption of teeth in animals, including human young. The studies continue and many theories have been supported to later be rejected or dismissed. Notably The cushioned hammock theory developed by Harry Sicher around the 1930’s. The tooth growth displacement theory today still intrigues scientist, whether the tooth is displaced by bone growth around the tooth or jaw displacement, vascular cushioned ligament upward pressure and deposition tension from the tooth use. A conclusive study has not yet brought forth universally accepted agreement and so still remains undecided.
Conditions notes, the tooth has suffered a break just below the crown or tip, this now stabilised or reseated and showing fractures in the root, one of which may be a break and reseated. Nevertheless, the exceptional colour tones size and morphology make this an important find from this classic dinosaur fossil bed.
These points considered, this fabulous dinosaur tooth displays very interesting paleontological and scientific morphology contribute to making this specimen an important fossil find. From such dinosaur teeth and animal teeth, generally archaeological and palaeontological scientist can determine various attributes of the lifestyles of animals, mastication of food, if any method of feeding etc. Spinosaurus dinosaur teeth from the Tegana formation, in the province de Kasr-es-Souk, Kem Kem, are informative and can be studied, collecting pertinent details about the Cretaceous period when these dinosaurs were extant. These dinosaurs were the megafauna of the region which is now the Northern Sahara, Morocco. Dating back to the Mesozoic era, early Cretaceous period, Cenomanian to Turonian stages 100 to 89 million years ago.
