2.45" Spinosaurus Tooth In Rock - Dekkar Formation, Morocco

This is a 2.45" long, dark brown, fossil Spinosaur tooth from the Dekkar Formation in the Anoual Region, Morocco. The preservation in distinctively different than the more commonly seen Spinosaur teeth from the Kem Kem Beds several hundred miles to the South. It was prepared, still partially embedded in the rock. The base of the rock has been cut flat so it the tooth displays vertically on a hard surface. The tooth has several crack repairs.

In the past few years, these distinctive dark brown fossil dinosaur and reptile teeth have begun to appear on the market in limited quantities. They are found in Anoual Region of Morocco near Talsint. These teeth have almost always been incorrectly identified as Jurassic in age and are sometimes assigned wildly inaccurate identifications based on this incorrect age.

These fossil teeth are coming out of the Late Cretaceous Dekkar Formation. This formation is considered an equivalent to the Kem Kem Beds several hundred miles south, and the species appear to be the same or at least very similar. Part of the confusion is that very limited geological mapping has been done in this region of Morocco until recently. Most of the mapped formations were Jurassic, so people assume dDekkar was the same.

The teeth out of Dekkar have some different and interesting preservation compared to the Kem Kem Beds. The rock holds together better, allowing many teeth to be prepped in the matrix, something rarely seen with Kem Kem teeth.

Spinosaurus is one of the most spectacular and horrible creatures that ever stalked the Earth. Evidence suggests that it was semi-aquatic, so there was nowhere to escape from this fish and dinosaur-eating monster. It belonged to a genus of theropod dinosaur, and lived in what is now North Africa during the Cretaceous period, about 112 to 97 million years ago. The original fossil evidence of S. aegyptiacus from Egypt was destroyed in WWII. More recently, relatively abundant Spinosaurus fossils have been found in the Kem Kem Beds of Morocco, and there are almost certainly multiple species present.



Spinosaurus is currently the largest of all known carnivorous dinosaurs, even larger than T-Rex! While the exact size is debated ,recent finds and studies suggest Spinosaurus may have reached 41-59 feet in length and weighed in excess of 20 tons.

Spinosaurus had distinctive neural spines, extensions of the vertebrae that grew to at least 1.65 meters (5.4 feet) long. They were likely connected by skin to form a sail-like structure, but some authors suggest that the spines were similar in purpose and design to those of hump-backed mammals. Thermoregulation, display, and added weight while in the water are other likely explanations for this remarkable structure.

Spinosaurus's massive, nearly 6-foot skull is narrow like that of a modern crocodilian. Indicative of a piscivore, it had elongated jaws, conical, unserrated teeth, and raised nostrils. Isotope analysis of the teeth suggests a semi-aquatic lifestyle. It was likely a generalized and opportunistic predator, biased toward fishing.

Spinosaurus was a monster that lived among monsters. A picture of its life is pieced together with the gruesome contents of its meals and other macabre details of Cretaceous North Africa. Spinosaurus may have lived alongside similarly large dinosaurian predators such as Carcharodontosaurus, titanosaur sauropods, and the 33-foot long crocodylomorphs Stomatosuchus and Sarcosuchus.

A note on fossil Spinosaurus teeth:

Spinosaurus teeth are relatively common fossils, but large (3+ inches), well-preserved examples are rare. These large Spinosaurus teeth will often be heavily doctored. We’ve seen many examples where multiple partial teeth can been glued to together to create a larger fake tooth, or where enamel has been painted on. One giveaway to look for is a ring of sand around the middle of the tooth, usually glued on to hide a break. Sometimes this is a sign that multiple partial teeth have been composited, but other times it is used to disguise a badly done repair job.

While some teeth on FossilEra for sale have these types of repairs or restoration, we are careful to note it in the descriptions and they are priced accordingly.
