Spinosaurus Tooth - Fossil Specimen

Locality: Kem Kem Beds, near Taouz, Errachidia Province, Drâa-Tafilalet Region, Sahara Desert, Morocco

Era: Mesozoic
Geological Age: Late Cretaceous, Cenomanian 100.5 to 93.9 mya

Spinosaurus aegyptiacus was named in 1915 by the German palaeontologist Ernst Stromer, from a partial skeleton that the collector Richard Markgraf found in 1912 in the Bahariya Oasis of western Egypt. That skeleton was the only indisputable specimen of the species. It was destroyed on the night of 24–25 April 1944, when a bombing raid on Munich hit the museum that housed it, and only Stromer's notes, drawings and photographs survived.

Nearly a century later, Nizar Ibrahim and colleagues described a new partial Spinosaurus skeleton from the Kem Kem beds of southeastern Morocco, published in Science in September 2014. Comparing it with Stromer's surviving records, they concluded that Spinosaurus was at least partly aquatic, the first dinosaur known with such adaptations. Its nostrils sat far back on the skull, its hindlimbs were short, and its limb bones were solid, which would have helped with buoyancy control in water.

The Kem Kem beds form desert cliffs in the Moroccan Sahara. In the Cretaceous the area was part of a large river system, home to large sharks, coelacanths, lungfish and crocodile-like animals, along with giant flying reptiles and predatory dinosaurs.

This one of a kind Spinosaurus tooth fossil specimen has a long, narrow, gently curved profile with a dark brown crown that tapers cleanly to a sharp tip. The enamel-bearing portion is darker and smoother, while the upper half shifts into a lighter brown to tan fossilized root area with sandy matrix still attached. The base is naturally incomplete, which gives the piece a very honest, excavated look rather than an over-prepared one.

What stands out on this specimen is the contrast between the darker crown and the rougher, more granular root section. You can see natural wear, patchy preservation, and surface texture changes along the length of the tooth, especially where the enamel transitions into the root. It has the lean, conical shape associated with Spinosaurus teeth, and this particular piece has a strong display silhouette because the point is still intact and the curve is easy to read from multiple angles.

Collectors are usually drawn to pieces like this because they feel direct and real. This tooth has that appeal. It looks ancient, predatory, and unmistakably fossil, with enough natural texture and breakage to show its age without losing the overall form that makes it such a recognizable dinosaur specimen.
