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.

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.

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.

This one of a kind Spinosaurus tooth fossil specimen has a long, narrow crown with a dark brown to near-black enamel tip and a broad, heavily preserved root section. The tooth has a strong taper and slight curve, with the pointed end still intact and the upper half coated in light brown matrix and fossilized root texture. The contrast between the smooth enamel and the rougher root area makes the overall shape easy to read.

This specimen stands out for how much of the root area remains attached. The crown is slimmer and darker, while the base is chunky, textured, and still carries natural sediment and bone-like structure. That gives it a very raw, field-collected appearance. It looks less cleaned down than many Moroccan dinosaur teeth, so it still shows the fossilization process and surrounding matrix.

Spinosaurus teeth are known for their conical form rather than the flatter, blade-like shape seen in many other theropod dinosaurs. That shape is one of the reasons these teeth are so recognizable. This piece has a good display profile, an intact point, and enough natural preservation to make it feel substantial and unmistakably prehistoric.
