This is an exceptionally rare jaw section from Spinosaurus—one of the most iconic and enigmatic theropods of the Cretaceous period. Measuring 7.5 inches long, this genuine fossil was acquired over a decade ago at the Tucson Fossil Show from a reputable dealer known for authentic specimens.

Unlike many misidentified or fabricated pieces often seen on the market (especially crocodile jaws misrepresented as Spinosaurus), this specimen is a verified section of real Spinosaurus jaw.

The fossil includes three associated teeth, which were planted into the jaw for display purposes. As shown in the photos, the teeth were damaged during transport and will need replacement or repair. Despite this, the bone structure remains intact and displays excellent detail.

This is a collector-grade specimen of high scientific and display value—an increasingly hard-to-find piece from one of the largest predatory dinosaurs to ever live.
