Spinosaurus Lower Jaw Segment With 6 Teeth + Replacement Tooth. Made famous in "Jurassic Park II," the enormous theropod dinosaur Spinosaurus, with a huge sail on its back, remains an enigmatic dinosaur, as no skeleton even remotely complete has been found. The most complete specimen (only about 20%) was destroyed during World War II. All that is available today consists of many teeth, a few claws, some vertebrae, and a very small number of jaw segments (no complete jaw exists). Thus, this 9 ½" long by 2 1/2 " wide lower jaw section with six teeth and a small replacement tooth is both an important and a dramatic fossil.
Spinosaurus was both larger and much older than T-Rex (80-100 million years old). The major difference between these two dinosaurs could be seen in their skulls and teeth. Spinosaurus' head was narrow and long like a crocodile with huge peg-like teeth, not serrated like a T-Rex. This lower jaw has six teeth ranging in size from ½" to 3" long. The largest two teeth are not broken, but the tips of the teeth have been worn down from usage. The teeth are different sizes because Spinosaurus grew new teeth when teeth were lost in feeding. Interestingly, a very tiny replacement tooth is growing in one of the sockets.
Found in the Kem Kem Valley near Taouz, Morocco (near the border with Algeria), this dramatic dinosaur jaw segment would be the highlight of any collection. Add $35 for domestic shipping.
