Description:

Africa, Madagascar, early Cretaceous (Lower Albian to Lower Cenomanian), ca. 112 to 97 million years ago. A quite sizable tooth from a Spinosaurus, one of the largest prehistoric carnivores, the head alone could be 1.68 meters (5.5 ft), easily accommodating about 64 of these knife-like teeth. The tooth is conical and nearly straight without serrations- characteristic of jaws that were built to skewer slippery prey in water- Spinosaurus were semi-aquatic piscivores that cruised along watery environments, hunting fish, and ambushing other dinosaurs that came to the shore to drink- similar tactics to modern day crocodilians. The upper enamel is a warm umber brown hue, and the lower two thirds are the root with a sandy beige and rougher surface from the sand and sediment the specimen was excavated from. Size: 4.41" L x 1.12" W (11.2 cm x 2.8 cm)
