Spinosaurus (meaning 'spine lizard') was an opportunistic predator who stomped through North Africa over 100 million years ago, eating small and large prey - including other dinosaurs. It is estimated to have been the largest of all known carnivorous dinosaurs, up to 60 feet long, weighing 20 tons. Our Spinosaurus Tooth was collected in Morocco and is preserved in a Riker Mount specimen box that can be easily opened to more closely examine this fossilized tooth. Box is approx 11 x 14 cm (4.25 x 5.375 inches). Tooth specimens will vary slightly in size, weight, and color.
