Acrocanthosaurus

A small number of teeth and bones from a giant meat-eating dinosaur have been found in Maryland and Washington, D.C. Although we do not have enough fossils to tell exactly which predatory dinosaur this was, the distinctive shape of these teeth suggests that these fossils belonged to a relative of Acrocanthosaurus. Known primarily from Texas and Oklahoma, the 35 to foot long Acrocanthosaurus probably hunted sauropod dinosaurs, such as Astrodon.
