A LARGE, High Quality Ankylosaurus osteoderm (bony armor plate) from the late Cretaceous of northern North America. Ankylosaurus magniventris was the largest Ankylosaur which grew to 30 feet and 17000 pounds, and a body covered with this bony armor. A complete body osteoderm plate from an adult Ankylosaurus. The bone is excellent quality with excellent color / patina. No cracks or restoration. Legally collected on private land in the Lance Creek Fm., Niobrara Co., Wyoming. Authenticity guaranteed. A collector's quality Ankylosaur osteoderm. I do not see large ostederms very often.
