An example of a nodosaur--a family of armored dinosaurs closely related to ankylosaurs--Acanthopholis was also protected by sharp spikes projecting from its neck and upper back. It was fairly small compared to others of its kind, weighing less than half a ton and measuring about 13 feet from head to tail. More about Acanthopholis
