The Atercurisaurus is a rare, dark-colored, jungle-dwelling stegosaurine stegosaurid from Skull Island. It measures 16-20 feet long. The last of their suborder, Skull Island’s small population of surviving stegosaurs clings to existence in ferny valleys deep in the interior of the island. Impressively armored with a studded hide, tall dorsal plates, and lethal abdominal and tail spikes, Atercurisaurus is not an easy lunch for predators, but competition with more successful herbivores on the island is causing their numbers to dwindle.
