both male and female of this species are the same in coloration.

The islands Nanshiungosaurus is a rather unique species as they are the largest nocturnal animals on the island, though can only be found deep within the northern forest and are the most common prey item for the north's nocturnal tyrannosaur yutyrannus. These large herbivores have been observed not eating only plants but berries and small animals, which suggests an omnivorous diet. All this makes the islands Nanshiungosaurus an interesting dinosaur indeed.
