Abstract

A site in Slope County, North Dakota has produced over 40 well preserved skin fragments as well as cranial and post cranial elements that identify it as a juvenile specimen of Edmontosaurus annectens. Among the impressions are tuberculate scales that range from 1 to 5 mm in diameter and are consistent with previously reported skin impressions. However, this specimen has produced six types of skin structures not previously described and include overlapping capped ovoid structures, a 9cm by 10 cm trapezoidal horn-like structure, and grooved scales all recovered from the caudal section of this specimen. Further investigation and preparation of the specimens will reveal new insights to this unique individual.
