rdfs:comment	Spiclypeus is a extinct Genus of chasmosaurine Dinosaur that was closely related to Triceratops but in older rocks Spiclypeus has an estimated length of 4.5 to 6 metres and a weight of about three to four tonnes.[2] Spiclypeus is unique among Chasmosaurinae in having a wrinkled nose bone contact on the side surface of the rear projection of the premaxilla. Spiclypeus is also unique in having the trait combination of eye-socket horncores that project to above and sideways, all six epiparietals (frill horns) that are fused at their base, first two epiparietals pairs that curl down the frill surface on its front side, and third epiparietal pair that points back and towards the mid-line of the frill.[1]

abstract	Spiclypeus has an estimated length of 4.5 to 6 metres and a weight of about three to four tonnes.[2] Spiclypeus is unique among Chasmosaurinae in having a wrinkled nose bone contact on the side surface of the rear projection of the premaxilla.

However, it is morphologically similar to the dubious ceratopsid species Ceratops montanus from Judith River Formation and the dubious chasmosaurine species Pentaceratops aquilonius from the Dinosaur Park Formation (located just over the Canada–United States border and close in age) and in fact all three might represent a single species, which cannot be conclusively tested due to the fragmentary nature of the type specimens of these species.
