Anchiceratops ornatus

More details coming soon...
Etymology
Anchiceratops is derived from the Greek "agkhi" (near), "ceras" (horn) and "ops" (face) because of its supposed position as an evolutionary stepping stone, close to both Monoclonius and Ceratops. We now know that Monoclonius is probably Centrosaurus and a centrosaurine, Ceratops is barely a dinosaur but allowed to anchor ceratopsia for posterity, and Anchiceratops is a chasmosaurine, not that close to either of them.
The species epithet, ornatus, refers to the ornate (flashy!) margin of its rectangular frill, edged with irregular bony projections and knobbly bits.
Discovery
The first Anchiceratops fossils were discovered along the Red Deer River in the Dinosaur Park Formation (Dinosaur Provincial Park) of Alberta, Canada, by Barnum Brown in 1912. The Holotype (AMNH 5251, housed at the American Museum of Natural History, New York) consists of the back half of a skull, including its long frill.
Estimations
Timeline:
Era: Mesozoic
Epoch: Late Cretaceous
Stage: Campanian
Age range: 80-73 mya
Stats:
Est. max. length: 5 meters
Est. max. hip height: 2 meters
Est. max. weight: 1.4 tons
Diet: Herbivore
Synonyms
Anchiceratops longirostris ("long snout") is based on a complete skull (NMC 8535) that Charles M. Sternberg discovered 20km north-west of Morrin in 1924 and described five years later. With a somewhat shorter skull (1.6m long) and an overall more gracile construction, this specimen is almost universally accepted as a female version of the more robust Anchiceratops ornatus.
