Why not start a new month of the year with a newly-discovered dinosaur species? Meet Lokiceratops rangiformis, a fantastic exemplar of the rich ceratopsian diversity in Laramidia during the Campanian stage of the Late Cretaceous. A 6-meter-long centrosaurine ceratopsian with a 2-meter-long skull, it lived about 78.1 million years ago in what is now Montana’s Judith River Formation and appears to be most closely related to the slightly-younger Medusacertops lokii from the same formation and Albertaceratops nesmoi from Alberta’s Oldman Formation. The three species all together constitute the newly-created subgroup Albertaceratopsini within the Centrosaurinae.

Lokiceratops rangiformis was a ceratopsian dinosaur that lived during the Late Cretaceous (~78 million years ago) in what is now Montana, USA. Estimated at about 6.7m long (~22ft), it was one of the largest known members of the centrosaurine branch of the ceratopsians.

It had a unique arrangement of ornamentation on its skull, with no nose horn, two long brow horns, and a pair of huge asymmetrical curving blade-like spikes on the top of its square frill – some of the largest known frill spikes of any ceratopsian.

It lived in a swampy environment near the shore of the Western Interior Seaway, in an area that seems to have had an unusually high diversity of ceratopsians – along with Lokiceratops there were three other centrosaurines (Medusaceratops, Albertaceratops, and Wendiceratops), and one chasmosaurine (Judiceratops).

(There's also a possibility that it might not actually be a unique species. We know some other ceratopsians' faces changed quite drastically as they aged, so Lokiceratops could instead represent a fully mature individual of Medusaceratops.)

Another late cretaceous dino, Centrosaurus! Their central horn could curve backwards or forward, which gave them some cool variation!

A rooted dinosaur tooth of a triceratopsin, a Triceratops sp. or Torosaurus latus from the Hell Creek Formation in Powder River County, Montana, United States. Teeth of these chasmosaurine ceratopsids are unfortunately indistinguishable. Derived ceratopsians are known for their double root while more early diverging species like Leptoceratops gracilis only have one; in this specimen, the second root had been broken off. There are currently 3 or 4 triceratopsins described, Triceratops horridus, Triceratops prorsus, Torosaurus latus, and the possibly dubious Tatankaceratops sacrisonorum.

Microceratus gobiensis, one of the smallest ceratopsians, and Pentaceratops sternbergii, one of the largest ceratopsians. I made both of these simultaneously, and decided to include them in the same post.

Gwenn, the styracosaurus on the left, is a desaturated green with dark freckles & a dark brown horn. Peater, the styracosaurus on the right, is dark brown with pale freckles & a darker brown horn & frill spikes. Both of them have their eyes closed, and in the background are palm trees & ferns, as well as a seashell & orange sea star washed ashore. End of image description]

Gwenn belongs to & was designed by SollyRaptor on Primeval Age! Peater is my own character I designed myself.
