Olmoceratops the Mexican Chasmosaurine
"Olmoceratops" is my (unofficial) name for an heretofore unidentified taxon of ceratopsian dinosaur discovered in the Olmos Formation of northern Mexico back in 2011. So far only one of its brow horns has been uncovered, but at 95.2 cm in length, it likely belonged to a very large dinosaur (for perspective, the horns of Triceratops run only around ~80 cm long). "Olmoceratops" was almost certainly from the chasmosaurine branch of the ceratopsian family tree, but is not to be confused with the earlier-found Coahuilaceratops. I've chosen to reconstruct its appearance as similar to Triceratops's relative Ojoceratops.
Olmoceratops lived during the Maastrichtian epoch near the end of the Cretaceous Period. The Olmos formation from which it was uncovered has also yielded the remains of the hadrosaur Kritosaurus and tyrannosaurid teeth (T. Rex?). Analysis of fossil leaves from the area suggest a humid, tropical rainforest-like habitat, hence the jungle plants I've drawn around my Olmoceratops.
