Ceratopsian Month #10 – Nasutoceratops titusi

The second centrosaur discovered in the southern portion of Laramidia, Nasutoceratops (“large-nosed horned face”) lived 75 million years ago in Utah, USA. It would have measured around 4.8m long (15′8″), and had very long horns, curving out to the sides and then twisting forwards into a shape that convergently resembles those of modern cattle.

It appears to have been part of a unique side branch of the early centrosaurs known as the Nasutoceratopsini, which had long brow horns, small nose horns, and only modestly decorated frills compared to their other relatives. This group also includes representatives from further north such as Avaceratops and several other still-unnamed specimens.

Its snout was short and deep, with an unusually huge nasal cavity – even for a ceratopsid – and shows evidence of pneumatic air sacs. Skin impressions were also found around its left shoulder, showing a pattern of 1cm (0.4″) hexagonal scales surrounded by smaller triangular scales.
