Overview

Name meaning

From Latin nasutus ("large-nosed") and Latinized Greek ceratops ("horned face"); titusi honours Alan Titus, palaeontologist at Grand Staircase-Escalante National Monument (Sampson et al. 2013).

Biology & evidence

What scientists think about how this animal lived, and how strong the evidence for each idea is.

Other

  • Laramidia was divided into northern and southern dinosaur provinces.

    Evidence level: Disputed

    Sampson and colleagues saw a southern centrosaurine lineage living at the same time as northern ones as strong support; others argue the differences reflect age and sampling.

    Evidence for / against · 1
    Evidence for
    • Phylogenetic inference · Centrosaurine phylogeny with Nasutoceratops

      Nasutoceratops is the sister taxon of Avaceratops in an early-branching centrosaurine subclade.

  • Nasutoceratops had an unusually large, air-filled nose.

    Evidence level: Direct evidence

    The nasal opening region makes up about three-quarters of the snout in front of the eyes, and the nasal bones hold an internal air space.

      A 1.8 m skull with a hypertrophied narial region (about 75% of preorbital length), pneumatic nasals, a short snout and rostrolaterally directed brow horns spanning about 40% of skull length.

      Specimen: UMNH VP 16800

  • Nasutoceratops had the longest brow horns of any centrosaurine.

    Evidence level: Direct evidence

    In the holotype they span about 40% of the skull length and reach almost to the tip of the snout.

Timeline

Lived from about 76 to 75.5 million years ago (Ma), within the Mesozoic era (252–66 Ma).

Periods: Campanian (83.6–72.1 Ma), Late Cretaceous (100.5–66 Ma)

Middle unit of the Kaiparowits Formation, about 75.97-75.51 Ma (Sampson et al. 2013, recalibrated after Roberts et al.); PBDB bins the collection as late Campanian.
