Zuniceratops

Wolfe & Kirkland, 1998 ZOO-nee-SER-a-tops

From Zuni, referring to the Zuni people of New Mexico near where the specimen was found, and Greek keratops meaning 'horned face'; thus 'Zuni horned face'

93.9–89.8 million years ago Turonian, Late Cretaceous
Late Cretaceous stages

Zuniceratops is a genus of ceratopsian dinosaurs that lived during the Turonian stage of the Late Cretaceous in what is now New Mexico, United States. Only a single species is known, Zuniceratops christopheri.

Diagnosis

  1. Well-defined elongate post-orbital brow horns with flattened lateral margins
  2. Vertical-shear wear pattern on dentary teeth
  3. Single-rooted replacement teeth with one per file, lacking double-rooted dental batteries
  4. Elongate frill with squamosal forming lateral and part of distal margin of parietal fenestra
  5. Decurved ischium more curved than Centrosaurus but less than Triceratops
  6. Gracile appendicular skeleton resembling protoceratopsids
  7. Caudal extension of tooth row on maxilla beyond ascending process

Notable specimens

  • MSM P3812

    Arizona Museum of Natural History (formerly Mesa Southwest Museum) ontogeny

    The best-preserved Zuniceratops specimen, a fully adult individual represented by a right postorbital horn and associated elements; documents the mature growth stage of the taxon, in contrast to the juvenile holotype MSM P2101.
