Abstract
Speciments of the large extinct pantodont Coryphodon from the Hannold Hill Formation, Brewster County, Texas belong to single species, Coryphodon molestus. A sample of Coryphodon molestus from one locality in the Hannold Hill Formations consists of three adults and at least one juvenille. The sample aids in documenting sexual dimorphism in Coryphodon molestus and provides circumstantial evidence of gregarious behavior in that species. The presence of Coyphodon molestus in the Hannold Hill Formation indicates a late Gray Bull through Lost Cabin (Wasatchian) age. This is consistent with assignment of a late Gray Bull or Lysite age to the entire Hannold Hill vertebrate fauna.
