This is a cast of a relatively small but nearly complete Pentaceratops skull found near Farmington. Note that the frill (shelf of bone projecting from the back of the skull) has two large, oval openings in it for muscle attachment.

Pentaceratops is a type of ceratopsian dinosaur long found only in New Mexico, but recently a Pentaceratops fossil was found in Colorado.
