Prenocephale skull

Juvenile Triceratops

Hell Creek Formation

In 2004, retired professor Norman Gardiner, a MRF annual volunteer since 2003, found remains from a rare juvenile Triceratops. We collected six skulls bones from the site, including the brow horn, squamosal, and dentary. The brow horn is only 30 cm long!!
