The Museum's Triceratops at SEEC

Triceratops returns to ÃÛÌÇÖ±²¥ campus, bigger and better than ever!

ÃÛÌÇÖ±²¥ Boulder is now home to a full-scale Triceratopsskeleton cast! This replica of the first mounted Triceratopsin the world is based on bones from 10 different specimens of Triceratops horridus, collected in Wyoming in the early 1890s.  

Dedicated visitors of the University of ÃÛÌÇÖ±²¥ Museum of Natural History will remember the recent departure of the Triceratopsskull, on loan for 41 years from the Smithsonian Institution. The University of ÃÛÌÇÖ±²¥ Boulder is excited to announce that, in exchange, the Smithsonian generously gifted their historic Triceratopshorridus fossil skeleton cast to the ÃÛÌÇÖ±²¥ Museum.    

Thanks to one of ÃÛÌÇÖ±²¥â€™s paleontologists, Dr. Jaelyn Eberle, and a range of staff across campus puzzling on its placement, the Triceratopsskeleton is now on display in the atrium entryway of the building, located on ÃÛÌÇÖ±²¥â€™s East Campus.
