The Museum's Triceratops at SEEC

Triceratops returns to CU campus, bigger and better than ever!

ÍÃ×ÓÏÈÉú´«Ã½ÎÄ»¯×÷Æ· 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 Colorado Museum of Natural History will remember the recent departure of the Triceratopsskull, on loan for 41 years from the Smithsonian Institution. The University of Colorado Boulder is excited to announce that, in exchange, the Smithsonian generously gifted their historic Triceratopshorridus fossil skeleton cast to the CU Museum.    

Thanks to one of CU’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 CU’s East Campus.
