A Triceratops at CU—A Piece of Colorado's Past
On Jan. 16, the day students returned from winter break, the CU Museum of Natural History unveiled a full-scale Triceratops skeleton in the lobby of the Sustainability, Energy and Environment Community (SEEC) building on Ҵýƽ East Campus. The dinosaur is a skeletal reconstruction cast from the bones of several Triceratops that once roamed the West. The free exhibit is open to the public.
The Smithsonian Museum delivered the disassembled skeleton via truck to Boulder in 2022. A crew put it back together off-site before bringing it to its current SEEC location.
“Everybody knows about Triceratops,” said Karen Chin, geological sciences professor and the museum’s paleontology curator. “But it’s not common in museums to see the whole animal. To see the scale of this dinosaur, and such a weird dinosaur, is very exciting.”
