Triceratops may be the best-known horned dinosaur, but a new exhibit arriving at the Peterborough Museum & Archives this fall shows there was much more to the prehistoric family.
“Horned Dinosaurs: More Than Triceratops” opens Saturday (November 7) and runs until March 21 at the museum at 300 Hunter Street East, at the top of Armour Hill in Peterborough’s East City.
Developed by Research Casting International, the exhibit features a dinosaur skeleton, a variety of skulls, and interpretive displays exploring ceratopsians — plant-eating dinosaurs distinguished by their beaks, horns, and prominent bony frills.
“We’re excited to bring another engaging dinosaur exhibit to our community,” said Peterborough Museum & Archives director Susan Neale in a media release. “Horned Dinosaurs: More Than Triceratops invites visitors to get curious, ask questions, and discover what these remarkable creatures can tell us about life millions of years ago.”
The exhibit marks a return to the Peterborough museum for Research Casting International. From October 2025 to March 2026, the museum hosted the Trenton-based company’s “The Carnivorous Dinosaurs: Theropods” exhibit.
This time, the focus shifts from carnivores to herbivores and how their distinctive horns and frills varied among species, how the animals evolved and interacted with their environments, and what scientists have learned from the fossil record.
Ceratopsians first appeared in Asia during the Late Jurassic period around 150 million years ago. Early species were comparatively small, while later forms developed the characteristic frills associated with the group.
Around 100 million years ago, some ceratopsians migrated from Asia to North America, where the large-bodied Ceratopsidae family eventually evolved. Those later dinosaurs walked on four legs and had large heads, prominent frills, and strong, short necks.
All ceratopsians had beaks that helped them cut woody plant material before processing it through their jaws and digestive systems.
Research Casting International has worked with paleontological specimens and museum exhibits for more than 35 years, specializing in fossil conservation and restoration, casting, specimen mounting, and exhibit fabrication.
Through its Exploration Exhibits division, the company produces natural history exhibits for museums and other venues.
“Horned Dinosaurs: More Than Triceratops” features a medium-sized skeletal display, skull specimens, and interpretive panels.
Peterborough Museum & Archives will extend its hours for the opening weekend of Horned Dinosaurs, operating from 10 a.m. to 5 p.m. on Saturday, November 7 and Sunday, November 8.
Regular museum hours are 9 a.m. to 5 p.m. Monday through Friday and noon to 5 p.m. on Saturdays, Sundays, and most holidays. The museum will be open regular hours on Remembrance Day (Wednesday, November 11).
Admission to the museum is by donation, with $20 suggested for a family or small group.
