The genus was first discovered in 1887, and subsequently classified in 1888 by paleontologist Othniel Marsh (who'd initially believed the fossil to be a prehistoric bison).
Triceratops in "The Green Buffalo"Edit
In an 1890 expedition to Wyoming, John Bell Hatcher discovered fossils of what he thought were Triceratops. When he telegraphed his employer, Othniel Marsh, Marsh quickly realized that Hatcher's new fossils were not Triceratops, but a related genus which became known as Torosaurus.
Triceratops in "Running of the Bulls"Edit
The running of the bulls was an annual festival in the Astilian city of Amblona. A herd of the large animals would be released in the street, while people ran in front or along side them. Naturally, given their tremendous size and prominent horns, people were seriously injured or killed during this event.
The running itself was connected to Astilia's worship of the god Thimras, who had the head of a bull and the body of a person. A priest and his acolytes would bless the bulls the day before the run. On the day of the run, they would cover the people running from snout to tail in white paint, to show Thimras their purity.
After the run, bullfighters fought some bulls to the death.
