Triceratops regularly reached up to 30 feet tall and weighed over 11,000 pounds, though many specimens are estimated to have weighed more than 16,000 pounds. For comparison, adult African elephants stand up to 13 feet tall and weigh around 13,000 to 20,000 pounds.
There are sixteen recognized species in the genus triceratops, as of 2015. Not all species of triceratops lived at the same time. Their name derives from their characteristic three horns on top of their large skull, which also had a bony frill protecting the neck. They were vegetarians and are suspected to have fed on shrubs and other coarse plant life.
