This fossilized Triceratops was an exceptional discovery with about 80% of the skeleton presereved. Even more impressive was the 5.5 ft long, 4 ft wide skull that was nearly 95% complete. The specimen was given the nickname "Gundy" afater the Gunderson Ranch from which it was excavated. The original fossil now resides in the Gunman Prefectural Museum in Japan. Though there were once 17 named Triceratops species, there are now only two recognized: horridus with straight brow horons and smaller nasal horn, and prorsus with curved brown horns and larger nasal horn like Gundy.

These herbivores could grow up to 30 ft long and 10 ft tall, with 8 ft skulls and brown horns over 3 ft long, weighing nearly 11 tons. Their heads made up nearly one-third of their overall body length. With up to 40 tooth columns in each side of both the upper and lower jaws and up to 5 teeth in each column, a Triceratops could have nearly 800 teeth in its skull!
