In 2007, however, a Russian author noticed that the name Diceratops already had been given to an insect in 1868. Two animals can’t share the same name, so he renamed the dinosaur genus Nedoceratops, a rather mean-spirited label that translates as “insufficient horned face.” A year later, a Portuguese paleontologist who hadn’t heard about the renaming proposed tweaking the original just a bit, to Diceratus. Some references now list all three monikers so people don’t get confused.
