Medusaceratops acquired its name from the way that the upper horns curve downwards, which gave the vague of impression of the snakes that rise out of the head of Medusa in Greek mythology. Unfortunately little more is known other than it was a chasmosaurine ceratopsian, which means that it may have displayed characteristic features of the group such as long frill and possibly smaller horns that the centrosaurine group.
