(Medusa horned face).
Named By: Ryan, Russel, & Hartman - 2010.
Classification: Chordata, Reptilia, Dinosauria, Ornithicshia, Ceratopsia, Ceratopsidae, Centrosaurinae.
Species: M. lokii (type).
Size: Uncertain due to incomplete fossil material.
Known locations: USA, Montana - Judith River Formation.
Time period: Campanian of the Cretaceous.
Fossil representation: Two partial parietal bones (the upper part of the frill).
acquired its name from the way that the upper horns on the frill curve
which gave the vague of impression of the snakes that rise out of the
head of Medusa in Greek mythology. Medusaceratops
described as a chasmosaurine ceratopsian
dinosaur, the kind with a
very large neck frill instead of enlarged brow horns. However,
later studies, confirmed by the discovery of new fossil material
have revealed that Medusaceratops is in fact a
ceratopsian dinosaur, the kind with overly developed horns instead of
a neck frill.
Like other ceratopsian dinosaurs, Medusaceratops was a quadrupedal herbivore browsing upon low growing vegetation. Other herbivorous dinosaur around at the same time and locations as Medusaceratops would have primarily consisted of hadrosaurs, ankylosaurs and nodosaurs, while predatory threats would have principally come from tyrannosaurs and also dromaeosaurs, especially when younger.
