Stellasaurus is a genus of centrosaurine ceratopsian
lived in North America during the late Cretaceous. Although little
fossil material exists of Stellasaurus at the time
of writing, the
dinosaur has been reconstructing as having two large upwards pointing
spikes rising from the back of the neck frill. Two smaller spikes
rose up at slight angles outwards either side of the two central
spikes. These created a star shape which was the inspiration of the
name Stellasaurus. Stellasaurus
is also a homage to the song
‘Starman’ by David Bowie.
