The great 2020 saurischian streak has broken! Finally we get a new bird-hipped dinosaur, and it’s a ceratopsian. I’m including this new horned dinosaur, Stellasaurus, along with another recently discovered and also fragmentary new taxon from Mexico: Paraxenisaurus. Without further fuss and ado . . . .
