However... what if the dicynodont maxilla is actually a ceratopsian
premaxilla? Even without *Serendipaceratops*, this would be less bizarre
than a K dicynodont.
_Serenipaceratops arthurcclarkei_ is known from an ulna that looks a lot
like the ulna of _Leptoceratops_ (which is why the Riches regard the ulna as
protoceratopsian). The ulna of _Serendipaceratops_ has slightly different
proportions to the ulna of _Leptoceratops_ (which is why the Riches accord
the ulna its own genus). However, as the Riches note, the ulna also bears
an overall resemblence to the ulnae of certain theropods. Thus, although
the ulna is PROBABLY from a ceratopsian, I can see a few folks keeping an
open mind over whether we yet have "proof" of Aussie ceratopsians.
BTW, on a dinosaur trivia note: The name _Serendipaceratops_ not only
references the serendipitous discovery of the ulna, but also "Sarandib", an
old name for Sri Lanka, the current residence of Arthur C. Clarke (honored
in the species name).
