Serendipaceratops (meaning "serendipitous horned face") is a genus of herbivorous ornithischian dinosaur, possibly an ankylosaur, from the early Cretaceous Period of Australia.

The find took place during the "Dinosaur Cove" project, uncovering remains at the basis of a cliff face at the shoreline; the fossil was excavated in the "Arch", a small area of sea-floor protected from the waves by a dam.

Some months later, however, on a visit to the Royal Tyrrell Museum of Palaeontology in Alberta, Canada, colleague Dale Russell pointed out its striking similarity to the ulna of Leptoceratops.

A personal friend of the couple and author of books such as 2001: A Space Odyssey and Rendezvous with Rama, Clarke first became interested in science as a child because he became fascinated by dinosaurs.

[3] However, in 2014 Rich et al. published a statistical study showing that the proportions of the holotype ulna fell within ceratopsian morphospace and found the taxon to be valid based on a unique combination of characters.
