Protoceratops was a small ceratopsian without big horns — just a small bony frill behind the skull and a parrot-like beak. Hundreds of skeletons have been found in Mongolia, including the famous ‘Fighting Dinosaurs’ fossil where a Protoceratops is locked in combat with a Velociraptor, both buried by a collapsing sand dune.

What we know

  • Small bony frill, parrot beak, no horns.
  • Found in Mongolia in vast numbers — hundreds of skeletons known.
  • The 'Fighting Dinosaurs' specimen preserves combat with a Velociraptor.
  • Eggs and nests found nearby, mistakenly attributed to Oviraptor in 1924.

What we guess

  • Whether the small frill was for defense, display, or muscle attachment for chewing.
  • Whether the legend of the griffin came from ancient peoples finding Protoceratops bones near gold deposits.
  • Whether the eggs Roy Chapman Andrews collected in the 1920s belonged to Protoceratops or Oviraptor (later DNA-style analyses say both species used the area).
