Ceratosaurus is a Late Jurassic carnivorous dinosaur known from North America and perhaps Europe. It’s known for the horn on its nose and for being a distant relative of Allosaurus – also known from the Morrison Formation. Ceratosaurus tends to be rarer than Allosaurus and this is reflected in the marketplace – very few Allosaurus teeth seen for sale over the years and even fewer Ceratosaurus teeth.
