Crateropteryx was named by the paleontologist Harry Seeley in 1900.1

Its full scientific name is Crateropteryx colei.1

Crateropteryx was a ground-dwelling bird that laid eggs.1

發現: Crateropteryx was named by Harry Seeley in 1900 based on a single humerus fossil. The bone was collected from the Stonesfield Slate quarries in England, possibly as early as the 1790s.1 2
仍有爭議: Scientists are not sure exactly how big Crateropteryx was, because only one arm bone has been found.1
