Size (lower middle right) compared to contemporary birds, pterosaurs, and a human
Ceramornis has been placed in the family Cimolopterygidae together with Cimolopteryx and Lamarqueavis. Cimolopterygidae has sometimes been placed in the modern bird order Charadriiformes, based on quantitative analysis of its coracoid and comparison with other modern bird samples.[3][4] However, there remains some uncertainty about the taxonomic position, as there is insufficient fossil material to be assessed by wide-scale cladistic analysis.[5]
It is not certain that Charadriiformes was already distinct by the Maastrichtian.[1]
