SUPPOSED EUROPEAN REPRESENTATIVES OF THE CERATOPSIA. 



All of the above enumerated genera and species are from the Cretaceous deposits of the 

 United States, and all genera and species are included that have at any time been referred 

 by any authority to the Ceratopsida?, although some of these, as will be shown later, pertain to 

 families quite distinct from the Ceratopsidse, belonging even to different suborders. 



In addition to the above mentioned American genera and species several European forms 

 have at various times and by various authorities been regarded as pertaining to the Ceratopsia. 

 These are:

The above mentioned genera and species are from the Gosau beds (Upper Cretaceous) of 

 Austria. In addition to these, various other dinosaurian remains from Europe and elsewhere 

 have at different times been described by various authors as showing characters indicating
