It has been thought that the European and American specimens 

 were the same, but the anatomical descriptions show the following 

 differences : 



1 . American. Vertebrae 58 : cervical 7 (body of 6 first co-ossified); 



dorsal 11; posterior 40. Jackson, I. c. 166. 



2. European. Vertebrae 55 : cervical 7 (body and second and 



third co-ossified) ; dorsal 11 ; posterior 3?. Cuv. Oss.Foss.\.

This is probably a young specimen of Globiocephalus Svineval.
