MORRISON MAMMALS: PANTOTHERIA 47 



Order Marsupialia 



Suborder Polyprotodontia 



6th Family: Pantotheriidae (Trituberculata, Pantotheria)" 

 Amphitheriinae 



Amblotheriinae ( Stylacodontidae) 

 Paurodontinae 

 Diplocynodontinae 



The definitions and contents of the various families have been subject to much 

 change, but since none of these recent classifications, or of others which might be 

 quoted, was based on further original research it would serve no useful purpose to 

 follow them in more detail here. 



The molar structure of all of the genera of pantotheres is now clearly known. On 

 this and on all the other available evidence is based the following outline classification :
