Abstract
New mammalian fossils from the Upper Cretaceous Upper Milk River Formation, Alberta [Canada], document the occurrence of a possibly new triconodontid species, and of an unnamed therian of metatherian-eutherian grade. The 2nd discovered specimen of the Upper Cretaceous triconodontid Alticonodon lindoei Fox 1969 is described, and Alticonodon is classified in a new subfamily. A new genus and species of spalacotheriid symmetrodont represented by lower molars at 5 positions and apparently not descended from the previously known spalacotheriids Spalacotherium Owen 1854 or Spalacotheroides Patterson 1955 is named and described. A lower molar is referred to the primitive therian of metatherian-eutherian grade Potamotelses aquilensis Fox 1972. The structure, size and apparent position (M.hivin.4) of the molar suggest relationship of Potamotelses with the Asiatic Upper Cretaceous Deltatheridiidae and the Lower Cretaceous Aegialodon Kermack, Lees and Mussett 1965. Kielantherium Dashzeveg 1975 is a junior synonym of Aegialodon.This publication has 5 references indexed in Scilit:
