Journal Article A new genus and species of cynodont from the Upper Triassic Fleming Fjord Formation of East Greenland possesses double-rooted postcanine teeth and a nonalternate pattern of tooth replacement. The specimen represents an addition to the known diversity of Early Mesozoic taxa with multi-rooted dentitions (tritylodontids, Sinoconodon sp., haramiyids, morganucodontids, Meurthodon gallicus), and casts doubt on traditional interpretations of the interdependency of reduced tooth replacement patterns and teeth with multiple roots.
