描述了产自美国北卡罗来纳州上三叠统横齿兽类北方阔齿兽新材料的牙齿。基于牙齿的特征,尤其是犬后齿的形态,这些标本被暂归入杰斐逊北方阔齿兽Boreogomphodon jeffersoni;不过它们的下阔齿型犬后齿前横脊一般有两个而不是3个齿尖。根据牙齿大小、直接替换情况,推测阔齿型齿从后部萌发,从前部脱落。这个类群仅有一代阔齿型犬后齿;至少有一代,可能是两代裂齿型犬后齿。
Describes the teeth of a new material from the north of the Upper Triassic mammals of North Carolina, North Carolina, North Carolina, USA. These specimens are tentatively assigned to Boreogomphodon jeffersoni in the northern jeopardy of Jefferson, based on the characteristics of the teeth, especially the canine posterior teeth, but their lower wide anterior canine posterior transverse ridge generally has two rather than three tips . According to the size of the teeth, direct replacement of the situation, presumably wide teeth tooth germination from the back, from the front off. This group has only one generation of broad-leaved canine posterior teeth; at least one generation, probably two generations of split-dentate canine teeth.
