Skeleton of extinct North American sea mink (Mustela macrodon)
Mustela macrodon (extinct sea mink) is known only from prehistoric and historic Native American shell middens dating less than 5100 years old along coastal islands of the Gulf of Maine, northeastern North America. The species is distinct from all
known extant subspecies of M. vison (Amerikan mink) but still belongs to the North American subgenus Vison. Here the AA. describe the quantitative and morphological characters observed on the skull, mandible, humerus, radius, femur, and tibia
