Cox is representing the palæo-eskimo cultural classification which is commonly divided into Pre-Dorset, transitional terminal Pre-Dorset/early Dorset, and Dorset phase. The focus area is located between Saglek Bay, Okak Bay to Nain where archaeological excavations took place both in 1969 and the early seventies. Moreover, Cox argues the possible affiliations to other complexes such as Groswater Dorset complex, Independence I/II and Saqqaq. He stands for these affiliations principally due to functional basis, particularly looking at tools collection and dwelling structures. Giving more attention to the typological links between the various Palæo-eskimo cultures with their different stages of development, Cox is not successful in making other suggestions to reasoning changes or development in material culture. For instance, Cox does not consider the possibility of environmental change to be catalyst to any cultural change or progress, but, on the other hand, he indicates that the similarities between Greenland and Port Refuge Independence I, Saqqaq and Labrador Pre-Dorset could be contemporary regional developments from a hypothetical ancestral culture rather than stages within linear evolutionary sequences. Due to the fact that the article dates back to 1978, I find the chronology satisfactory as long as one is aware of the shifting chronology due to certain factors like the development of modern technology.
