Since the 1920s, two main cultural entities are distinguished in the eastern Canadian Arctic, namely Pre-Dorset and Dorset, with the latter being considered as originating from the former. This assertion has, however, been challenged for the past 30 years. To get new insights about the filiations of the Pre-Dorset and Dorset, technological and typological analyses of bone artifacts were performed on collections from five type sites located in the northern Foxe Basin and on the southern shore of the Hudson Strait. Jørgen Meldgaard’s excavations in the Igloolik area (1950s–1960s) have been revisited, as well as those of William E. Taylor Jr. (1958) and the Avataq Cultural Institute (2001–2006) at the Tayara site. New elements of change and continuity through time were observed that permit refinement of the definitions of the Late Pre-Dorset, Early Dorset, and Middle Dorset phases. In the studied areas, clear filiations are seen from Pre-Dorset to Dorset that probably arose in situ. Based on technological and typological criteria, a reassessed relative chronology is proposed for the eastern Canadian Arctic.

以骨骼技术和类型学为重点的加拿大东部北极地区从多塞特郡到多塞特郡的文化连续性

自1920年代以来，加拿大东部北极地区有两个主要的文化实体，即多塞特郡和多塞特郡，后者被认为是前者的起源。但是，在过去的30年中，这一主张一直受到挑战。为了获得有关Pre-Dorset和Dorset的变迁的新见解，对位于福克斯盆地北部和哈德逊海峡南岸的五个类型遗址的骨制品进行了技术和类型学分析。约恩·梅尔德高德（JørgenMeldgaard）在Igloolik地区（1950年代至1960年代）的发掘活动以及塔亚拉（Tayara）遗址的小威廉·泰勒（William E. Taylor Jr.）（1958年）和阿瓦塔克文化研究所（2001-2006年）的发掘活动都得到了重新研究。观察到了随着时间变化和连续性的新元素，这些元素可以完善晚期多塞特集的定义，多塞特郡早期和中期。在所研究的地区，从多塞特郡前到多塞特郡均可见明显的f变，可能是原地出现的。根据技术和类型学标准，提出了对加拿大东部北极地区的重新评估的相对年表。
