In July 2016, a mummified carcass of an ancient wolf (Canis lupus) pup (specimen YG 648.1) was discovered in thawing permafrost in the Klondike goldfields, near Dawson City, Yukon, Canada (Figure 1A). The wolf pup mummy was recovered along a small tributary of Last Chance Creek during hydraulic thawing that exposed the permafrost sediment in which it was preserved. This mummified wolf pup is important to the local Tr’ondëk Hwëch’in people, who named it Zhùr, meaning ‘wolf’ in the Hän language of their community. Here, we report detailed morphometric, isotopic, and genetic analyses of Zhùr that reveal details of her appearance, evolutionary relationships to other wolves and short life-history and ecology. Zhùr is the most complete wolf mummy known. She lived approximately 57,000 years ago and died in her den during a collapse of the sediments. During her short life, she ate aquatic resources, and is related to ancient Beringian and Russian gray wolves and her clade is basal to all living gray wolves.

一具木乃伊化的更新世灰狼幼崽

2016 年 7 月，一具古狼 ( Canis lupus)的木乃伊尸体) 幼崽（标本 YG 648.1）在加拿大育空地区道森市附近的克朗代克金矿区解冻的永久冻土中被发现（图 1A）。这具幼狼木乃伊是在水力解冻过程中沿着 Last Chance Creek 的一条小支流找到的，该支流暴露了保存它的永久冻土沉积物。这只木乃伊狼崽对当地的 Tr'ondëk Hwëch'in 人很重要，他们将其命名为 Zhùr，在他们社区的汉语中意为“狼”。在这里，我们报告了 Zhùr 的详细形态测量、同位素和遗传分析，揭示了她的外表、与其他狼的进化关系以及短暂的生活史和生态学的细节。Zhùr 是已知最完整的狼木乃伊。她生活在大约 57,000 年前，并在沉积物坍塌时死在她的巢穴中。在她短暂的一生中，她吃下了水产资源，
