由于缺乏哺乳动物牙齿萌出和磨损等技术，确定鸟类停止生长后的遗骸年龄具有挑战性。没有这些技术，就很难重建狩猎策略、畜牧制度和更广泛的人与动物关系。本文提出了一种新的方法，从收集（n= 71）已知年龄的家禽标本（原鸡dominusL. 1758年），用于基于跗跖骨刺的融合和大小来评估年龄。使用这种方法，我们重建了从铁器时代到英国近代早期的家禽人口统计数据，揭示了人类家禽关系的变化动态。我们强调了公鸡在其早期历史中经常达到的高龄，以及它们的预期寿命随后如何下降。
Determining the age of bird remains after the cessation of growth is challenging due to the absence of techniques such as tooth eruption and wear available for mammals. Without these techniques, it is difficult to reconstruct hunting strategies, husbandry regimes, and wider human–animal relationships. This paper presents a new method, developed from a collection (n= 71) of known‐age specimens of domestic fowl (Gallus gallus domesticusL. 1758), for assessing age based on the fusion and size of the tarsometatarsal spur. Using this method, we reconstruct the demographics of domestic fowl from Iron Age to Early Modern sites in Britain to reveal the changing dynamics of human–domestic fowl relationships. We highlight the advanced age that cockerels often attained in their early history and how their life expectancies have subsequently declined.
