动物考古学家使用了几种方法来评估在考古遗址发现的物种对饮食的相对贡献。最常见的方法要么是基于骨骼重量是总体重的固定百分比的假设，要么是需要估计已识别的类群的“平均”身体大小。事实上，骨参数与体质量之间的关系一般是异速生长的，可以用线性回归来描述。异速生长模型的使用使原始的体重预测建立在更合理的生物学基础上，使计算“平均”体重变得不必要。讨论了异速生长的潜力，解决了反对意见，目的是鼓励其他人开发异速生长公式并在他们的研究中使用它们。
Zooarchaeologists have used several methods to assess the relative dietary contribution of species found at archaeological sites. The most common methods are either based upon the assumption that bone weight is a fixed percentage of total body weight, or require estimating an "average" body size for identified taxa. In fact, the relationship between parameters of bone and body mass is generally allometric and can be described by linear regression. Use of allometric models places original body mass predictions on a more sound biological basis and makes calculations of "average" weight unnecessary. The potential of allometry is discussed and objections addressed with the goal of encouraging others to develop allometric formulae and to use them in their research.
