根据两个加州海狮（Zalophus californianus）的平均肉重，提出了一个实用指数。相对于最近推导的phocid密封指数，otariid密封指数有更高的值为颈椎和前肢元素，和较低的值为胸椎和腰椎和骨盆。应用到考古otariid组合从密封岩石网站在俄勒冈州海岸，并从点Mugu网站在加州海岸，证明了有用的otariid密封指数，而在同一时间强调的phocid密封指数不适用于这样的组合。
A utility index for otariid seals, based on the average flesh weight per skeletal portion of two California sea lions (Zalophus californianus), is presented. Relative to the recently derived phocid seal index, the otariid seal index has much higher values for the cervical vertebrae and forelimb elements, and lower values for the thoracic and lumbar vertebrae and pelves. Application to the archaeological otariid assemblages from the Seal Rock site on the Oregon coast, and from the Point Mugu site on the California coast, demonstrates the usefulness of the otariid seal index, while at the same time underscoring the inapplicability of the phocid seal index to such assemblages.
