![]() ![]() Conservative estimates of fresh (wet) food intake based on mass indicate that such a size increase would require a 37–58% increase in daily food consumption. These numbers indicate that the fossil sample averaged 6–14% smaller in head and body length and 39–52% less in mass than the modern sample and that increases of 6–17% in head and body length and 65–108% in mass occurred to achieve the mean body size of the modern sample. Estimated mean length of head and body for the fossil sample is 72–79 mm, and estimated mean mass is 7.6–9.6 g. goodwini using regression models based on modern samples of shrews in the Cryptotis mexicana-group. To quantify the size differences, we derived common measures of body size for fossil C. goodwini are distinctly and consistently smaller than modern members of the species. The other two shrews, Cryptotis goodwini and Cryptotis orophila, are abundant and exhibit morphometrical variation distinguishing them from modern populations. One species, Cryptotis merriami, is relatively rare among the fossil remains. ![]() Among the taxa present are three species of small-eared shrews, genus Cryptotis. ![]() Our study of mammalian remains excavated in the 1940s from McGrew Cave, north of Copán, Honduras, yielded an assemblage of 29 taxa that probably accumulated predominantly as the result of predation by owls. ![]()
