Resumen:
Numerous eggs of capillariid nematodes have been found in coprolites from
a wide range of hosts and in raptor pellets in archaeological samples from
Patagonia. The structure and sculpture of the eggshell of these nematodes and
their biometry are commonly used for identification. The aim of this study was
to determine whether eggs of the genus Calodium with similar morphology,
found in different archaeological samples from Patagonia, belong to the same
species. For this purpose, capillariid eggs (N = 843) with thick walls and radial
striations were studied by permutational multivariate analysis of variance
(PERMANOVA). Eggs exhibiting similar shape and structure also showed
similar biometry, regardless of the zoological origin of coprolites (P = 0.84), host
diet (P ¼=0.19), character of the archaeological sites (P = 0.67) and chronology
(P = 0.66). Thus, they were attributed to the same species. We suggest that an
unidentified zoonotic species of the genus Calodium occurred in the digestive
tract of a wide range of hosts in Patagonia during the Holocene and that
both human and animal populations were exposed to this parasite during the
Holocene in the study area.
