Coprolites were collected with the aid of a rectosigmoidoscope from a naturally mummified body of a child. The body dates from 3.490 +/- 120 to 430 +/- 70 BP and was found in the State of Minas Gerais, Brazil. The coprolites were rehydrated with a trisodium phosphate solution and concentrated by the spontaneous sedimentation method. Microscopical examination showed eggs the same shape and size as those of Trichuris trichiura and of an ancylostomid.
借助乙状结肠镜从一具自然木乃伊化的儿童尸体中收集了粪化石。该尸体年代测定为距今3490±120年至430±70年，在巴西米纳斯吉拉斯州被发现。粪化石用磷酸三钠溶液复水，并通过自然沉降法浓缩。显微镜检查显示虫卵的形状和大小与鞭虫及钩虫的虫卵相同。
