Abundant coprolites and possibly gut fills of holostean fishes are irregularly distributed throughout the kaolinitic clays and muds of the Whitemud Formation (late Cretaceous) of the Willows-Readlyn district, south-central Saskatchewan. The coprolites show a variety of internal and external structures including coiling, folding, and contraction marks of primary origin; secondary features, for example surface cracking, due to diagenetic replacement by siderite and pyrite, and subsequent alteration to iron oxides.
