Tidgy's Dad Posted May 22, 2018 Share Posted May 22, 2018 Interesting. A lot of the 'coprolites' from places like Madagascar look very much like this. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Innocentx Posted May 22, 2018 Author Share Posted May 22, 2018 Sideritic “coprolites” from the late Miocene of southwest Washington, the Upper Cretaceous of Saskatchewan and Madagascar, and the Permian of China have often been claimed to be pseudofossils. They are here interpreted as intestinal casts (cololites) prefossilized by bacterial activity and later transformed into siderite with no traces of original food particles left. All occurrences are found within fluvial overbank deposits that carry no other vertebrate remains. Their absence could be due to aquifer roll-fronts that destroyed phosphatic bones and teeth but favored siderite precipitation.
