Getting the Dirt On Ancient Life With Coprolites

the_newsbeagle writes "Paleoscatologist Karen Chin knows you can learn a lot about ancient ecosystems by studying coprolites — fossilized feces. She has studied dino droppings from herbivores, and identified the types of plants those dinosaurs ate. She has identified T. rex turds, and found evidence that prehistoric dung beetles made use of those king-sized dino patties. This profile of Chin goes through her greatest hits, then focuses on her latest work, which sheds light on the reemergence of life after the K-Pg extinction event that brought down the dinosaurs... but left some surprising creatures unscathed."

      Actually a lot of the extracted solids are shipped off to landfills. In most sewage treatment systems the first step is a settling tank that allows the heavier solids (sludge) to sink to the bottom where a screw then lifts them out. The solids (toilet paper, feces etc.) is then dewatered and shipped to landfills. I am familiar with the NYC DEP system as a family friend works for them. Some plants do not dewater their own solids and have to ship them by a DEP barge to other plants which do. One such plant is the Rockaway plant.

    A good deal of the steel we use in our modern civilization comes from ore produced by a singular event of some 2 billion years ago. The amount of oxygen in the atmosphere and ocean had increased to a level that all the Iron that had been in solution suddenly rusted out of sea water and settled out eventually becoming the worldwide distribution of ironstone deposits from that age.

    In a few million years, our age will be marked by regions of very rusty deposits scattered about the continents. If you have seen the series on Discovery about what happens to human artifacts after Mankind is not maintaining them, it seems that steel structures are among the least able to survive for very long, at least in terms of geologic time. Some metal artifacts might survive by luck, but most of it will return to the rust that made the ironstones in the first place, but it won't be a orderly deposit. It will be localized where our population centers were, but the striking thing will be the unnatural concentration of Iron with anomalous associations of other metals not found together in natural deposits.
