Castles and Coprolites

I am so happy that I've actually managed to get some microscope work done over the past couple of weeks. It feels like forever since I had the time to do any lab work, or spend time looking down the microscope. Even on my research leave, I have been so busy writing papers and grant applications that microscope time has taken a back seat. I am currently working on the 30 or so slides we collected as part of a NERC project at Paisley Caves in Oregon . This week I have been focusing on characterising the different types of faeces that are found in the sediments. There are lots of different types - rat and bat dung , ovicaprid type pellets, and of most interest of course, the potential human coprolites. I say potential, as we can't know for sure if they are human without conducting additional biomolecular analysis , but the pictures below show a likely human candidate. In any case we can say that it is omnivore coprolite, containing both digested bone fragments and plant tissues. T...
