Hi people, I have a query regarding the contents of some siderite nodules from a Duckmantian fossil forest site in N Wales for my PhD project. I had thin sections made of parts of several nodules and they all seem to have an abundance of 'faecal pellets'; rounded, often curved (banana-ish) shaped, mostly stratified pellets. These pellets have been replaced by siderite (FeCO3) and sometimes include pyrite and seem to have been the locus for early sulphate reduction by bacteria before conditions arose for the siderite precipitation. I've attached SEM images of the thin sections showing some of these pellets. We have only found a couple of fragments of crustaceans (Euproops I believe) and the host sediments were fine sands and silts. All the images show individual pellets with scale bars but "pellet5" is a zoomed out image showing the abundance of the pellets. They are all replaced by an Fe-rich siderite and are all quartz free. "pellet6" is different with a mottled texture and some potential apatite mixed in. Let me know if anyone has seen similar textures before and/or what could have made them! The palaeoenvironment was purely freshwater with meandering river systems, with a dynamic lycopod dominated fossil forest ecosystem. pellet3.pdf pellet2.pdf pellet1.pdf pellet5.pdf pellet4.pdf

Goodmorning, last month I went to Solnhofen for my last fossil trip of the year in Germany. I found a lot of fossils (ammonites, coprolites, fish, worms...) and now I'm preparing the specimens. I have basic tools, a Dremel 290, needles, awls. I prepare all of these fossils with succes, but a big coprolite is still covered buy a tiny layer of matrix, that I can't remove with my actual tools. It's possible to effectively remove the matrix left with acid? Tomorrow I will post a photo of the fossil. Thanks.

It's hard to capture the beauty of this thing in pictures. Could it be an egg? Just a fascinating coprolite that shows its contents?

This thing looks pretty bizarre. It's very dense, and has no tongue-sticking, so I think it's just a strange looking, bad-tasting rock. Every time my son or I tried to see if there was any tongue-sticking on the small black section, we were running to the kitchen to wash our mouths out--very sour, metallic taste. I'm worried we tasted dino poop. Or is this just some rock that should have stayed in the ground?
