In short, I'm trying to figure out exactly what was on the menu: fish or cephalopods. While sorting through some Oxford Clay fish coprolites, I came across this specimen. It was part of a batch purchased years ago. I must have just assumed the inclusions were fish vertebrae, but now I'm not too sure. I know some vertebrae from some fish fry can be hollow, but the texture/material of these inclusions look very different from anything I've seen (including vertebrae in Oxford Clay coprolites). Because of the color and layers, I'm thinking these may be chitinous. That said, I haven't s

As I was putting together labels with photos containing microscopic images of inclusions in coprolites, I came across something that I may have misidentified as a fish tail and vertebrae in a very small coprolite. After looking at it again, the tail looks more like a shrimp or crawfish tail than that of a fish. What I thought were fish vertebrae, look more like crustacean arm joints/elements. Can anyone please confirm this for me? Thanks a bunch! Formation: Oxford Clay (Jurassic - Callovian) Location: Orton Pit, near Peterborough, Cambridgeshire, England

This coprolite is from a marine creature that swam in the Jurassic seas that once covered this parts of England. The dark inclusions that can be seen on the surface are Onychites (cephalopod hooks). In April 2016, the University of Minnesota X-ray Computed Tomography Lab scanned the specimen using a X5000 high resolution microCT system with a twin head 225 kV x-ray source and a Dexela area detector (3073 x 3889 pixels). Many of the images shown here are of individual 3D elements/features within the coprolite that were separated/isolated using Blob3D. The taxonomic classification gi

CT Imagery of Coprolite with Cephalopod Hook Inclusions

From the album: Coprolites
This is a brief video showing inclusion contained with in a Jurassic marine coprolite thanks to the magic of X-ray computed tomography (aka Micro CT Scan). The coprolite is from the Oxford Clay Formation, Orton Pit, Peterborough, Cambridgeshire, England. Imagery was provided by the University of Minnesota X-ray Computed Tomography Lab. -
I had this little coprolite from the Oxford Clay, Orton Pit, Peterborough, Cambridgeshire, England, scanned by the University of Minnesota X-ray Tomography Lab. Some cephalopod hooks were visible on the surface under magnification. I was amazed by the number of hooks that were revealed by the micro CT scan. Here is what was visible on the surface:
