Yorkshire Fossil Finds: Ammonites, Curved (Stone?) Plate, and 'Olympus Mons'
JamieC7696 posted a topic in Fossil ID
These are some finds of mine made on the Yorkshire coastline... It would be truly spectacular to have very specific identifications for all of them - and even the ones that 'just' turn out to be regular stones and rocks! Regarding most, I think they're quite fragmentary... Key: 1-9 = Everything up to the first Ammonite 10-18 = Ammonite material? 19-26 = Alternative shells 27-29 = 'Olympus Mons'/multilayered rocks 30-35 = Other -

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 given is for the inclusions, not the coprolite. Aside from the hooks, it is hard to definitively identify the inclusions without damage to the coprolite. The following is a list of inclusions: 241 hooks of various sizes that are at least 75% intact. 200+ plate-like fragments of various sizes (likely similar to the surface nacre). 19 ellipsoidal structures, possibly forams or parasite eggs. 2 unidentified long, straight conical structures joined at wide end (A) 1 long rod-like structure with a bulbous end (B) 1 unidentified mass that looks like it was the attachment point for 5 rod-like structures (C) 1 1ong cylindrical (rod) structure that tapers in the center. The center density is much lower than the outer shell (D) 1 irregular structure that looks I originally thought might be an ink sack or buccal mass, but the size is wrong. Experta think it is more likely foraminifera (E) 1 irregular structure, possibly a statolith (F) Acknowledgements: Thank you to Neale Monks and Christian Klug for providing input.
