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

What do you think these are? Sorry, this is the only picture, and there is literally 0 information, so just your best thoughts from what you see here. I'll update any info if I can.

Hi, I've only recently been bitten by the fossil bug, especially trilobites & ammonites. I was driven to seek out those more knowledgeable that I by one question: - I recently bought a reprint of Joachim Barrande's "Systeme Silurien du Centre de la Boheme, Vol 1: Trilobite, Crustaces Divers Et Poissons". I was disappointed to find that although the text is all good, the plates of diagrams that are so famous are not reproduced in this volume, depite being referenced frequently in the text. Does anyone know where I can get hold of copies of these plates? Are they in another of his works, and if so, which one? Any help much appreciated. Thanks, Simon.

I'd like to go out to look for some decent fern fossils before the end of September. Can anyone suggest a spot or mind if I tag along with them?

Hi all! Under the presumption these are echinoderm I've been searching for anatomical features, particularly disarticulated crinoid and archaeocidaris of which both are plentiful in the matrix. In my searching I've been unable to find anything that even remotely resembles these pieces. Any input is much appreciated. Plattsburg fm. - Hickory Creek sh. I attached a group photo of some of them I found, followed by 4 select specimens showing each side front and back. For scale, field of view is ~1cm. Group shot Front Back Front Back Front Back Front Back Thank you all!

Anyone have any information on tectonic activity during the Cambrian Period? I am writing a report on tectonic activity on Earth and am going to use the Cambrian to explain the location of the Burgess Shale and Chengjiang formations. So far I have a good idea of what I am doing, just wanted some input from others. I'll reference anyone that responds. Thanks.

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.

I have always loved the multi fish murals but I have no access to fish fossils here. So I'm going to attempt the same with my trilobites. So far it looks a small puzzle I hope to grow on. Has anyone tried this before? What are the protocols? I was planing to keep it to Penn Dixie stuff.
