Yorkshire Fossil Finds: Ammonites, Curved (Stone?) Plate, and 'Olympus Mons'
JamieC7696 posted a topic in Fossil IDThese 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...

What kind of arthropods are these?
Still_human posted a topic in Fossil IDWhat 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.

Upper Pennsylvanian Micro (2)
Bullsnake posted a topic in Micro-paleontologyHi 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.

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
Cambrian Tectonic Plates
opabinia posted a topic in Questions & AnswersAnyone 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.
Coprolite with cephalopod inclusions
GeschWhat posted a fossil in IchnofossilsThis 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
Mosaic Murals of Trilobites
ischua posted a topic in Member CollectionsI 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.
