So, super early on Friday morning I drove down to Charmouth from Coventry for three days of solo hunting.

I've not done it before and I loved it. Turning up at the beach as high-tide started to ebb, picking my way along the first few slips, dodging waves. I must have looked the part - all-weather gear, rock hammer, covered in clay - as a number of people seemed to think I looked like I knew what I was talking about as I kept getting stopped for fossilising tips! The Storm Jorge, while it largely missed Charmouth, did mean some strong storm swells, and lots of significant cliff falls. Anyway…

Here follows a general grab-bag of finds followed by a few query points:

  1. IMG_6352.jpg 
  2. IMG_6353.jpg  IMG_6354.jpg 
  3. IMG_6355.jpg  IMG_6357.jpg 
  4. IMG_6358.jpg  IMG_6359.jpg  IMG_6360.jpg  IMG_6361.jpg  IMG_6362.jpg 
  5. Here's the first interesting one. I'm confident it's bone - though I put it in my find bag fully expecting it to be a nodule when I cleaned the clay away. There's a couple of things it could be, but it looks like it might be a Plesiosaur limb bone? It was found in a clay slip toward the west-end of the east "fossil" beach.

  6. Unsure about this one. I think it's probably a pyrite nodule, but wanted a second opinion…

  7. No idea what's going on here, bivalve section? Mammal tooth? …eh?

  8. And this is anyone's guess. I assumed it was a pyrite nodule, until I realised how symmetrical it was.

5. Ichthyosaur femur I think 
7. could we have more pictures please? It’s very interesting. It looks fossilised but mammal teeth are extremely rare at Charmouth so this ones got me stumped!
8. I think I can see part of a pyritise crinoid protruding from the back

Great finds and I love the echioceras and the eoderoceras pyrite ammonites! Thanks for sharing!

5. I've looked that up, Ichthyosaur femurs look triangular in section, and the ends are pinched. The more I research, the more I'm leaning towards Plesiosaur phalanges »  https://jurassiccoast.org/what-is-the-jurassic-coast/all-about-fossils/fossil-finder/fossil-finder-database/865-plesiosaur-phalanges/
7. I'll see what I can do tomorrow 👍
8. I believe you're right. I think that's stuck on though, rather than part of the main structure.

…and sharing's a pleasure 😁

Ooow! Scelidosaurus phalanges?

Scelidosaurus bones are extremely rare and category 1 fossils. Only a few if any are found each year. I think the ends of your are more pinched dinosaur bones and the anatomy of a phalanx doesn’t fit. However, I think you should get an expert to confirm this.

#5 is a plesiosaur paddle digit.

#6 looks like a very worn ichty vert
#7 is a modern small herbivore mammal tooth not a fossil
#8 completely pyritised echyoceras (or something similar)

Hey, thanks!

#6 is appears to be pyritised and is surprisingly heavy, so I was assuming the probability of it being bone was very low.

#7 yes, I was coming to that conclusion 👍

#8 interesting. There's trace pyrite crystals on the surface, but it superficially appears to be mudstone with no evidence of the external structures you'd expect to see somewhere. That said, it's got exactly the kind of profile you'd expect to find in a largely pancaked ammonite with the preserved body chamber.

I don't have access to the kind of tools that would let me strip away the matrix. Any suggestions on prepping?

I’m not really seeing an ammonite in no.8. I see a nodule with pyritise crinoid pieces on it. Have you got access to a hammer a pin and a small chisel? Those could be used in prep.

Phalanx of an indeterminate plesiosaurian, would be my view of your bone find. Makes a nice change from the usual small ichthyosaur verts found here.
