Amateur fossil finds

[AJPW]

Hey,

 

I’ve finally spent some time on the Jurassic Coast the last few days around Portland, Lulworth Cove and Lyme Regis / Charmouth beach and thought I would share what I’ve found.

 

Not loads but my own first fossil which I’m pretty proud of even if it’s tiny lol! It’s part of a infant ichthyosaur neck vertebrae if I’m correct.

 

Also some photos of Ammonite imprints on some big rocks and a rock I found and broke open with an ammonite imprint and possible tooth imbedded in it? Also random photos of not sure what lol

 

let me know please what you think.

Numbering the pictures would be helpful here. 

But, yes, the first two are of an icthyosaur vertebra. 

Next are pieces of belemnite.

Next one, I can't see well enough to tell. 

Then it's an ammonite.

Then, a pyrite nodule.

Then, the same one I can't tell what it is, again.

Then, bits of ammonite with a nodule.

And finally, part of a calcite vein. 

I think.

Nice finds! #1 is an icthyosaur vertebra  

 

@Tidgy's Dad beat me to it haha

Hi,

 

I found the fifth photo in mud and thought it was a peice of metal then maybe an ammonite. Please look at more photos of it I’m thinking it’s a ammonite that been preserved in fools gold?

 

one side has been crushed and the other side is partially visible?

Last piece looks like a concretion, not a fossil.

@Tidgy's Dad, how do you Distinguish ichthio from shark vertebrae?

[AJPW]

I thought that but you can see ridges in a pattern like an ammonite which makes me think that the pyrite has formed over an ammonite?

But it is nor spiraled like a ammonite would be.

I don't think shark verts are found at Lyme Regis for one thing. 

When I'm holding one of each, the main difference is the weight, the cartilage is usually much, much lighter of course. 

But i'm not any sort of vertebrate expert, I just know from experience the fossils of Southern England. 

You can find shark fin spines (eg Hybodus) but i guess preservation wasn't suitable for cartilage ? 

[AJPW]

Yeah but parts of it look spiralled in the general shape thinking it’s been poorly preserved or damaged?

 

Thanks for all the replys and feedback by the way :)! Hoping to go back during the winter maybe next year to get more fossils!

Nope.

I may be totally wrong but this is how I was picturing it. Also it was found in the area where they find pyrite ammonites which is why I’m thinking it is

Alas, I wish it were.  The inconsistency of the spiral near the centre in terms of shape (it's a bit too bumpy) and lack of gradual resolution as you proceed inward probably mitigates against this as being an ammo. 

 

Still, it may be worth keeping for the suggestive shape alone.
