Lalibela
Good evening!

I’ve been on holidays on North Spain recently and I found this stone in the top of a mountain, surrounded by plenty of marine fossils, as you can see on the last couple of pictures.

Do you have any idea of what this could be?

Many thanks.

Hello, I think this is just a pebble, but it has been run over with a trillo; a devise with flint implements to egalize the field...was it found on a farmers field?

greets, Bert
the search is as valuable as the finds...

Hi Bert,

Thank you for your answer.

No! It was found in the top of a mountain... It was just as shown on this picture... Click image for larger version - Name: 4824BAAF-2C4E-4C6E-B3AE-DC7FA924DDF4.jpeg, Views: 15, Size: 843.63 KB

I agree with Bert, a pebble with some sort of erosion grooves

Thank you Buzz2. 

Do you have any idea of I could clean the last two?

I would try soaking in white vinegar for a few minutes and then rinsing well. It sometimes just cleans them up a little and makes the fossils pop. They should fizz in the vinegar...keep checking them...don't leave them too long. They should clean up nicely. Good luck.

Hi Lalibela, This 2nd last photo would benefit from cleaning, but I don't know the rocks from the area, so it will be 'hit and miss'! Check to see if the acid will dissolve the matrix rock (test on an inconspicuous area first , (you will see 'fizzing if it works)  but remember it will dissolve the fossils it contains as well.  It would be better to have it air abraded by someone who has the equipment but this may cost you! The 3rd option would be to grind it flat to the depth of the crinoids and then polish using finer grades of 'wet and dry paper' and then polish it.

Colin, Anne, Thank you for your explanations. I‘ll give it a try in December when I get back to Spain and I’ll post some pictures! (Hopefully I’ll manage to do something with your advise!)

I wouldnt do too much cleaning, just give it a gentle wash.

Thank you Gary. I already tried in another piece from the same area and unfortunately it didn’t make much difference... the greenish areas remained the same...
