This was found in Ireland county wicklow. The rock is fairly soft.
Is it a fossil and if so how old is it roughly?
Thank you in advance
My initial reaction is belemnite or crinoid, but we could really do with seeing things in cross section. Can you see what the fossils look like on the sides of your specimen? If they do not show up there, you try breaking the specimen carefully, perhaps near an edge. Either way, the fossils may appear almost identical to the host rock, so near-impossible to see - but it really would help to try...
Interesting - I see cross-sectional shapes that are triangular, square, rhombic, and irregular.
I see no rings (belemnites can show rings depending on where they are interescted),
and if they were crinoid, I would expect them to be near-circular, and we should have seen segmentation in the long section.
I think the cross-sectional shape and overall elongation rules out fish scales.
Hmmm... Part of me wonders about metamorphic minerals; also, echinoderm spines (can't remember having seen them with faceted sides). I'm open to other suggestions...
Is there any chance of you cutting a cross-section of one/some, wetting/varnishing it, and using a hand lens to look for internal structure and/or posting a close-up photo?
I'm about to ask some newbie questions, sorry :)
I'm 17 and a few days ago I found my first fossils !
They were crinoids and one of those fenestrate Bryozoa things and yesterday this weird thing.
Just wondering what tools should I use to cut these? And how should it be done?
Thanks a lot for all your help.
One of the hardest things when answering questions here is knowing the level to pitch them at - through not knowing the inquirer. But we usually get there, perhaps making a few imperfect assumptions along the way. So thanks for clueing me in about yourself a little.
Ideally, you need a lab, but even a well equipped lab will be missing some expensive apparatus. Almost all of us have to make-do. That also forces us to be inventive and think laterally. You have not been stretched yet, but you have made a promising start. So far in your geological career, you have:
Curiosity, ability to research, and collaboration are vital assets for a scientist.
In your postings here, you also demonstrate: good writing skills (use of comma and hyphen, capitalization of initial of Bryozoa, etc.) and consideration for others ('Thank you in advance'). Your writing indirectly informs your readers about yourself and in so doing engenders effective collaboration. All good stuff.
Now, in the current instance:
