Anyone able to ID please? Thanks

Hi, 

At Trefil quarry, Wales, I found these. They were found very close to one another. 

This site was a carboniferous coral reef.

If anyone can ID, or point me in the right direction, it'd be much appreciated.

Thanks!

I think these pieces that you've found are nautiloids. They look very similar to them and match whith the age. @Brian James Maguire could help you more i think.

Its possible that they are orthoconic nautiloid sections but the photos are a bit blurry, the first two photos look like bore holes for explosives which are man made, it is also possible that some are crinoid stems also, would need more detailed photos though

You won't be finding any baculites in the carboniferous, since they first occurred in the cretaceous. Some of these things look like wood to me. Not seeing any orthocones here.

I agree with Roger @Ludwigia. They're all plant fragments in sandstone which is probably deltaic or nearshore.

 

Corals at the locality will be in a limestone which could be above or below this, part of the typical cyclic sedimentation in this part of the Carboniferous as sea levels rhythmically shifted towards the eventual swampy Coal Measures in the upper Carboniferous. Plant material like this is not uncommon further down.

EDIT: As explained on this site, the fossiliferous limestone is overlain by a much later Pendleian and younger sandstone which is poorly fossiliferous. Occasional plant remains would be typical.

I'll go another route (agree with the post just before mine) and say these look like plant material. Especially with this detail:

Wow, thanks everyone for the replies!

I'm leaning more towards plant material, but my knowledge is very limited!

Another quick question for anyone reading; If I wanted to try to prep this smaller rock a bit, what would be the best way to go about prepping this sandstoney type of rock?

Any tips or advice is appreciated, thanks.

[Ludwigia]

What would you want to prep on that rock? If I were you, I'd leave it as is, since in my opinion, any prepping would probably rather disturb than improve it.

True, I was just wondering, as I have some experience with shale and limestone, but I don't think I've ever done anything with sandstone.
