Possible seeds in coal?


Ally Stenhouse

Recommended Posts

Hi all, I have a "lump" of coal which I found at the side of a playpark many years ago and have never been able to identify the tiny fossilised things inside. I'll attach pictures I've taken down a dissecting microscope - the brown circular things are 1mm in diameter and the only other fossilised section is a 5mm wide length of something (possible plant stem) which is incomplete at both ends (and therefore not very useful). Hope someone can maybe give a suggestion or 2... Thanks in advance!

Also, sorry if pics not that good...

Welcome to the Forum. :)

 

Ostracods, perhaps?  

Maybe some "locals" can help. ;)

I'd go along with ostracods too, looks like Coal Measures marine band stuff I used to find in north England before all the mine tips were landscaped and tree covered. I've got a bit somewhere, will try to find it...

 

EDIT: probably not ostracods - see below...

 

 @Archie might know more.

Hi.  I agree that they are ostracods.  They are very common in some layers but extremely rare in others.

Hi.  Another possibility is plant spores, which are often found in coal rich shale.  I'll try to find a picture of one which I found.

Hi.  Here is a picture of two plant spores which I found.  They are useful for finding fish fossils as most of the ones which I find come from thin layers of coal-like shale from within coal seams, so once I have found a coal seam I usually look in the shale above it which usually contains fish fossils.

 

 

Overall I think your fossils are most likely to be macrospores, though ostracods are a possibility.

OK, I agree they don't look like typical ostracods, I rushed into that...

 

These are though, from the Coal Measures. About 1mm long (small divisions are mm).

Great pic,Tarq.

Namurian?

 

Thank you! Westphalian, almost certainly Harvey Marine Band which is on the A/B boundary. From a pit heap in Co. Durham.

again,from Hladil:

The association he documents is quite intriguing

Welcome to the forum from a fellow Fifer! :)

I agree with Daniel that these are Macrospores, when I first came across these in the Westphalian beds of Fife though I thought they were Ostracods because of how common they are in the Lower Carboniferous beds in my part of the county.

 

Regards,

Sam

Sorry I didn't tag you on this one, Sam. :blush:

 

Thanks for weighing in - I love when I learn something new! :)

No worries Tim! Me too! I only learned these were Macrospores thanks to @Strepsodus/Daniel showing me some of his specimens, its amazing how large they are!

Thanks for all the replies! Did look quite like an ostracod (especially maybe a Cypris sp.) But now that I look at macrospores I'm being swayed- easy for a complete amateur! Especially looking at the 1st photo, slightly left of centre where the possible macrospores has "creases" in it (if you know what I mean...

Anyway, thanks again.
