Tidgy's Dad Posted April 13, 2022 Share Posted April 13, 2022 Mudstone / siltstone, I think. Not sure about the inclusions, the middle one might be burrow casts? 1 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I agree but when I saw it under a microscope I could see grains of quartz sand Link to comment Share on other sites More sharing options...

Interesting.. do you think the supposed branches are actually fossil branches? and what paleo environment did it form in swamp? Meadows maybe ?

Meadows maybe ? No, I think they might be infilled burrows of some kind. Sandstones can form in all sorts of environments, but I doubt these formed in a swamp, certainly not a meadow. Mudstones form in places where mud or clay accumulates, usually in oceans or lakes. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
