Shale/mudstone fossil or mineral?

I am back with another one I cant quite work out! Being quite amateur I am still learning, so apologies if I'm mistaken on rock type etc.

This was found on the jurassic coast of the UK, on the beach near Charmouth and is in shale/mudstone so already trying to break apart as you can see.

I've been wondering if it's a sponge or root of some kind, or just mineral like pyrite as it has a goldy metallic sheen in some light, although it seems too brittle for that and has got what looks like more calci(?) layers when I look at the ends.

Any help from all of you lovely lot would be greatly appreciated!

Side note: if it is a fossil is there a good way to preserve these delicate shale ones to avoid the crumbling? I've been looking at the guides but there is so much information I might be tying myself in knots a little

There's a lot of marcasite/pyrite to be found in these layers along the coast and this is what it is.

Thanks so much! I suspected as much but started second guessing myself (wishful thinking!)

I agree with Roger. It may well have formed along a burrow - organic matter decay often initiates pyrite formation.

Sure! I was wondering what this might be actually!

It's a worn shell, probably a brachiopod.
