Fossilised wood?

[Cortinarius]

Hello! I hesitate to post after my last terrible misidentification of fossilised wood, but your kind help made me study harder, learn more, look harder - thank you!
 

So I’m back with another request - I think I might have actually found wood this time? 
 

These are all from the Kimmeridgian Helmsdale Boulder Beds or nearby Portgower Boulder Beds, Scotland, UK. 

 

Dark photos are wet, mostly they go quite pale when dried out.

In this case, I know wood is a known find in these areas, and I’ve found a scant few photos from seasoned collectors / geologists of finds from these locations said to be fossil wood that looks similar. But I’ve turned into the biggest pessimist and there was only a small amount of info to go on. 
 

If anyone would be kind enough to just confirm either way, I’d be so grateful (thank you!).

Well done. Sure looks like wood to me.

These do look like cobbles of petrified wood . . . stream-rounded cobbles after the wood was permineralized.  Interesting finds from the Jurassic period.  Is this your local geology?

Thank you so much! I’m very grateful for your help. 
 

This is quite close to where I live, yes. Although I have nearer fossil beaches too.  I’ve lived here 20 years and I’m only just beginning to scratch the surface of the absolute wonder there is in the rocks around here! We’ve got Devonian fish and tetrapod trackways, as well as several Jurassic locations within 30-45 mins travel. I’m trying to learn and investigate my way through it all. 
 

I’ve been trying to wrap my head around the geology of the Helmsdale Boulder Beds for a while now - it’s so complex! I find I have to be careful who I’m reading and when, and who they are referencing, as opinions about these formations have changed a lot over time it seems. Groups of geology students from various universities regularly get taken to Helmsdale as part of their field studies, as it’s such an interesting site. 
 

Thank you for mentioning the water smoothing - I was wondering about that and wasn’t sure if that was the right way to read it.
