Is this fossilised tree bark? From Robin Hood's Bay, UK (Jurassic)

[EntomoloJosh]

Hello,

 

The other week my girlfriend and I took our first trip to North Yorkshire Moors and of course we went along some beaches for fossil-hunting and came away with quite a bit. I'm fairly sure on rough IDs for most of them, but I'm not sure on this one, which was collected from a a rock along Robin's Hood Bay. The rock containing the fossil looked a lot different from greyer rock that was along that beach, with this rock looking relatively pale (I don't know if that actually means anything, however). I initially thought it was bone, but I think it might actually be tree bark?

 

The fossil itself is quite flakey and delicate, and has a bit of a reflective almost velvet-like sheen in certain angles of light.

 

I'd love to know what it is!

Thank you!

No. I think it's fossilized wood though.

petrified wood. Nice find, there is a layer with petrified wood, not good exposed. So you had luck

You've got wood. Nice specimen.

Thanks for the ID all! My first piece of fossil wood, so very happy!
