Is this elm or oak?

It's old enough to be elm, but, really I have no idea. Floor boards taken out of an 1800s house.

Thank you.

Oak 100% The medullary rays are a big giveaway.

As above 100% oak

Thanks to both of you.

...and for the next question -

The photo below shows the wood in the previous photos and, on the far right, some wood that does not seem the same -

Here are some closer shots of the right hand stack. Be aware that some of the darker colour is due to water.

These may not even all be the same, but they do not seem the same as the others (to me).

Thanks again!

Right hand stack looks to me like - Spruce / ash (sycamore?) / dunno (spruce again) / ash (sycamore?) / beech.

But I'm strictly an amateur at identifying wood.

Julian, often well-prepared end grain is the only way to get a decent ID on wood. The long grain often lies about what wood the board is, and that's even when the surface isn't rough or dirty ;-)

Between oak and elm, if you check images available online you'll see there's no mistaking the end grain of one for the other.

The 1st photo I would say was Beech or Sycamore, the rest was Oak again.
