Looks amazingly like a blackberry....

The leaves and the fact that it has thorns remind me of a Rubus.

That is some kind of thorny berry.
I swear its a blackberry too.
The leaves give it away.

Could it be a dewberry? I get them around shrubs and have the devil of a time getting them out.

I can't see the thorns on yours. Dewberries have hair thorns, like a dandelion.

I don't intend to identify this, as blackberry and dewberry are closely related, and I have never seen dewberry.
What I would like to ask marti8a is about dandelions with hair thorns. The dandelions I know, from UK and Australia, have no thorns, hairy or otherwise. Can you please ID, with latin name, as you have got me really curious as to what plant you are describing.

Have a good day

Fof

Rubus species - impossible to tell which one from the pictures but almost certainly not something you want unless you have lots of space and want a wild berry patch.
