Is this a worm fossil?

[Pleuromya]

Hello, I noticed this looks like worm fossils, is it? I went to take some more pictures, but I think I've taken it away, so sorry that there is only one photo.

It is from Northamptonshire, UK, which is Jurassic in age.

Thanks.

Hard to tell from this picture. Close-up view of this fossil would help. Worm fossils are rare because soft body is rarely preserved. If it resemble worms, it's possibly burrows or crinoid stems.

Sorry about the picture, I'll see if I can find the fossil anywhere tomorrow. Also when I said worm fossils I meant tubes/burrows. Sorry for any confusion.
