Just wondering what this is

[andywain]

Hi

We were on the Dorset UK coast yesterday and found this embedded in what I think was mud and was wondering what it is. It's about the size of a thumb nail 

 

Many thanks

More and light pictures would be helpfull.

Before i try to Identify it, i want to see more pictures of it to be 100% (or not) sure.

There might be a slim chance of this being a coprolite. Honestly though, I'm afraid the odds of confirming it are slim.

Some objects similar to this are thought to be essentially natural extrusions of soft sediment through a capping layer.
