I found this rock washed up in the sea at West Bay Dorset in May 2012 after storms. it looks to me like snake like creatures wriggling in the mud. Know nothing about fossils. what do you think it is?

Your specimen is rather vague, but I am fairly sure it is part of a fossil ammonite (not a snake).
You may expect an ammonite to show a spiral, whereas yours shows just an arc.
The arc may be due to:
- that being the actual curve of the ammonite (see heteromorph), or
- because you are seeing just an outer spiral (the inner ones not being as 'thick', they don't show)
They are known from West Bay
Got this 'Snake' fossil in a trade a long time ago and could have swapped it for things for my collection on more than one occasion but I like it too much.
