Welcome!

It’s an ammonite, preserved in the block and partially eroded by the sea. What you’re seeing is a cross-section. If you held an ammonite vertically with the coils facing left and right and sliced through it from top to bottom this is the cross-section you’re seeing. The cross-section nicely shows the chambers of the coils.

Hello Catherine and welcome to the forum. This is a nodule with an ammonite  (pr a part of one) in 'longditudinal' section. Nice find!

Its a cross section through an ammonite, couldn't tell you the type though.

To understand where we are going, we need to know where we have been.

It's a nice cross section of an ammonite, but I have no idea what species (others on the forum are more experienced with Jurassic material, so may help there).

Hi Catherine, it is an ammonite, seen from a slightly unusual angle. The ammonite is lying in the rock and you are viewing is edgeways. Part of it has eroded away to reveal the chambers within, which is what you can see here. 
Cheers,

Mr P.

Hmm, this system of pre-moderation seems to be leading to lots of repetition as no-one can see what others have written and then everything appears at once! Not going to be good for free flowing chats either.
Cheers,

Mr P.

Hi Catherine
The nodule is possibly worth being prepped properly. If approached from the non-worn side, a decent specimen might well emerge.
It's likely to be a nodule from the Green Ammonite Member, which comes down to beach level closer to Golden Cap because of the eastward tilt of the rocks here but many fall from the bed above. Ammonites within are most usually Androgynoceras but it's certainly worth investigating further.

Totally agree...

Thanks all for your replies and for shedding light on our find - as novice fossil hunters we were totally stumped as to what it was.

Microderoceras?
