Can anyone give me any details on the make up of this fossil?

It has a very heavy and smooth rock in the centre, then a crystaly layer, then the layer with all the small fossils in it!

I don't know a lot about what I'm looking at so any information would be good.

Hi Ash,
That looks like a shelly limestone with calcite vein. If you said where you found it and included some kind of scale that would be a big help. I see broken bivalves and maybe gastropods in a lime mud matrix.

Hello Ash and welcome to the forum. I agree with Pete, we need more information and photos (with a scale and a ruler is best).

Thanks for replying, I will take some better pictures in the day light tomorrow and give you some dimensions.

Here are a couple of better pictures, a ruler included in a couple to give an idea of size. The whole piece is about 6 x 4 x 4", the central rock measure about 3" diameter and if very smooth. Does anyone know what the central rock is and why it has the layer "calcite" around it?

It was found at the bottom of a cliff face along the solent in Southampton, Hill Head to be precise, there has been a lot of erosion lately due to the weather. Is it worth going to look for more? After having a good look once finding this piece it seemed to be the only bit around!

Thanks

Hi Ash,
You're on the Tertiary Bracklesham beds down there. The central rock is probably a mudstone nodule and calcite has been deposited from circulating carbonate rich fluids at the interface/crack. Plenty of gastropods/bivalves as previously mentioned. If that type of rock isn't present in the cliff I guess it must have been washed up from offshore maybe.

Thanks Pete, 

It's nice to get some information about it, if nothing else it has raised my interest in finding some more treasures. Just got a dog so I will be keeping my eye open when out and about now.

Thanks again, 
Ash.
