Somewhat egg shaped fossil

What I think is a fossil was found in boulder clay cliff, when walking on the shore between Scalby Ness and Cromer Point, north of Scarborough, North Yorkshire. The object is grey colour, oval and measures about 11cm  by  about 9cm, and 7cm deep.  There's a shallow ridge around it. There are about four small shell-like

objects embedded in it.   I've search internet for a pictures of similar, but found none.  Is it a fossil ?   Please answer !

Tammy.

    Indeed, some more photos (different angles) would be useful.

    But I think it will turn out to be a concretion, the bands being primary stratification (bedding), which just happens to be intersected by its curved surface.

        Tammy,

         

        Concretions can have fossils inside them, so by all means go ahead and break or cut it open just to see. You never know... There's always the bit of excitement to think, if you do reveal a fossil, you will be the first one to see the creature for millions of years.

        Hello Tammy

        The glaciation period spread many rocks and fossils from Scandinavia, Scotland and other northern areas down the UK, the Holderness coast in my opinion is the best place by far to find volcanic rocks, lower, middle and upper Jurassic fossils, also Cretacous fossils.

        Also it is a good archaeological area if you know we're to look because of the rapidly eroding boulder clay cliffs.

        You have found a Jurassic nodule, not a 'cannon ball' (so called because of there shape from bed 33 cannon ball doggers Whitby)

        You can see the type you have found in situe in the cliffs around Whitby but also find them along the Holderness coast along with the cannon balls.

        Below is an image of a similar one to yours with an upper Lias, lower Jurassic ammonite inside of it called Harpoceras falciferum, not all nodules/cannon balls contain a fossil I fact sometimes you get fed up splitting them open to find nothing.

    This looks exactly like a Boji stone, you used to be able to buy 2 as a pair male and female, quite big about 15-20 years ago, I got two the size of an old fifty pence, heamatite like composition, they feel like 2 magnets pushing apart when held face to face. Good find they are collectable and saught after.
