Please help identify this.

Hi there, a friend found this object on their gravel drive recently in Suffolk and wondered what it was. Is it a fossil? It weighs 125 grams, has a diameter of 5 cm and a circumference of 6.5 cm. It seems heavy for its size and has a rusty look about it although it is not attracted to a magnet. The top is domed and its circumference seems remarkably circular. The outer surface is covered in small striations which look organic in origin. Underneath there appears to be the remains of a bi-valve. Any suggestions please. Many thanks.

    Very strange!

    Unusual surface texture, and very close to spherical in arc, as you state.

    You might need to bring/send this in to the IAS (Identification and Advisory Service), Angela Marmont Centre, Natural History Museum

    It's a nodule that contains a lot of iron pyrites = weight, that is erroding probaby because of the location the gravel came from that covered the drive.

    Also it contains a fossil bivalve ie mussel, clam, etc you can see two halves that make up the shell in the last image.

    I remember a topic on another fossil forum about what people had found on there gravel drive ways, there was allsorts of fossils, ammonites, belemnites, bivalves, sea urchins to name but a few - nothing like your's though.

    well done very interesting.
