curious Fossil mineral combo

Can you help me with this curious mineral/fossil combo please?

It's oval shaped, reasonably regular, greyish in the most part, I guess weighs about 3lbs (1.367Kg). It looks just like a normal big pebble, yet there are a couple of really interesting features.

On the top there's a group of fossils, smail-like. However their lustre makes them seem almost metallic.

Similarly 2 thirds of the way down the side, there is a band of what appears like metallic crystals attached (not fused) to it. The band is brittle, and I have broken a small piece off. It has a crystalline structure, and from what I can see with a magnifying glass it looks silver in colour.

It's so metallic looking I tested with a magnet but it is not magnetic, though some of the colouration looks like rust.

It is from near Staithes in North Yorkshire.

I'm not really a fossil hunter but this has got me really curious. I'd love an explanation if you have one!
