What is this object I found at our allotment?

[ferretface]

Hopefully pics will work....

Hand for scale

Oh that second pic doesn't seem to have worked. Object is about 3cm across

Button?
What's it made from? It is metal or stone?

Is it hard like a rock or soft?

Was it buried?

Shell or sea urchin outer case?
Are you near the sea?

Sea urchin shell

Looks like a weird fungus.
Wash your hands

Somebody’s sourdough bread that didn’t quite work?

I thought it was a sea urchin too.

Like this

It was buried. It's hard like rock, definitely not a fungus!

Dropped by a bird?

Nowhere near the sea! It is solid - not hollow, would a sea urchin shell be solid?

It's a fossilised sea urchin. Sometimes kept for good luck. Google Fairy Loaves!

Just tried a google image search on it. Google has confirmed it's most definitely a loaf of sourdough!

I really want to know what it actually is - I love found objects.

Here's the base...

I thought it was a fancy jacket potato until I saw the second photo showing the size 😳

If you have twitter you could tweet museums and see if they know the answer? How fascinating.

Wow I think it is a fossilised sea urchin or fairy loaf!! @udnertheradar I think you've successfully IDed it!

It’s a fossil!

Alien poo.

Ooooh, what @udnertheradar said! It is a fairy loaf, amazing!

Definitely fossil sea urchin- here’s two of ours

It’s a fossilised sea urchin. When I was a kid we dug one up on my
Dad’s allotment. My brother still has it on his mantlepiece.
