Layered sponge?

[mighty micraster]

I found this in late cretaceous flint, wiltshire, UK.

Struggling to think what could have made these layers, and it's shaped a bit like a sponge?

Its not layered on the inside as well.

Sorry if my photos are a bit blurred.

Each layer is about 1mm thick.

Hi did you find this a field?

 

It has the appearance of a flint burnt, when stubble used be burnt by the farmer...just a thought..

 

Thanks

Yes, in fact the current owner used to burn EVERYTHING.
