Found in a house clearance in the UK so have absolutely no idea where the fossil originates from.

Hi, 

never posted before so please bare with. 

Found this fossil in a house clearance (Uk). 

It's sandy in colour across the surface and an off white (chalky) colour in exposed areas. 

Have included a tape measure in the pics for length (approx 10 inches).

both sides (as shown) are deeply textured and it measures 3.1/4 in depth at its deepest but does taper down. (Hopefully shown in pics). 

 Would really appreciate some help with this. 

PS each "segment" is divided by a very thin, but clear ridge/seam. 

Thanks all for your help 

Any more info required, I will do my best. 

Many thanks.

Welcome to TFF!

Your rock does not look like a fossil, it appears to be lithofied mud cracks.

Could be an extremely weather and water worn septarian concretion

Looks interesting, but I agree, not a fossil.

Not an ironstone nodule ("crocodile skin") but a nice septarian nodule/concretion, because there are propagation cracks filled with crystals forming walls, probably of calcite.

thanks for your help guys, much appreciated!

have searched the terms you have given and compared it to many images.

It would seem to be almost certainly a septarian nodule/concretion as suggested. 

It makes for an interesting display piece for sure and now I can chat a little about it thanks to you fine people : )
