Hi, I found this on Seaton sluice beach in Northumberland. I think the rocks are carboniferous in that area. Can anyone tell me if it is a fossil and what it is?

Welcome to the forum. I hope Tarquin Bolton looks at this post as he knows a lot more than I do about it, but to me this is saying " mineral veining" rather than 'fossil' I'm afraid.

Thanks Colin! Hoping someone could shed some light on it

Agree. Very pretty though...

Saw this on another group - the way the branched pattern seems to be just on the surface of a curved, worn block suggests it's marks left by a modern encrusting organism of some sort. The last photo does look as if some of it could be internal though - hard to be sure. 
I admit I've seen nothing quite like it before.

Thanks Tarquin, looking closely at it the marks seems to be 'in' the rock rather than 'on' the rock. I think I might take it to a local geologist for someone to properly inspect it as you'd suggested. Thanks!

Thanks Tarquin. Looking closely it seems the markings are in the rock, rather than on the rock. However, think I'll take it to someone local who could have a proper look at it. I'll let you know if I get it identified either way. Thanks for all the replies!

Thanks Tarquin. I've taken your advice and emailed a few pics to a local geology group to have a look at it, will let you know if I found out what it is. The marks do seem to be 'in' the rock, rather than 'on' the rock but as someone with zero knowledge I'll see if I can find someone local who I can take it to. Thanks for replying

Thanks Tarquin. I've contacted a local geology group to see if there is someone I could take it to. I'll let you know if I manage to solve the mystery. Thanks for replying

This may possibly be some type of plant imprint, but it could also be a dendrite, a pseudo-fossil.  A pseudofossil is an object that is often mistaken for a fossil but is actually inorganic. The example below may look like fossil fern, but it is instead a set of beautiful manganese dendrites.  What is the age of the area in which you found your sample?  Were there other examples like this nearby and, if it is in fact a fossil, other types of fossils in the same vicinity? ---- Gerald

Thanks Gerald, yes could be a pseudo fossil. Here are some pictures of items I found today in the same area.

What is the age of the site?  These look like plant fossils. I'm not sure what, though. The fossils are badly worn, but they look familiar.  I have to go eat dinner.  I will do some research afterwards and get back as soon as I can.

These look like the first set to me - mineral.

 I agree with Colin.  Sometimes such mineral deposits can have such bizarre shapes and be so unique they are actually more valuable than actual fossils.

The latest photos also seem to show the patterns extending around the surface of worn rocks - they look superficial.
