Fossil wood?

[mr fossil]

Hello

i found this peculiar fossil while looking for late neogene coral fossils(which I found) 

I’ve fossil hunted in this area for years and haven’t found anything like this so I was thinking maybe this is petrified wood from when Arabia was green 15-4000 years ago 

what are your thoughts? I would love to know 

thank you I appreciate it

Maybe a piece of echinoid spine?

I agree it is a spine from an echinoid.

I don’t think so cause I’ve collected many echinoid spines and they have a inner pattern and are totally smooth from the outside but il look into it 

thanks

In addition to the decorations along the spine, we recognize the sea urchin spine which is often calcite at the angle of its break (photo 2).

 

For your future photos, read my last link in my signature. If you don’t have a ruler, print out my handout and put your fossils on it before taking your photo, making sure to leave one of the size boxes visible
