No idea but its curved and porous.

I was sifting through my old finds in Big Brook and there was this curved item that was about an inch long. I have 3 pictures attached. Big Brook is known for marine type fossils. Not sure if its even identifiable but it is porous. Any idea what it could be?

It's trying to look like bone, but I don't trust it. The brooks are full of concretions that want to be fossils.

Haha true, I found quite a bit of concretions of my trip there

But it is very light and if I look closer there are a lot of pores, many of the concretions I found seemed to be much heavier.

The bone pieces that I collected there were well mineralized and so quite hefty. There are younger deposits which sometimes show up in the brooks though. Some of the locals should be along eventually.

My initial feeling was petrified wood (just collected a bunch this summer in the Blue Forest and had very similar pieces) but unlikely at BIg Brook. Can you provide a close up showing the porous structure. It will help the experts provide their best identification.

Hey Mike, yup I can take some close up photos of the porous structure, gimme a few mins

It is definitely porous, im not sure if the image I attached was alright. When I stick it to my tounge it does stick for quite a while, google said that was one way to distinguish small marine fossils from plain rock.

My best guess is that it has smoething to do with a ray/skate.
