Nj Cretaceous Fish Scale?

[Fishinfossil]

 

Found a few of these over the years in Big Brook area, not exactly sure what they are?   They are concave as well.

Looks like it may be a ray dermal scute. I never found a fish scale from here.

Could be half of a fish/shark vertebra

I agree with Erich. That looks like an eroded shark vert. I have one exactly like it from Ramanessin.

Ok, thanks, most likely eroded vert looks like...also a nice little find today with this ghost shrimp/crab claw...

I agree with Erich.

Yep, Chondrichthyan vertebra and ghost shrimp pincer

Do you think we could see a pic. I still think it's some kind of scute/denticle.

If you compare this pic with a typical shark/ray vert they are the same

Here's what I believe to be a denticle/scute from a ray.

 I'm sorry, but it doesn't seem like a half a vertebrae. I have a couple and they appear different.

Maybe Fishinfossil would be so nice to show us the other "fish scales" he has found for comparison.

Nice pics. Thanks for clearing that up. 

 

So, has anyone ever found a fish scale from here?

You’re welcome. There is a common type of scale. It is usually a small fragment whenever found and has a shiny appearance with some small bumps. It is attributable to pycnodonts, so most likely Anomoeodus phaseolus.

Those rings are typical patterns of the inside of those verts.

Actually the pattern is that of calcified cartilage. Right ?

Not sure. But shark verts that are also calcified don’t have that pattern

I think it's more of an ongoing process than a fixed state.

Ongoing process of what?

Calcification is my thought. I think they get bonier with age.
