Cretaceous Shark australia

[Mike from North Queensland 382]

Hi all I picked up this broken specimen out at Julia Creek (Western Queensland Australia) a short while back and assume it is a small shark Vertebra but would like conformation as it is worn.

The formation is cretaceous around 100 million in age - I still have to confirm the formation as I have never fossicked in the spot before as it was a short stop for lunch on a full day drive.

The specimen if whole would have been about 22 mm in diameter so is small. There appears to be quite a few growth rings so this may have been a quite small mature shark ? (Bramble)

It looks very much like the shark verts I find in Texas.

I agree with jarodB looks like the shark vets I find in Florida. Nice find

A view of the outer edge could be helpful. I don't think it is a bramble shark, Squaliform sharks have very simple centrums that are basically two cones attached at the points. Squaliform centrums are very fragile and don't fossilize well.
