Aust: Fish Scales?

I am dissolving a bit of Aust and found these: Would I be right in thinking these are fish scales?




and



Any ideas would be grateful


Found plenty of little teeth... this is the smallest tooth I have managed to find... 0.79mm !!

Maybe, there are 3-4 major scale groups though.. I'll check my VP notes on fishys and get back to you Got anything a little more in-focus?

Thanks Macro... nope that is as focused I could get it.

The scales are Gyrolepsis albertii.

Can't make out any distinguishing features on the tooth I'm afraid but possible Severnichthys acuminatus.

Be on the look out for Hybodontid scales as these are very distinctive and quite interesting.

Yep. Those are definitely fish scales.
