Tiny opal fossil

Recommended Posts

Woogie

Hello hello, recently i bought some opal, in amongst the small stones was this.

I am wondering if this is a fragment of bone? Maybe a piece of jaw bone?

Its from Coober Pedy, which i believe is cretaceous and marine

Ok, hope these are ok, difficult getting decent close ups. 

1st pic, looks like they might be teeth sockets

Hard to see, but in the last picture you can just about see its hollow and the matrix runs through it

That may be some of the clay/sandstone it's formed in. A lot of the opals have pockets and/or layers of it in them.

Sorry, i am not great at wording things! Im with you though, this came with about 50 other small pieces, most are bits of bi-valve shell i think, some quite interesting looking with holes filled with the matrix, this piece was different though.

The holes look like they might be teeth sockets, but the shape of the holes make me think it might not be, especially as it would be marine, i would imagine circular holes?

Also it is hollow, like i would imagine a fossil bone to be, dont know if a jaw bone would be hollow though? Or a piece of shell? 

Spent a while searching google but cant find anything like it

Congrats,

this is a piece of a heterodont lower jaw bone of a cretaceous mammal. Rarer than reptile finds in opal.
