Uncertain?

Hi,

I am new to your site.

A friend gave me some stones he found in outback QLD Australia some time back. I am a Certified Gemmoligist and occasionally I go fossicking. I am also interested in Fossils.

I have attached photo of the material and I am asking if someone could confirm what I am seeing.

belemnite?

I'd put money on it. Overall shape and crystal structure are a match. Knowing the age depositional environment of the rock it came from would help confirm.

OK, that has turned my head another direction.

I originally thought it might be a tooth or a tusk.

There is a 'line' running down either side of the 'tube' which I think is similar to other belemnites?

I am sorry but I do not know the age of the depositional rock or the exact location, my friend likes to explore areas that are quite remote.

The crystal structure is radiating inside the 'tube' to the outer 'skin' - which I am guessing is calcite?

Belemnite, all the way. The deposit must be marine, and date from between Lower Jarassic to Upper Cretaceous.

That radiating structure was the crystal structure I was referring to. A big giveaway for belemnites.

Im also calling this a Belemnite. The radiating sprays are typical of the Aragonite that most of them seem to be comprised of.
