Is this Septarian? Help please

[Leabutterflies]

Hi - first time posting ☺️✌️

Could anyone help me identify these rocks? I was told they were Septarian, then by others told they are not.

Thanks so much

Where are they from (rough area, nothing prcise)? That sometimes helps if sepatrians are known from the region.


They don't have the classic webbing on outside but still similar enough to pose the question. Could easily just be concretions or standard nodules.


But I wouldn't rule out septarian nodules. Only cutting will give you a definitive answer.


Cheers,

Hi,

Thanks for your reply. They come from the Richmond area in North Qld.

Thanks so much

There have been occasional septarian nodules in that area. Nodules are common in the area though
