Is this a nautilus fossil?I don't have any informations about it,I guess it's from Madagascar?

Thanks everyone

Yes, Nautilus. But not sure from Madagascar

[Rockwood]

I don't know about Nautilus, but it should go nautiloid I think.

I would say at least order Nautilida, family Nautilidae. Couldn't guess the provenance though.

It doesn't look like a typical Madagascan specimen, or not the ones I've seen. 

No saying it isn't, mind you, I have no idea where it's from.
