What is white deposit on this orthoconic cephalopod? Should I attempt to remove it?

PS It fizzes in vinegar. Would soaking it in vinegar damage the fossil?

Most likely, yes.

This is probably the calcium carbonate that makes up the fossil, that has been weathered away by the elements.

Thanks, Tim. I'll leave it be.
