Helicodromites mobilis, Cast of Shark Egg Case, or Other?

Recommended Posts

Hi all,

 

I just acquired this interesting specimen that was identified by the seller as Helicodromites mobilis. However, when trying to verify this, the images and description I've been able to find really don't seem to match. The whorls on this are flat and attached to the core. To me, it looks more like a cast of a shark egg case. Are any of you familiar with H. mobilis? Thoughts?

 

Thanks for taking a look!

That looks more likely than H. mobilis.

I don't know that it is an egg case, just that it looks similar to one. I just love anything weird and unusual!
