Large Nautilus found, ID please.

Out hunting today on Whitby Jurassic coast and came across this beauty, measures 10", now I have came across bits n pieces of these in the past but never a complete specimen, does anyone know the name and how would I go about prepping this ? Worth polishing for best results ? Thanks.

I wouldn't polish it. What have you got on it right now, some sort of glossy coating, or just water?

Hi, just water as soaking it, thanks.

Oh good! Nice find, in any case. I can't say I've ever found a complete nautiloid over here in my Santonian strata. Just partials.

Do you know the epoch, as in Early/Lower Jurassic, Middle Jurassic, or Late/Upper Jurassic?

Are you absolutely certain that you have a nautilus there? I'm thinking that I can see the sutures of an ammonite on it. The whorl breadth is also extremely narrow for a nautilus.

Roger, I agree with you. My first impression was ammonite. Either way a gorgeous fossil.

It wouldn't be a nautilus either way, that's a recent genus. It may be a nautiloid even though the whorl profile is more narrow than some but I can't see the sutures Ludwigia sees to tell. It is very involute so if it's an ammonite that would have to be a character to be considered. A good id may come from someone familiar with the Jurassic fauna from there.

I noticed the same thing and I thought I amended my post above to ask the same question, but I guess it didn't take.

Hi, just can't see anything similar on Google, once it has soaked I will use dental tools to reveal the centre, it came from a recent cliff fall.

Check out Phylloceras. I think I can see the typical striations on the outer living chamber.

I've used some dental tools on it and revealed more pattern, also removed shale around it, has what looks like a crack running through top part but is still in one piece, surprised it stayed in one piece after the fall tbh, will post pics up once dried out, thanks.

Bit of dental tool work and coming out nicely, lot of work involved slowly prodding away the mineralization but worth it in the end for sure... :ammonite01:
