Bulletin 145

Figure 518. Straight nautiloid in the lower (deep-water) part of the Famennian reef (Windjana Limestone) on the south side of Windjana Gorge near the west entrance. The nautiloid is oriented with its apex upwards, probably as a consequence of gas in chambers that were afterwards filled with calcareous sediment and sparry calcite.

But this is my own photo of the beasty!

Nice shot. Looks like a Dipleura trilobite, but I have only seen these from the U.S. Maybe a few of them headed south!

Thanks for your comment. It is actually a nautiloid - but don't take my word for it - see my new improved description of the photo.

Thanks for the clarification. I don't know if you imaged searched Dipleura, but you can easily see why I thought it might be this trilobite. Don't mind me if I show a little favoritism!
