This is a beyond rare nautiloid that was found in the Oligocene of North Florida. We know of fewer than 100 of these having ever been found in Florida, this is the fourth one we've offered for sale - and it is by far the finest of those four. This specimen is located inside of a silicified concretion as is common for Florida-found specimens. It has been expertly cut to expose the nautiloid. The inside of the specimen features beautiful droozy crystals that pictures do absolutely no justice. This is an incredibly rare specimen that displays very well. These will be described as a new species by Dr. Portell at the Florida Museum of Natural History in a forthcoming paper.
