The creature shown in is an artist’s recreation.  The soft tentacle tissues have not survived and the squid-related animal may have had 6, 8 or 10 tentacles.  The sutures you see on the ammonite’s exterior are reflection of incremental growth, similar to the sutures on a human cranium.  In this item, the exterior of the fossil has been ground off to reveal the sutures.
