Didymoceras? Seems a little too perfect but I'm not complaining most photos I've seen they seem to skew out at the top

From the Pierre Shale in Boulder Colorado. Just wanted a second pair of eyes to take a look.

Wow!  That is a spectacular find.  As for skewing out , this amazing spevimen is missing thst part.  In many of the ‘perfect’ didys you see the smaller whorls are reconstructed.  
 

can you hear the jealousy in my voice?
