Platyceras (Spiniplatyceras) arkonense (Shimer Grabau 1902)

I just love the clustering of this trio, almost as much as I adore that one of them is playing cornucopia with a whole lot of crinoid bits! 

Umm... I count 5 on there.  

You're right! I was just counting from the thumbnail image.  

You're right, Tim. I just posted the complete block as an afterthought after I'd written the script. This is actually my favorite from that trip.

Thats a nice hash plate!

You said it, Jim
