State: Iowa Location: Graf Period: Ordovician Cruised over to Iowa for the first time in years last weekend. I went to observe and scout the famous cephalopod beds in Graf. I have to say, it was everything I had hoped it would be. The wall in which the RC was located upon, was a few hundred meters in length, and contained a few layers, dominated by dolostone, limestone and towards the bottom, phosphatic shales. I ended up finding graptolites too, which I wanted to say were Orthograptus? However I didn't bother to keep any. These were most of my finds, minus the plates I took home as well. Here was the largest hashplate, I feel like slapping this one on my desk due to the sheer chaos it exudes. Here was an unexpected find in the form of three fragmentary trilobite pygidiums. I wasn't aware they could be found here, so I'm unsure of the taxa designation. The funniest about these was I found them all within five minutes of each other. 10/10 would gif gaf up in Graf again. Next time though, I want to see if I can locate some supposed Isotelus fragment beds up near Elgin.
