The second page is a sort of "map" to the classifications used in the various sheets over at The Compact Thescelosaurus, made with classic ASCII cladograms. (I contemplated drafting them in other ways, but none of them were as amenable to updating.) I thought this would be useful for visualizing the mess of classification columns. The process also forced me to look at the positions of a few clades, as you may have noticed from the updates sheet.
It's not connected to either topic, but I've also added a paragraph of new information to the post on the "Kweichow sauropod" after coming across a mention of it in Averianov and Sues (2017).
Finally, so as not to leave the post without an image, here's one attached to a quick story:
Back in spring 2001 I was on a field trip to the Badlands/Black Hills area of southwestern South Dakota. We were stopped along a road near Deadwood for lunch. One of the professors said something to the effect that "there are fossils in this formation." I looked down at the chunks of rock at my feet and said "You mean like this?"
|Yeah, like this.
From my notes the source is the Whitewood Formation (or Dolomite, or Limestone), fittingly enough an (surprise, surprise) Upper Ordovician unit. More on its cephalopods can be found in Miller and Furnish (1937).
