Hi, I am in search of Plate 8 from the following paper. Yes, the paper is published online at Biodiversity Heritage Library, but both Plate 8 and its accompanying "Explanation" (i.e., captions) page are unfortunately missing from the online edition. Please post a scan if you have easy access to Plate 8 from this paper, thanks. Driscoll, E. G. 1965. Dimyarian Pelecypods of the Mississippian Marshall Sandstone of Michigan. Palaeontographica Americana, No. 35.

Hello! I would love to have more info about this interesting fish bit that a paleontologist friend and I found a couple of months ago near Jackson, MI, in a glacial dump of Marshall sandstone. This little cobble was already broken as it appears, and we couldn't locate any other pieces of it. We're certain it's bone, and that it most likely came from the pectoral girdle (or pectoral spine area) of a bony fish. I looked through the list of Mississippian material found in MI from the Geology of Michigan, and noticed that while it describes lots of Chondrichthyes found in early Mississippian rock, no Osteichthyes from the Mississippian are recorded in that book. The closest match my friend suggested was Psarolepis / Andreolepis ( https://www.nature.com/articles/17594 ), but if this is the Marshall sandstone as we are sure it is, he says those genera would be far too old. Any thoughts would be welcome! (P.S. The second photo is a stereophoto.) Thanks, Lisa

Today I had an unusual opportunity to access a site rich in local Marshall Sandstone (Early Mississippian) bedrock as well as local-origin erratics of the same here in Michigan. Much of the bedrock in this area is covered by up to 100s of feet of glacial deposits. Look at the size of this chunk I was able to bring back. It's basically a "coquina" of molluscan and brachiopod shells. I think I have some new hernias now as a result of carrying this thing back to the truck (just kidding - I think...). I didn't have the aid of the wagon until I got back . But it was an exploratory trip and I didn't quite expect anything like this: Here is a close up of how rich the material is:

Not a fossil but they're on a fossil I thought I'd share a photo of these neat dendrites I found this evening on a steinkern of a Mississippian Paleoneilo clam from the Marshall Sandstone. Scale in mm
