  1. This past Monday, during an outing to a quarry with Dave Broussard, our very own Tim (Fossildude19) and Paul (Paul1719) in PA. I found a partial ischnacanthid fish jaw. As it was only the second known from that location I donated it to Dave for study. A few moments later Paul found one too! He also donated his. It was interesting and enlightening watching a professional photograph and preserve it before removing the part of the slab it was in. Dave is a professor at Lycoming College in PA. and a vertebrate paleontologist. Ischnacanthids had a primitive ar
  2. I managed to actually take a vacation last weekend and meet up with our very own Tim and Paul to collect Late Devonian verts from PA. I first met up with Paul at Red Hill. When I first arrived at the site I didnt know the person there was him. So I parked and walked into the ditch at the base of the road-cut and immediately spotted a strange form in a piece fallen from above. As it turned out it was a Gyracanthus spine! Gyracanthus sp. Turns out the mystery collector was Paul, who was kind enough to give me a rundown on the site, its geology, and show
  3. Over the past year, I've become fascinated with the often bizarre fish and sharks of the Pennsylvanian. Fortunately, my home state of Illinois is a great place to hunt for such fossils. I've shared several of these in other posts before, but wanted to put everything together in one thread. Probably won't have much to post for a few months after this, but once summer rolls around, I should hopefully have plenty of new finds to share. I would say there are three major settings in which you can find fish fossils in Illinois: Mazon Creek, black shales, and limestone. I have not had luc
  4. Hi Everyone, I’d like to share a few posts on the shales I’ve been hunting recently in Kansas City, Missouri. Long story short – my neighbor is digging a ‘pond’ to China. He has massive equipment from his business and so far he’s dug through about 35 feet (~10.6 M) of material. My land matches his where the dam to the pond is and I saw shale in it which really surprised me since I’ve never found shale on my property. Even in the creeks and gullies. I would also like to say that I have been really inspired by the posts from @connorp and @deutscheben about the shale they find in Illinois
  5. So an interesting summer. As some of you might know, Parks and Recreation came down hard on the Red Hill site while I was working there. At some point, the site had been transferred to Forestry, ya go figure. So there has not been an active permit for some time. But I was homeless and in need of a project so I was able to connect with Prof. Dave Broussard of Lycoming College and shift my focus to the sites along Rt 15 north of Williamsport. Still Catskill although the exposures at Powys Curve are Sherman Creek (Frasian) member instead of the Duncannon (Fammenian). I had collected there with my
  6. Did some fossil hunting at the tillywhandland quarry near Forfar during the weekend and found of partially exposed acanthodian fossils. I just wandering if anyone could give me some advice on how to expose the fossils without damaging them. Someone mention that I could use acid to expose them, but I have been reading that potassium hydroxide could do just as well. The fossil are in clastic carbonate laminates.
  7. These are a few of the pdf files (and a few Microsoft Word documents) that I've accumulated in my web browsing. MOST of these are hyperlinked to their source. If you want one that is not hyperlinked or if the link isn't working, e-mail me at joegallo1954@gmail.com and I'll be happy to send it to you. Please note that this list will be updated continuously as I find more available resources. All of these files are freely available on the Internet so there should be no copyright issues. Articles with author names in RED are new additions since April 2
  8. A new study led by the American Museum of Natural History (AMNH) provides the strongest evidence to date that sharks arose from a group of bony fishes called Acanthodii (‘spiny sharks’). Analyzing a well-preserved fossil of Doliodus problematicus, a sharklike fish that lived 400-397 million years ago (Devonian period), John Maisey and co-authors identified it as an important transitional species that points to sharks as ancanthodians’ living descendants. http://www.sci-news.com/paleontology/sharks-acanthodians-04706.html

    Acanthodian Spine, Devonian, Maider Area

    Hello, this is a fragment of a large acanthodian spine. Length about 16 cm, width up to 2,4 cm. All I know is that it's from the devonian of the Maider area in Marocco (scale = match = 45 mm). Does anyone know more about that material from Marocco? (Genus, more precise data about the stratigraphic age?). I think it's probably Machaeracanthus, but I'm not sure. Thanks, araucaria1959
