  1. Last week, after checking the weather wunderground numerous times, I decided to drive 3.5 hours from Chicago to St. Paul Stone Quarry. It was the last "open house" day according to the ESCONI website. I arrived at 7:45, the first and only person there. Shortly thereafter, after a brief safety instruction, I followed the manager to the collecting site, heaps and heaps of Waldron shale. Even though I dressed in layers, I still had to take breaks and warm up in the car for a few minutes, but I much rather prefer collecting in cold weather as opposed to hot summer sun with mosquitoes, any day. It didn't take too long to start finding fossils. Here are just a few of my finds: Eospirifer Platystrophia brachiopods with pyrite Platyceras niagarense encrusted with strophomenid, bryozoa and pyrite. front: back: Partial Dalmanitid Trilobite in matrix When prepping, it's really wonderful how the waldron "butter" shale just crumbles apart around the predictable morphology of an enrolled trilobite. The trip just wouldn't seem complete without a short drive east to the Cincinnati Arch roadcuts. I first went to South Gate and found a flexicalymene eroding right out of the cut. It is interesting to see the comparisons here. The trilobite on the left is from St Paul (Silurian) and has beautiful pyritized eyes. The one on the right is from South Gate (Ordovician). Both trilobites have 21 articulated segments; does this make them both the same age as "adults"? Interesting to note the difference in size, being 40 million years apart, same species.. Thanks for looking!
  2. This is a Pennsylvanian age Mazon Creek type nodule found in Indiana.It may be plant material that is decomposed beyond recognition but thought I’d post it to see if anybody thought otherwise.I haven’t found any fish scales in this location but wondered if this might possibly be a scale.

  9. My kid and I headed north to see my family and friends in Cincinnati over TG weekend. And as they all have come to expect, I have a habit of slipping away at some point each trip to conduct sorties and surgical strikes on various fossiliferous exposures. This time, I was able to talk my friend Joe into getting up early and coming with me. Joe and I have been through a lot over the years. We've been friends since I let him cheat off my homework in 3rd grade, circa 1978. I stepped in a few times when kids tried to mess with him in grade school. We conspired to torment substitute teachers together. We've served as best man for each other over the years, and I was a pallbearer at his dad's funeral. The decades have a way of binding buddies together through thick and thin. In that spirit, I endeavored to take Joe to a slam dunk site, help him get acclimated to the presentation of fossils, and then turn him loose on the sweetest stretch of the exposure. So at 5 a.m. I kicked his door in and whisked him off to the Mississippian aged Indian Creek Shale of southern Indiana a little west of Louisville. With a bit of a car ride ahead of us, we had fun recounting the various misdeeds of our misspent youth, throwing around horribly inappropriate humor, and somehow, in the end, solving the world's problems. OK, we are there now. Time to grab some tools and start climbing.
  10. I recently was able to stop at the well known ordovician roadcut just north of St Leon in Indiana. What a wonder. I was able to be there only an hour, but it was fascinating. I was able to find these nice brachipods, but would like to label them correctly and so far books haven't helped me...I thought perhaps someone would be familiar with the brachiapods from that road cut and help me out. thanks. the people on this site are always helpful, and knowledgeable and so it is exciting to be a part of it all. The Brachiapod labeled 6, a,b,c are obviously three different views of the little guy. the coin for size in the edge of the photos is a dime. This brachiapod is so cool, one can see the opening edge between the two halves..so cool.

  17. Those of you with keener memories may remember that I posted about a trip to Sulphur, IN earlier this year. After that trip, I've been wanting to get back pretty badly, dreaming of finding another shark tooth. Columbus day and the cool weather got me back down there on Monday. Like a trained dog, I headed right back to where I found the tooth before, knowing that it was improbable that I would find another. Within 30 minutes, I came up with this: This appears to be a mostly present disarticulated trilobite. Any ideas as to species? My previous trilo tail was thought to be Paladins Chesterensis. This matches pretty closely to photos I can find of Paladins online. I proceeded to find a couple more trilo tail fragments. One was clearly just a small piece, so I left it. Another might have more of the trilo embedded in the rock, so I brought it home. It's tiny. My next significant find was the biggest blastoid I've ever seen. It outclasses my previous biggest by 1/4" in width. As you can see, the part showing out of the rock is an inch wide point-to-point. The rock it is embedded in is a bit thin, so it's possible that it's crushed/squashed out flat and wide, but the exposed portion doesn't show any breakage. It may also just have the back side broken off. I didn't find anything else real exciting. I picked up some more of the dime sized blastoids, I just can't help myself. (I'm also thinking of sending them in to my son's kindergarten class.) I also picked up a few 3d brachiopods, which you don't see a lot of at Sulphur. I did see where someone else had slid down the slope from the shale layer...quite a ways. The Sulphur site is not for the faint of heart.
  18. I've heard a lot about all of the fossil sites in eastern Indiana near Kentucky and Ohio. I've made one trip out there that I already talked about here with moderate success but it's just a little too far for a weekend trip. I'm asking if there's anything on the western side of the state near the Illinois border.
  19. This past Sunday I finally made my way down to Fowler Park, a county park located just south of Terre Haute, Indiana. I had found about it from some older posts on this site and had been trying to find time to get down there this whole summer. Fowler Park is a Vigo County Park created in the late 1960s from a portion of the Chieftain No.20 strip mine, and offers camping, hiking, fishing and, although not well-advertised, the chance to hunt for fossils exposed on the surface. This locality produces ironstone concretions from the Pennsylvanian Shelburn Formation, known to contain fossils similar to the flora-heavy Braidwood biota of Mazon Creek. Unfortunately, the days of fossil collecting at this site may be numbered. I spoke to a county park official on the phone before the trip and she said that proposals to close the park to collecting had come up at recent board meetings. She mentioned that there were concerns about over-collecting at the park. Another potential reason is that the portion of the park where most of the fossils are found, the 300 acre Wilderness Park, is in the process of being converted to the Griffin Bike Park https://griffinbikepark.com , with all kinds of specialized mountain bike trails. I don't mountain bike, but it looks extremely ambitious and well-designed, and I'm sure it will be very popular. However, speeding bikes and fossil collectors with their nose to the ground seems like it might be a dangerous combination, and clearly the bike park is going to be the primary function going forward. All that being said, now is an excellent time to go if you are interested in collecting! The construction of the trails has exposed lots of sediment by the parking area, and despite the concerns about over-collecting there was no shortage of nodules to be found even with a short walk. The Bike Park is scheduled for a grand opening in mid-October, although cyclists are already using it. Here is the informative sign at the entrance.
  20. I am hoping that someone can identify this Crinoid from crawfordsville for me. I have a book on crinoids from crawfordsville. It I don't really see anything matching mine. Thanks in advance

  22. The Indiana State Museum has an impressive collection of Hoosier fossils, a lot of crinoids as one would expect, and it is worth your time if you are in Indianapolis. The museum is downtown and very pleasant, with other museums and restaurants nearby. I wrote a blog entry about it that includes photos: http://www.americangeode.com/blog/fossil-collection-indiana-state-museum/
  23. This report is of my first trip into the St. Paul, IN quarry and my first time to collect (extensively) from the Waldron Shale. Previously I have collected the Waldron Shale at the Tunnel Mill site a little farther south but that is not very easy to collect from and the exposure is not as extensive as at the St. Paul Quarry. It was a 9 1/2 hour drive from my house near Philadelphia, PA to Greensburg, IN where I was staying so I had driven out the day before the quarry was to open. I stopped at the St. Leon (South Gate Hill) roadcut, as I got into Indiana, and did have some luck finding some small roller Flexicalymene trilobites. "This is a good sign" I told myself! The morning dawned when my alarm went off around 6am. The Quarry would start letting people in around 7:30 so I wanted to be there early to avoid any crowds or lines. Also, collectors were only allowed in the quarry until noon and I was going to make the most of my time! I arrived at the scale house around 6:45 and there was one car already waiting near the entrance. Before long a few more showed up and then a couple of Quarry employees opened the gate. After signing in, I was in the first group of cars to drive into the quarry. After a quick orientation and explanation of where we could and could not collect, there were four possible areas, we set off towards an area that had experienced some extensive weathering. As I had never collected this quarry before I was not sure what to expect so I wanted to look through rock that was weathered and maybe had some loose fossils. We got to the area after a short drive, it was at the top of the quarry and overlooked the pit itself. We were allowed to collect along the berm edge but we could not climb on or over the berm itself. It was for our safety and seemed reasonable as there was quite a lot of rock to look at along the base of the berm and the ground. The rock was already broken up and had been removed as a byproduct of the quarry operations. They wanted the limestone, not the softer shale.
  24. Last week I made my third annual pilgrimage back to the Chicago area to visit family, do a little fossil hunting, gorge myself on great ethnic foods and treat myself to some Chicago-style deep-dish stuffed pizza for my birthday--yum! I had hoped to pick up some more Pit 2 (Braidwood Biota) Mazon Creek nodules from Fossil Rock campground in Wilmington but sadly it is now closed and up for auction with the distinct possibility that it will never again allow fossil hunters to gather nodules from the spoil piles at the back of the campground. Instead, I figured on focusing back on the Pit 11 (Essex Biota) nodules in the Mazonia/Braidwood State Fish and Wildlife Area where I first had hunted nodules since learning about them several years ago. I had hoped on meeting up with some TFF members but unfortunately this turned out to be a busy weekend for them and we never managed to get out for a group nodule hunt. I did make it out to Mazonia/Braidwood for a couple hours of the weekend. Luckily, this location in Braceville is only a short 45 minute drive from where we were staying so it is quite convenient to pop over there. The weather report did not look good for Saturday afternoon and soon after we arrived the low clouds and mist turned to drizzle and then to rain and we were chased out with little to show for our efforts. We did a little better on Sunday and I have a small cache of nodules soaking in a bucket at the moment before their first freeze/thaw cycle on a shelf in my freezer. I had suggested to the TFF members in the greater Chicagoland area (including far western cities and extending into Wisconsin) that if there were other fossil hunting opportunities in the area that I might be able to replace Fossil Rock campground with some other novel (to me and my wife, anyway) location. Rob Russell suggested a small road cut in north central Illinois as a possibility but stated that a much more certain location would be the St. Leon roadcut in southeastern Indiana. We considered how we wanted to plan our week in Chicago and decided that Friday would be the best day for a roadtrip to Indiana. Google Maps (for some unknown reason) showed this trip as just under 4 hours. I figured that would be only an hour more than we normally drive to get to the Peace River here in Florida and that we could do it as a day trip. We got up early on Friday (easy to get out of bed with the prospect of fossil hunting ahead) and were on the road before 6am. Being reasonably close to the Summer Solstice and at a much more northerly than our normal South Florida latitude, the days were long and we were able to depart in daylight. We ducked under the southern tip of Lake Michigan and once in Indiana headed southeast on I-65 toward Indianapolis. Right away I could see that the Google Maps estimate of arrival time was optimistic. Large swaths of I-65 were under construction and there seemed to be as many large semi trucks on the road as cars. We stopped off along the way for a quick breakfast and continued to make steady progress toward Indianapolis. We had planned on stopping there because in my haste to pack for the Chicago trip I had forgotten to pack a long sleeve shirt. I have had more than my fair share of solar radiation as a kid spending my days shirtless and shoeless running around the country roads of northern Wisconsin with the local kids during my youth and now prefer to spend my time in South Florida covered up from the sun as much as possible. Rather than lathering up armfuls of sunblock I tend to prefer long sleeve shirts for their abrasion protection as much as their SPF. I set the GPS for the address of a Target store in Indianapolis as we had left the Chicagoland area before they were open. Unfortunately, we got the E or W prefix wrong on the street address and ended up some 16 miles away from the store. We managed to find a discount store in the area and after about 5 minutes of shopping (twice my normal preferred extent) I came away with my new "in the field" shirt for the extravagant price of $2.50. Back on the highway again and heading toward the town of St. Leon. We were making reasonable time (as best we could with the traffic and construction) but realized that 4 hours was a hopelessly unrealistic travel time. When I double-checked the distance I realized that it was around 280 miles and a 70 mph average speed would be needed to make this journey in the specified time. As that was the limit on the fastest parts of the highway we would not be arriving mid-morning as I'd originally planned. In the end we arrived for an early lunch in St. Leon where we (surprisingly) found vegetarian food at a restaurant called Skyline Chili. Chili they had--several large cauldrons of it bubbling away in the open kitchen area--but skyline? The only skyline visible in this open rural area was that shown in silhouette on their sign. Post lunch we headed north on Old State 1 till we saw the splendor of the extensive roadcut that I'd seen in Google Maps satellite imagery or in the trip photos of other groups that have hunted here before us. This roadcut through the 450 million year old Upper Ordovician deposits seems to have been an effort to minimize the slope of the highway running through its middle. We parked well off the road on the extensive shoulder near the drainage area and could hear the frequent trucks and cars go by. On their way up the incline we could hear the trucks shifting into low gear to climb the grade and the engine breaking of the trucks making the opposite trip. We were the only ones there, the sun was shining, the weather was pleasant and within minutes of parking the car we saw that the rocks around us were virtually carpeted with brachiopods and other fossils--it was going to be a good day. It had taken us 6 hours to get here (50% longer than originally estimated) but with the prospect of a new and exciting hunting opportunity, we couldn't be happier. For those who have not yet seen the roadcut at St. Leon here is what it looks like looking down the sloping highway with terraced slopes flanking the road. You'll notice the wide shoulder and the shallow drainage trough which make for safe parking well away from the traffic. The photo of the brachiopod slab right next to where we parked the car indicated a productive day was ahead of us.
  25. With the rain earlier this week and the sunny, clear, and cool weather yesterday, I decided to take off a day from work and go rock hunting. I decided to head to the Sulphur, IN road cut. A few days before, I reviewed the paper linked from the Falls of the Ohio web page. I had been to Sulphur once before, so I had a small collection of blastoids, some small brachiopods, and some crinoid stems. After rereading the paper, I really wanted to find some of the less common fossils at this site: a shark tooth and a trilobite. Secondary goal was to find a crinoid stem and calyx on a plate. I arrived a little after 10am. Pulled on my jacket, backpack, and hat and climbed up the rocks to the shale layer. Found some little blastoids, bits and pieces of crinoids. Then, to my amazement, I found this: Can you guys confirm that this is a trilobite piece? I've only found them at St. Leon before, and this looks different from those. I carefully deposited that in my tacklebox and moved on. Just a few minutes later, I found my largest blastoid (the one on the left): I kept hunting the shale layer, then moved up and investigated the upper limestone a bit, but it was not productive. Took a break, ate a Clif bar, drank some water, and walked around the bend to hunt the other end of the road cut. Eventually the shale layer reappeared and I found some more small blastoids and a small plate with a crinoid stem and crumbled calyx. I stuffed the plate in my backpack, hence no photo yet. Kept hunting the shale and something weird caught my eye. At first glance, I thought it was a large bryozoan, but for some reason it was very black. I picked it up for a closer look, that looks like a...holy cow!! I found a Mississippian shark tooth!!! Best I can tell, this is Petalodus? I was already tired and hungry, and now I was scared my tacklebox would get dumped accidentally, so I called it a day. I was am really happy with the tooth and what I think is a trilo piece. Both uncommon fossils for this site. I never thought I would actually find a Mississippian shark tooth. Especially one that appears to be complete, no breakage. Is it safe to say that Petalodus is a fairly uncommon fossil? I only saw 4 listed on Ebay and a small number on private seller sites. Not interested in selling, just trying to assess how common/rare it is.
