A Quick Visit To A Couple Road Cuts Near Oglesby, Illinois (Part 2)
Nimravis posted a topic in Fossil Hunting Trips
Today I decided to drive about 150 miles round trip to go to an auction that sometimes has fossils. This time there was only a Riker mount of composite Spinosaurus teeth and a huge ammonite that hardly fit into a banana box. I believe that the ammonite might have come from Texas and it looked like it weighed +120 lbs. Neither of these items sparked my interest, and since it was a sunny, 55 degree day, I decided to stop at a couple road cuts that I had visited earlier in the year. The first road cut (Site 1) is near Oglesby, Illinois and is located right next to the former Lonestar Quarry, that contains limestone from the Pennsylvanian Bond and Mattoon formations. The second (site 2) is about 5 minutes away and appears to contain the same type of fossils, just in better shape, since I have yet to find any loose fossils here. On my way back home I drove by Site 1 again and met Fossil Forum member @Siwash and his family collecting.

A Quick Visit To A Couple Road Cuts Near Oglesby, Illinois
Nimravis posted a topic in Fossil Hunting Trips
I was bored this morning so I decided to take a quick 70 mile drive to an area close to the Illinois State Park- Starved Rock. The road cuts are not to far from the former Lonestar Quarry in Oglesby that contains limestone from the Pennsylvanian Bond and Mattoon formations. When this quarry was accessible, brachiopods, nautiloids, ammonoids, crinoid (stems / cups), bryozoans, horn coral, trilobite pieces and shark teeth. At the road cuts, I was hoping for some of the same. (If you see that I identified something incorrectly, please advise). My first stop was along Route 71. I was able to collect on both sides of the road. The most abundant fossil that I found was the brachiopod "Composita argentia". If I was in the quarry, I could literally pick of hundreds of these in no time at all, but at this road cut I found about 20. I also found a couple of what I believe to be the brachiopod "Juresania nebrascensis". 1 piece of horn coral "Lophophillidum proliferum". 1 brachiopod which I believe to be "Punctospirifer kentuckyensis". A couple small crinoid stems and 1 small crinoid hash plate, which was not worth the taking, but I did. The second road cut was about 5 minutes down the road on Route 62. Unlike the first site, this area is very unstable and caution needs to be the first thing that you practice here; I would not suggest this are for smaller kids and people who are not sure-footed as the approach is steep, littered with loose rocks and the head wall is not secure. The matrix at this location appeared to be different and I did not find 1 of the common "Composita argentia". The most common at this site was the brachiopod that I believe to be "Juresania nebrascensis". A couple brachiopods that I believe are "Linoproductus cora". A few Spirifer brachiopods. And laslty- a couple crinoid stems. It was not a great haul and I do not think that I will be visiting either site again, but is was a great weather and what else is better than fossil collecting. Hope you enjoyed this report and again, please correct any mistakes that I most likely made.

Brachiopods- Mississippian Period -Composita subquadrata.JPG
Dpaul7 posted a gallery image in Member Collections
From the album: MY FOSSIL Collection - Dpaul7
Brachiopods - Composita subquadrata Chesterian Zone of the Bangor Limestone Formation in northern Alabama Mississippian Period (ca 325,000,000 yrs old) Composita is a brachiopod genus that lived from the Late Devonian to the Late Permian. Composita had a smooth shell with a more or less distinct fold and sulcus and a round opening for the pedicle on the pedicle valve. Composita is included in the family Athyrididae (Order Athyridida) and placed in the subfamily Spirigerellinae. The Rhynchonellata is a class of Lower Cambrian to Recent articulate brachiopods that combines orders from within the Rhynchonelliformea (Articulata revised) with well developed pedicle attachment. Shell forms vary from those with wide hinge lines to beaked forms with virtually no hinge line and from generally smooth to strongly plicate. Most all are biconvex. Lophophores vary and include both looped and spiraled forms. Although morphologically distinct, included orders follow a consistent phylogenetic sequence.

My beautiful wife scheduled a three night stay at a cabin in a Thousand Trails campground near Lake Texoma. We were to arrive on Sunday and check out on Wednesday. So, I figured that, since I hadn't been fossil hunting in months, I would schedule a trip to central Texas to follow the Texoma trip. I set up a rendezvous point in Fairfield, Texas to meet my dad on that Wednesday, and head off toward Brownwood and Cisco, Texas. I figured that the fossil hunt would begin then. But that's not quite how things played out... My two oldest daughters and I met my wife and youngest daughter in Salado, Texas on Saturday, October 14th. They had left the previous morning to spend a day with my mother-in-law in Waco and Salado. We spent Saturday night in Salado and then parted ways with my mother-in-law on Sunday morning and headed toward Lake Texoma. As we drove through Waco, my wife asked if we wanted to take a detour. She had never been to Dinosaur Valley State Park in Glen Rose, Texas, and she thought the girls would enjoy seeing the dinosaur tracks in the Paluxy River. I got really excited. I hadn't been there since I was a kid, and at that time, the river was high and the tracks were not visible. So we adjusted our GPS to take us to Glen Rose. We pulled in and stopped off to get a map of the park. We then drove straight to the spot where Roland T. Bird made his first discovery. It was amazing. The water was low and gave us a clear view of the trackways in the river. Above you can see both the sauropod and theropod tracks, They are a little obscured by mud, but they are still very visible. We left the R.T. Bird site and went to another place called the Ballroom Track Site, where so many tracks go in so many directions, it was like the theropods were dancing. It was in slightly deeper water, but it was still beautiful! The rippling water was crystal clear and the girls couldn't help but get into the water, even as a cool front brought chilly winds down the river valley. My wife loved it. She told me that Dinosaur Valley State Park was our next camping destination. Before we left, we stopped off by the iconic Tyrannosaurus Rex and Apatosaurus models built for the 1964-65 World's Fair in New York. They were permanently installed at Dinosaur Valley in 1970 at the park's dedication. We left Dinosaur Valley and drove the rest of the way to our cabin at Lake Texoma, arriving just after dark. We settled in and tried to decide what we wanted to do the next day. It was Monday, and we figured there had to be something for the girls to do nearby. We quickly discovered that our options were limited. It had turned too cold for the pool at the campgrounds. The putt-putt at the campground was okay, but the girls quickly tired of it. And most of the other recreational equipment was not well kept, or available. So, we decided to leave the campground to find something for the girls to do. I had mentioned that I would like to check out the Permian site at Waurika, Oklahoma. It was only two hours away, and this was the closest I had ever been to the site. My wife was a bit miffed by the lack of things for the girls to do, so she said "Let's go." I jumped at the chance. I had done no research on the site, other than what I had read about it on TFF. I wish I had consulted the TFF experts before we left, because I had no idea of the best places to look. We focused mainly on the sandy floor and reddish rocks, and found nothing. When we returned to the cabin, I asked where we should have looked. Jesuslover340 informed me that the gray colored exposures were the places to find the best material. So, we came away empty handed, with only one major discovery. My wife wouldn't let me take it home, though... Continued in next post...

This is probably a rookie question, so I ask for your indulgence. I have several thousand fossils collected over 50 years. I have a couple of hundred that I keep in plastic storage boxes in the house (crinoid stems and segments, bivalves, some horn coral and other corals, the one trilobite that I purchased that is probably a fake). But the rest are outside in a rock garden in the backyard. We're talking about a lot of fossils. The first question is: When you have so many fossils, what do you do with them all? And secondly, I have many fossils found in clay (see images). Will the elements have any negative effect on them? I live in Michigan, so we get lots of rain, snow and freezing temperatures.

After making a stop at the Anna Roadcut, I drove about 15 minutes to Vienna, Illinois where there is a roadcut at the entrance to Interstate 24. This rock is supposed to Be Mississippian Menard Limestone. At this location I also found some nice hash plates, my biggest blastoid of the day, Horn coral, Archimedes’ screw, bryozoan and brachiopods.

Hello all, Another small project completed for our seemingly never ending study of the Lower Permian Fort Apache Limestone east of Payson Arizona. This week, we have put together all the images and data from the hordes of productids (with spines) and one teensy brach found in the acid fines. Brachiopods are a minor faunal element in the Fort Apache Limestones, nearly 100% were found as Productids and their hordes of tiny spines. Only ONE other brach was found, and it was microscopic in size at a size of 1 mm. No doubt the large amount of mud and silt raining down on the bottom of the Fort Apache Sea made life very difficult for any type of filter feeders. Largely missing as well are corals, crinoids and sponges which also feed by filtering the muddy waters. Only the Productids seemed to be adapted to such conditions. Both silicified and calcified fossils were found. Some of the silicified fossils were very delicate and had many of the spines still attached when dissolved out of the limestones with muriatic acid. Winters in his monumental GSA memoir 89 identifies the productids as Bellaclathrus spinosus, and the tiny brach as Pseudodielasma sp. Since this is a very generic looking brachiopod, well go with his identification. Pseudodielasma sp. top view, pedical valve. This brach is the size of a pinhead and is the only one found after processing over 200 pounds in limestones! 45x Pseudodielasma sp. bottom view, brachial valve. Here you can see the opening at the top for the pedicle to emerge for external support on a hard substrate. 45x Bellaclathrus spinosus, only about an inch across it is far smaller than the average size of the productids found in the overlying Permian Kaibab formation. This one is calcified on the surface of the limestone found by cracking open large rocks. 2x Bellaclathrus spinosus - very flat upper valve that is calcified. 3x Bellaclathrus spinosus - Silicified specimens show much external detail. But they are hollow and very delicate! Notice the spine coming off the wings. 2x Bellaclathrus spinosus - We found hordes of loose productid spines in the limestones. 7x Bellaclathrus spinosus - Close up at 20x of some of the spines. Most are hollow tubes, and never come to a point. In life they are filled with live tissue and the spines grow by adding on to the ends. Bellaclathrus spinosus - Two spines on a common base which was once the outermost layers in the productid shell. 20x. Well, thats it for this week. Hope you enjoyed our little presentation!

My recent trip to the Fort Payne has me wondering how big do brachiopods get? So why not a thread to show off the largest ones we've found! Here's some of my monsters... First up Productus sp. from the Fort Payne, Lower Mississippain. I think this is Syringothyris sp. from the same formation as the other. I believe this is Rhipidomella sp. (same formation.) Lets see yours!

Hi all, During the Fossil Fair of Ede in March 2017, some of you might recall that I bought a big box full of different fossils. Well, here are some of them. Some spiriferid brachiopods (Punctospirifer kentuckyensis) from Breckenridge, TX, USA; from the Pennsylvanian of the Carboniferous. Collected in 1969! Now, as there are quite a few, I already gave a few, and will give a few more, away in trades with fellow forum members. Now, even though this is a nice amount of info, when I search up "fossils breckenridge Texas", I don't get any relevant results supplying more info on the location... So, anyone know more about this place? Thanks in advance, Max

10 SW Ohio Ordivician mini-collections to trade
hrguy54 posted a topic in Member-to-Member Fossil Trades
I would like to expand my overall collection. I have collected a ton of SW Ohio Ordivician fossils over the years. I believe that most non-Ohio collectors are unaware of how great this area is for collecting. I'd like to get other specimens from other areas. I have 10 "mini-collections" (samplers?) made up of typical SW Ohio fossils, minus the trilobites (they aren't really so widespread). The collections (similar to that pictured below) will include 2 horn corals (one with beekite), a gastropod, a cephalopod, the top valve of a rafinesquina, and 6 complete brachiopods...a hebertella, a vindlandostrophia ponderosa, 3 different kinds of lepidocyclus, and one of the following... a glyptorthis, a plaesiomys, or a retrorsirostra (I say one of these three because I struggle to tell them apart). I would like to trade to different people from different areas other than SW Ohio/No KY/E Ind. Or from the Devonian in NE OH and around Penn-Dixie...I'm pretty good on those already. All pieces will be in very good condition, prepped and ready to go. I would like the same in return. Just because I'm offering 11 pieces doesn't mean I want 11 from you....I want a good quality representation of what is commonly found in your area...we can discuss/negotiate it. Of course, send a photo. If you want to suggest other trades/sales I'll listen. Right now I will not consider overseas shipping. PM me if interested. -
Recently I was for one week in the Ardennes in Belgium. There I visited different locations where you can find fossils. For example I was in Barvaux and found many brachiopods: http://www.thefossilforum.com/index.php?/topic/77098-mainly-brachiopods-from-barvaux/. I also visited the old Lesse quarry near Resteigne, where you can many different fossils. For instance I found many brachiopods, corals and also some trilobite parts ! The layers belong to the Eifelium, Middle Devon. Too bad that the weather was not that good but I am nonetheless satisfied with my fiends: Here are some pictures of the quarry: Its an old quarry and the nature reclaims the area more and more. So you also see some nice animals ! Now too my finds: Firstly some brachiopods: They are indeed very common there so I found many. Those brachiopods are all Sieberella sp. or? Here a detailed picture of one (3 cm long): And this should be a Spinatrypa sp. or?

Last year Kevin H. gave me some information about a good location for fossils near Barvaux (Thanks @Kevin H. ) Its a construction site where you can find many devonian fossils. The most common fossils are brachiopods but you can also find corals and gastropods ! Too bad that it seems that they not work there anymore ... despite of that you can still find many brachiopods. Firstly some pictures of the site: And there they are ! Its a pity that they are often damaged ! I spent there about 3 hours and found more than 300 brachiopods ! I think more or less all are Cyrtospirifer verneuili ... And here are the biggest ones: The biggest one is about 8 cm long and very massive. Its difficult to find such big ones in a good condition ! This one is a very nice one becuase of the good preservation. Its about 4.5 cm long. Some more brachiopods from other angles: + These three brachiopods look a bit different ... can somebody determine them? I found also some brachiopods where you can see the spiral shaped lophophores ("skeleton") of them... I can post brachiopods the whole day But I also found some corals

Back at the end of 2015 I posted about an Early Christmas present...went hunting on a ridiculously warm Christmas Eve at a roadcut near an exit on I75 between Dayton and Cincinnati. Found some Flexiycalymene trilobites, RafInesquinas, and Cephalopods - Orthocones. That spring I went to the other side of the highway and found some more of the same plus these trilobites: I then decided that I would visit each of the roadcuts between the I675 and the I275 interchanges. This has taken me until this past May...about a year. The one closest to Dayton was pretty disappointing. I picked up a few nice Strophemans, a RafInesquina, a partial Leptaena, and a few brachs (right of the coin below) I was unable to identify...there were a ton of those. I went back to the initial interchange but went to the exits at the south end. Google maps said it was about 70 feet lower than the north exit ramps I was not expecting what I found.... It was a Vinlandstrophia Ponderosa mecca. Both sides of the highway as it turned out. Here are some from one side. The other side had nearly as many. Some broken and showing nice geode centers Along with a nice array of Orthocones, RafInesquinas, Gastropods and even a few Horn Corals. I've never found horn corals along side the Vinlandstrophia Ponderosas. The next stop, slowly getting closer to Northern Cincinnati, was a very exciting spot not only Cephalopods and RafInesquinas but some unexpected Flexicalymene trilobites: Including the largest "roller" I've ever found (2 views)...As big as a quarter. I had to prep it as soon as I got home. As I got to the last roadcut before I275 I didn't know what to expect. No 2 consecutive were the same. Even the same exit was different at north and south.
