    after arriving in Utah I was itching to get out and dig. So I found a spot on google and boy did it pay off. I anyone knows what layer it is or what these are please let me know. I can’t do close up of any of the fossils tomorrow if need be.
  2. Marjum Formation Dig

    Went out on a dig near Utah for Modocia typicalis with Gene Boardman one of the site managers at U-Dig. Gene is a really nice guy. He gifted the first trilobite of the day to me (I asked if he was sure and he said he had a few more). We split a lot of rock. A lot of work for a few beautiful bugs. Each image is captioned. Some are out of order. This is the great Gene Boardman. What I admire the most besides his genuine personality and big grin, is that he's a tenacious fossil digger. He kept reminding me to check every rock and to keep splitting it down as far as it would go. Here he has a thin slab of Marjum shale but he was able to find the first trilobite of the day with this fine split method. Really nice guy. The Marjum was not easy to split. It kept fracturing in multiple spots. The overburden was very brittle so we had to get down into the good, red layers. Here we are letting the rock "sweat" as Gene calls it. That means you set your chisels in the rock and let it naturally split and come back later to open up the bench. Lots of hard work. Gene helps run the U-Dig site and is known around the area for his enthusiasm for hunting trilobites and other fossils. The first Modocia typicalis was recovered 2.5 hrs. into the dig. It's small but complete and has some decent features. This is Gene's finest Modocia typicalus in his shop. He did an excellent preparation job. This big Modocia (over an inch) probably isn't a full specimen but has some great features. This smaller Modocia popped out of the same slab as the larger one. You can see it's impression on the left side. Another of Gene's Modocias. Gene gifted this M. typicalis after our days labors. Boy was I happy!

  9. capital reef oysters II

    Hello all Here is a companion query for help. This item is flat, tapered to the top and slightly concave from the underside. The two pictures are a top view and a bottom view. It is about 2” thick. The scaliness, if there is such a word, looks like Exogyra, but does not have the curved narrow end described for Exogyra. I assumed this was a flat mollusk shell when I picked it up (E of Capital Reef, south of Rt 24, about 4 miles outside the park) but can’t find a match with the limited references I have. Help appreciated. Thanks. Tom
  10. Help to ID Trilobites fron Wheeler Formation

    Hello friends, I need your help to learn a little more, I am not an expert in trilobites, in fact what I own are the Brachiopods, but accommodating my fossils, I found myself very similar and they filled me with doubts, can you could help me distinguish between an interstricted Peronopsis and a Ptychagnostus atavis, both of the Upper Cambrian, of the Wheeler Formation, in House Range, Millard county, Utah. Thank you.
  11. capital reef utah oysters

    Hello all, I’d appreciate help with two sets of oyster fossils from Capital Reef, Utah. This post has one object, another post will have the other, due to photo size constraints. These were collected to the E of Capital Reef, in south of Rt 24, 4.2 miles outside the park, on a road heading south. From other discussion, I see references to a limited range of species found here, some posts on the Forum and other places, say they find a single species (Pycnodonte). I think I have something different.The pictures on this post are a cluster rounded oblong shapes, ranging from about 1” to somewhat larger. The picture is from the top and from the bottom. Any help appreciated. Thanks. Tom
  12. Mosasaur Teeth?

    I bought these at a Rock Shop in or near Moab Utah. Pretty sure the dude said they were from around there. What do you guys think?
  13. This spring break (March 17th-23rd) my girlfriend and I are planning a trip in Utah, Wyoming, and Colorado. It looks like most of the big dig sites are closed for the season, which was a disappointment for us to see. The tentative plan was to go through Kemmerer from Salt Lake (home,) and hit the digs sites there, go through Vernal to the Quarry and the Prehistoric Museum there, then to Dinosaur National Monument in Colorado with a possibility of hitting Price Utah and the Cleveland Lloyd Quarry on the way back. Without any of the digs open, it seems like we're just trying to find simple things to kill our time, but we'd rather be out doing more engaging fossil hunting or learning. Does anyone have recommendations for areas somewhere nearby where our travels will take us? Any suggestions for digs, museums, cool fossil shops, or even just pretty places to camp are all welcome and greatly appreciated!
  14. A cute T-rex cousin from Utah

  15. I'm trading a bunch of fossils mainly from Utah and Wyoming but some other locations as well. In return I'm looking for theropod teeth, ammonites, trilobites, crabs, gastropods, and more shark teeth or anything else that's interesting. You can reply here directly or PM me. I'll post another set some time later this week. Here is the assortment. Wyoming Knightia (Green River Formation, Eocene) Assortment of brachiopods, a crinoid holdfast in the middle, and pyritized worm burrows from Paulding Co, Ohio (Silica Shale, Devonian) Fossilized Great White tooth from Cape Town Another Great White: Knightia Elrathia kingii (Wheeler Shale Utah, Cambrian) The following Wyoming Knightia (Green River Formation, Eocene) Some are in better condition. There's a couple that haven't been completely prepared. I know some of you like to prepare your own fossils: Elrathia kingii More Paulding Ohio fossils (horned corals and brachiopods): A Phareodus scale: Another Great White: A St. Mary's formation Chesapecten conglomerate from Calvert Cliffs, MD:
  16. Here are two interesting Pennsylvanian fossils that I bought at the Flagg Gem and Mineral Show in Mesa, Arizona (~4.5 inches wide) from the Apex Mine near St. George, Utah hosted in the Callville Limestone. A Chatetes sp. sponge is coated in azurite and malachite. Syringopora sp. coral molds are in goethite with significant germanium and gallium values. The goethite replaced the limestone. See this USGS article about the mine: https://pubs.usgs.gov/bul/1577/report.pdf
  17. How I Found Fossils in the Snow

    The cabin fever I’ve had the last couple months finally drove me mad. Inspired by the posts of @KimTexan, @FranzBernhard, @Al Tahan, and @Calico Jack. I decided to brave the snow and cold and attempt a new place that I had been contemplating visiting for several months now. This was not the easiest time to be hunting and probably not the safest thing to do as I haven’t seen a lot of the fossils in the formation, the entire outcrop may be under a foot of snow, and adding snow to any fossil trip is inherently more dangerous. But I tried to insure the highest chance of success and safety and I will now share my experience with this. I don’t claim to be a professional and I don’t claim this is safe, if you attempt to hike and hunt fossils in the snow you do so at your own risk. Since, I didn’t know what exactly the fossils looked like, I had only glimpsed at a couple specimens in a couple local museums. I took to the internet for any pictures I could find. I found this thread This website http://www.ammonoid.com/Manning.html This paper https://emp.byui.edu/STRICKLAND/fossil.pdf And various examples for sale that I won’t link here. I just basically looked at anything and everything from the formation to get a sense of what the fossils looked like. To make sure I was going to the right location I looked at geologic maps via the apps I have listed here I looked land ownership maps like this one https://platmap.trustlands.utah.gov/ and this one https://blm-egis.maps.arcgis.com/apps/webappviewer/index.html?id=6f0da4c7931440a8a80bfe20eddd7550 And a couple other more site specific maps to double check. I also looked at a topographic map of the area with geologic maps overlaid https://geology.utah.gov/apps/intgeomap/index.html# Sattelite images from https://www.google.com/earth/ and roadmaps like this one https://www.google.com/maps I knew I may not have cellular reception so I brought a Garmin eTrex GPS as my field instrument along with extra batteries. I also brought a rugged Brunton compass in case my batteries all died. Some tips: Research how the area generally is during winter. Look up depths of snow in the area if available, any road closures, if available, where snow plows will plow in the event of a snow storm, take a look at the weather forecast, look up roads or trails you will use as escape routes during snow storms, etc. Having camped in the snow and have done a decent amount of winter sports like ice fishing, I know how to dress warm. Remember more layers is better. It’s better to have to remove layers than add some because you may not have any extra clothes to add. On the other hand, try not to break a sweat as that sweat will cool you down very quickly and may put you at risk of hypothermia. Make sure to bring And ALWAYS notify someone where you are going, when you are going, how long you will probably be, what you will be doing there, and if needed how you are getting there. FOR MORE TIPS refer to this handy guide by the Boy Scouts http://www.boyscouttrail.com/library/wintercampingtips.asp This article from Backpacker https://www.backpacker.com/skills/beginner/winter-camping And this article from Backcountry https://www.backcountry.com/explore/winter-camping-101-gear-tips-for-staying-warm
  18. Brachiopods or leaves?

    How’s everybody doing? I’ve got some fossils I need ID’d. They are from the Manning Canyon Shale in Utah. They are Late Mississippian/Early Pennsylvanian in age. Thanks!
  19. Permian crinoid

    Hello helpful fossiliers, Help please. These fossils came from outside Moab close to the Colorado River, but on a high shelf. The river is not visible from this location. Roadside Geology of Utah identifies this area as Permian, as did a BLM paleontologist. They are from about 10-15 miles SW from Moab. The rocks are largely a red base (clay?) with a gray-er surface. These three pictures are actually 3 different locations on the rock, but I think (wonder if) they are the same life form. The first is about 2 mm long. The ruler shows a mm scale. You can see the cross section end of the item on the fossil closest to the ruler. The second is a round disc from elsewhere on the surface and the third is a connected series of round discs. My sense is that the disc and connect discs are crinoid segments. Is the first picture also a crinoid, or am I way off on all this? I can post additional pictures if anyone asks. Thanks. Tom
  20. Gerster Fm. Productid Brachiopods

    This particular species had spines attached to the shell which is not all that common. There are four spines attached on the thumbnail brachiopod. The holes in the shells were where spines used to be attached. Found during this trip here:
  21. Acrothele subsidua

    Found associated with Elrathia kingii and Itagnostus interstricta trilobites. See field trip report here:
  22. I recently just visited the University of Utah and they have a large display of petrified wood from all over. Here are some of them. large logs by the stairs
  23. This is a continuation of my last post with @UtahFossilHunter going back to the island last minute before the snow flies. This time we tried another outcrop of the Undifferentiated Cambrian (now determined to be the Chisholm Formation) on the search for fossils. Link to Part 1  Here is the map on my last post.  This is the Chisholm Formation at the foot of the mountain.  We went up farther on the mountain and found a contact zone. Being a large dipping anticline going down the slope at an angle, the rock layers get older on the bottom then the top. Other places on the island the rock layers are rotated sideways so we kept going right and slightly down more.  We kept going up and we found some Bonneville gravel.  Further along we found lots of a good structural rock with en echelon fractures from nearby faults. But no fossils. We decided to check a few other rock layers again just in case. The Ordovician Garden City Formation had absolutely nothing. So we went back down and drove to another place where the Silurian Laketown Dolomite outcrops so we hike up and.....  We found our first Silurian fossil! We didn't expect anything to be in this formation. Unlucky for us, it was on a boulder so we thought we had to take out a chunk of it. UtahFossilHunter and I had forgot our chisels but we had our hammers. So for ten minutes we kept trying to break off the chunk it was sitting in. You can see in the pictures the fossil was on a ledge. The bedding layer below was a large chert nodule layer so every time we hit it you could hear little shards zooming by like ricocheted bullets. After that ten minutes while watching the snow clouds make their way across the Utah-Nevada border, we decided to take a risk and try popping the fossil out just underneath the shell. That risk payed off and it came out whole. The lesson here is if you know you might be looking in hard rock layers don't forget your chisels.
