  1. 2 things

    First off, I suffered a leg injury while duck hunting and I almost died. No, I was not shot by another hunter, I slipped and fell in freezing cold water. I am just letting you all know I am okay. Second, I need an honest opinion on this fossil I decided to hang on the wall. Does it look good in the frame? Should I add anything else to the label? Any ideas will be appreciated.
  2. Fossil Bone or just rock?

    Hi again-any ideas on this one? Found loose on the ground in Wyoming. Think its fossil material or just rock? thanks for your time
  3. Fossil identification

    I found this palm sized fossil in a river in riverton Wyoming and would like to know if anyone knows what it could be
  4. Possible jaw bone

    I purchased two bones from a seller in Wyoming about 10 years ago and cannot figure out what animal they are from. It's about 3 inches. Can anyone help? Bone #1 is pictured below:
  5. An Eocene summer

    It was a busy summer, and now it is snowing. I got out a few times this summer and here is my report for y'all's enjoyment. Most of my outings were into Wyoming's early Eocene. Way back in the spring I went to a newly discovered mammal site. I showed one jaw here: Here is a view of the site. This is the early Eocene Wind River Fm in central WY. (Wasathcian in age). Lots of land to look at out here, and I have only prospected a wee bit of it. My pack is down thereon the flats... let's see if we can find any fossils down there. OH, look... a mammal jaw. And can you find an additional bonus tooth in there? Right next to this there were a group of crocodile bones. Again... find the bones. I dug around quite a bit to try to find the source of these bones and got totally skunked. I usually get out into the Eocene beds of southwest WY on Labor day, but this year it happened a month late, so here are some pix from the first weekend of October. It starts getting cold at this time of year. The first photo is me at an abandoned oil well site where the oil folks had scraped up a limestone layer in their bulldozing. The layer has bones in it... mostly turtle pieces and lots of very small (and practically un-prepable) fish bones. If you break rocks long enough you will find good stuff. Below are a the best things I found on this visit. For those interested, these things are prepped with ye ole air abrasive under the microscope. Dolomite at about 20 psi. There is potential for the air abrasive to abrade the bones and I am not sure if these teeth got overly air abraded or are suffering form Eocene erosion. It is very slow prep, so I don't focus too much on this layer. First a little croc dentary. Note that the bone runs off the edge of the rock. I spent a long time looking for the rock that contains the rest of this jaw... again, skunked. But this is a good little find. The empty roundish area to the right of the jaw is the impression of a snail. fresh water snails of the genus Physa are the most common fossils. This next bone is the angular bone of a small croc. The angular is one of the bones in the lower jaw. The limestone layer is in the Wasatch Formation. After busting up enough rocks, I went to one of my favorite sites about a half mile away. Also in the Wasatch Fm. This layer sits just above the same limestone layer that I collected at the oil well site. Here I am digging. Note the weather is getting nicer; I have jettisoned the coat. This site is full of small randomly distributed fossils. Again, mostly turtle pieces, but also some good croc material and occasional mammal teeth and jaws. And here is a distant view of the quarry. The limestone with bones is seen as an small cliff just below my backpack. So, let's look at a few fossils. First an emerging soft shelled turtle piece ( a costal plate). That is a dental pick for scale. The digging here is best done slowly so you don't break the bones. You can see other pieces of bones in here. The first photo in the next post is the same turtle piece fully exposed.
  6. Learned something.

    Hello everyone! So, a bit of a long story. I have a habit of looking at my fossils under a magnifier. Today, I was looking at a knightia fossil and I decided to theorize a little bit about it after looking at it. After looking at it for a little bit, I told myself that it looks like a sardine. After I did that, I went on the internet to take a look at the family of knightia as well as a family of herrings and sardines. to my surprise, my theory was correct. Knightia and herrings and sardines share the family clupeidae. You learn something new everyday! Jared
  7. Tiny Fossil

    Hello, I was organizing my fossils I got in Kemmerer, Wyoming, today. I stopped to look at a small Phareodus fossil I had. I noticed something I never noticed before. I took the fossil and put the odd thing I noticed under a magnifier. Picture it attached. I am not going to lie, it is TINY. It has ridges one one side as well as 7 lines coming from the dark part. Any idea what it is? Could it be a plant, or part of a fish? Jared
  8. Possible WY Jurassic Fossils?

    I was hoping someone would recognize this odd assortment of shapes and point me toward a reference. The were all collected from the same road cut on Highway 89 not to far from Smoot, Wyoming. The paper in the picture is 8.5X11 inches (roughly 20X30cm). They are notable because they are large pieces in a matrix that a least on the surface fragments into small pieces. There were alot of curved pieces that are about an inch thick with a very regular curvature like broken pieces of ceramic pipe. Thanks!
  9. Hi friends, I'm trying to learn more about Green River fish. Interested to know if anyone sees anything wrong with this fossil (repair, restoration, coloring/painting, composite). The color seems slightly darker to me than the typical Green River fish that I've seen but it's not dark enough for the 18 inch layer fish that I've seen.... so that's part of why I'm curious/asking. Thank your for your insights.
  10. Good evening, today was THE day for me. In our city was the annual fair with fossils on offer. I was out and looking for uncommon/rare dino teeth and was lucky to find some. I know that most of the ID done by the sellers is wrong I would like to show my new aqusitions to you throughout the next days and hope for your help. No. 1 was sold as an "Richardoestesia gilmorei" from the Hell Creek Formation, Wyoming, USA (unfortunately no county provided). Length: 18mm Width (base) 6mm denticle count: Side 1: 6 per 1mm Side 2: 7 per 1 mm, (ca. 38 per 5 mm) I had to call it side 1 and side 2 because honestly I was not able to figure out which side is the mesial and distal side... Thank you very much for your help!
  11. Rugose or Bryozoan?

    Is this a rugose coral or a bryozoan? There are definite bryozoans in this rock of different types. I was thinking it's a rugose coral, but want other eyes on this specimen. Collected from the Phosphoria Formation in Wyoming, so it's Permian in age.
  12. What do y'all think these are? They're bits of debris from a slide I was working on. All I can really tell you is that they were photographed at 40X magnification, scale bar 50 microns. This set of slides is across the Paleocene to Eocene, but I unfortunately don't know what rock this single slide sample is from. Sample is from the Hanna Basin in Wyoming.
  13. Hi there, i found this tooth on an European auction site and was wondering whether the ID is correct and the quality of the tooth is acceptable. Now I am considering of buying it... Unfortunately there are no better pictures available. According to the rules I have edited them to hide any hints on the auction site. The tooth is labeled as „Edmontosaurus regalis“, the origin is: „Dog Bille quarry, Lusk, Wyoming“. Thanks in advance for your help!
  14. This baculite piece appears to have undergone replacement by chalcedony. The walls of the empty chambers are very thin and delicate. There is a bit of original nacre intact. Thunder Basin area of NE Wyoming.
  15. Fish story for the ages: High schooler unearths rare fossil by University of Chicago, September 30, 2019 https://news.uchicago.edu/story/fish-story-ages-high-schooler-unearths-rare-fossil https://phys.org/news/2019-09-fish-story-ages-high-schooler.html Yours, Paul H.
  16. Barely a month had gone by since my last trip to New Mexico and Colorado, but I already had plans for this trip in the works. Primary focus this time, which was a solo trip, was fossil collecting, visiting well known sites that have been on my radar for quite some time. I flew out to Salt Lake City and drove directly to Kemmerer, WY. My first stop there was Fossil Butte National Monument: Here is a view of the visitors center (free admission) and the surrounding barren, but awesome landscape that surrounds it:
  17. Hell Creek Metatarsal Joint Fragment

    Hey everyone, I recently came across this fossil online. It was listed as a metatarsal joint fragment, which to me checks out, but the person further identified it as a Dromaeosaurid [though they didn't specify based on what characters] and tentatively assigned it to Dakotaraptor based on size. Now I was wondering: Can remains this fragmental even be reliably distinguished from the other small- to medium-sized theropods in Hell Creek? The fossil was found in Hell Creek deposits in Wyoming [no info on the exact location], measures 30.9 x 27.5mm [not specified along which sides], and weighs 252 grams. Thank you for any input on this!
  18. Fish dentary?

    This was collected off of WY11, between Laramie and Centennial in Albany County, WY. Definitely limestone. It was thinly bedded, with an upper layer that's full of shelly material. There were numerous calcite veins in the rock also. This piece came from below that. I found bits and pieces of other fossil material, including some other bits that look similar, like part of a jaw. I didn't have much time to spend, so really, finding this was entirely luck and I didn't get to look for more. I'm inclined to think Forelle Limestone currently from what research I've done. I believe that limestone is upper Permian. Other units that outcrop in the area along this highway range from Pennsylvanian to Cretaceous. I'm struggling to find a geologic map with enough resolution to really tell me exactly what I'm looking for. I'm still looking for a map of the county that's not a historical map from the University of Wyoming. The forum is often pretty knowledgable though, so input is appreciated. I know there's not a whole lot of it preserved. I think it was exposed in a wash for a while so not a lot of bone is left. Not sure if there's enough left to identify. I'm not that well versed in vertebrates. I can get better pictures tomorrow. My phone camera was really struggling to focus tonight. Any ideas? Am I right in labeling it a dentary? Or is it something else entirely?
  19. Ricky’s Field Museum prep

    Hey everybody! I realized I never made a thread for my internship at the Field Museum in Chicago this summer. I interned as a fossil preparator under Akiko Shinya in the McDonald’s Fossil Preparation Laboratory (that’s the “fish bowl” lab on the second floor right next to Evolving Planet with the big window). There were some amazing things being prepared in the lab - an Antarctic Lystrosaurus, lots of Dicynodonts, Green River fish (some massive Phareodus), Sauropod femurs and ribs, a massive slab containing several sturgeon and paddlefish - but I’m not sure if I am allowed to post pictures of them, so for the sake of confidentiality I won’t just in case. This is the lab, and I always sat in the red chair, right up next to the window. One of my favorite parts of this internship was seeing all the little kids so excited about what we were doing in there and interacting with them. I was preparing a Priscacara serrata (specimen PF 16961) from the Green River formation of Wyoming, Eocene (~52 mya). All I used was a pin vise and an Amscope stereoscope. This fish also seemed to have slightly “exploded” from the pressure of fossilization as well, it’s jaw was crooked and head smashed, thought most fins seemed surprisingly well intact. The prep took 199.5 hours to complete, from May to August. I finished the prep on the final day of my internship, staying late after the museum had closed to the public and all the others in the lab had gone home. But it was far worth it, because "your name will forever be associated with this specimen." -Akiko Shinya I took a picture at the end of every day and I made a time lapse with it to see the growth! The link is at the bottom of the post. (I kept that floating scale in front of its mouth because I thought it was kind of funny that it looked like the fish was trying to eat it!) You can watch the time lapse Here
  20. Too Many Fossils

    Hello, So, I'm going to get straight to the point. I live in a small house, and I have way too many fossils right now. My entire collection consists of 35 Diplomystus, 10 Knightia, 7 Phareodus, 2 Mioplosus, 36 pieces of petrified wood, 1 fossilized sand dollar, 2 gastropod shells, some fish bone fragments, and 38 other fossils that are unidentifiable. I'm going to be up front right now, I have way too many fossils in my small house. I'm trying to figure out what to do with the excess. Does anybody have any ideas what I could do with the excess? Any help will be appreciated, Jared
  21. 4 Different IDs

    Hello, So, I have a LOT of fossils after my trip to Kemmerer, Wyoming last week. To save time on identifying them, I sorted them by what they looked like. I have 5 piles, so 5 different species. I am posting pictures of one from each pile, so I can find out what these are. The pictures are attached. The first and second I have a LOT of, the third I only have one of, and I only have three of the fourth, (The others are not as big as the one in the picture.) The fifth I am having problems uploading. It will come later. Can someone help me ID these four? I will post the fifth when I have a chance. Jared

  23. Heading to Wyoming Sunday, advice appreciated

    Hey guys and gals. I just recently moved to Ft. Collins, and I will be taking a month long fossil hunting/sight seeing excursion starting Sunday. I believe we will start off in Wyoming and head for Yellowstone, then head south to other national parks and the Grand Canyon. I plan on stopping at Fossil Safari for some nice fossil fish, but I would also like to hunt some other areas around the state. Should I just look for road cuts? Any other spots or pointers will be appreciated. If I meet up with any of you, I can bring some Florida fossils to trade for a couple of hours in your spots! Let me know! -J
  24. Here is another update from my July 2019 solo Fossil run! (Edit...it appears some of the fossil pictures are displaying poorly....I will rectify this shortly.) PICTURE HEAVY Day 1: I drove solo from Omaha, NE to Fossil Butte National Monument. I left at 0300 local and made it to the Museum at the monument about 45 minutes before they closed at 1800 local. The museum is outstanding. Small, but amazing. Also, unlike most other national parks and monuments, it is FREE and open 7 days a week during the summer. I didn't take any photos as A, I was exhausted, and B, there are plenty of pictures of the museum already on the web. Sometimes, I like to just have memories I don't have to share. Anyway, after drooling over all of the great stuff to view (think complete two meter crocodilian skeleton), I got my second wind and had to find a place to camp before dark. Thankfully, you get about 18 hours of useful sunlight up in that area, so I set out for a "secret" campsite on the BLM land just northwest of the monument proper. I found the site and made camp. There was some promising looking shale exposed here, but not a fossil to be found. (I did bring a few samples back however as I discovered later that there was some interesting fluorescence in green, yellow, and orange on some of the rock!) I'm at around 2100 meters above sea level for the night! Either way, beat down and a bit light headed from too many years living in the flat lands, I caught a nice sunset and wolfed down four MREs. I planned to spend the next day in deep in the Green River Formation. Day 2. It was a rough night. I got about two hours sleep from a combination of exhaustion, excitement, and the strangest wind storm I have ever experienced. At right around 0000, a single gust of wind dropped the temp for around 22C to 8C in less than five minutes. I was prepared for this, however I wasn't prepared for what showed up 45 minutes later- sustained 40kph winds with 72kph gusts. Due to the hard rocky ground, I couldn't use tent stakes or bury the deadmen for my guy lines on the tent, so I spent the next three hours in a very noisy, semi-collapsed tent. As the storm continued, I realized I was going to have to set the guy lines under the tires of my truck if I hoped not to blow away. Imagine my surprise to discover that with all that wind, there was not a cloud in the sky. It was crystal clear out. What I had thought was rain hitting the tent was actually small bits of gravel! I carefully positioned the truck as a bit of a wind break and anchor for the guy lines. Ten minutes later, the windstorm quit. I made twelve cups of espresso in my trusty Moka pot and headed over to American Fossil Quarry at sunrise. I didn't bother taking pictures of the quarry as there are plenty on the web. I did a half day dig. I had a most excellent time. What follows is photos of about a third of the fossils I found. I have many many more that need prep work, but these were my "practice" specimens. I found so many fish fossils, I kept only the best ones, plus a similar amount to use as practice for preparation and preservation techniques. Sure, it is a pay-to-play quarry, but I got more than my money's worth I feel. I actually got a bit bored with finding fish, something I never thought would happen. I also found some scales and coprolites, but no stingrays or plants. One fellow digging while I was there ended up with a magnificent palm leaf however! Anyway, here are a few of the fossils I have prepped so far. Apologies for the less than perfect photos. I have only owned this macro lens for a few days and haven't quite figured it out yet. Also, you will notice that they appear shiny, this is because the fixative has not fully cured yet. I will share my best two specimens in other threads later on!
  25. Please help identify my bumps.

    I am a complete novice. I have searched for fossils as a hobby but have never found anything like this. I found this near Lovell, Wyoming, near the base of the Big Horn mountains. It measures approximately 5cm x 5cm. Thanks for any help.
