  1. Green River Fish ID

    Here is a large partial fish I found a few weeks ago. Not sure, but suspecting maybe Phareodus?? Any thoughts? Thanks, Mike
  2. Hello. A while ago I purchased this specimen from a highly reputable and established seller. It's a T-Rex jaw fragment from Lance Creek, Wyoming, and was a surface find (see photos of the original specimen in situ; according to the finder, "the piece in question is at the very bottom left, on top of the edge of the longer bigger bone; the tooth grooves are face-down."). I'm reaching out to Fossil Forum for guidance along the following lines: 1) What part of the jaw is this most likely from? I've been studying images on-line at a cursory level, but I can't find the distinction convex part of the bone that my specimen has (the part that sticks out like a thin ridge). Any thoughts or, even better, photos of comparable specimens? 2) I trust the original seller, but since it was not found as part of a larger Rex specimen, I figured I'd ask for your confirmation: is this almost certainly a T-Rex? I'm fairly knowledgeable regarding teeth, but not mandibles. Thank you all very much in advance; any insight would be deeply appreciated. With best regards and gratitude, Ryan
  3. Wyoming Wonderland

    It has been 10 days since my trip to Wyoming came to a close. I have done a rough cleaning of my finds and will display some of them for you. To begin with, I had a continuing education class in Jackson. The scenery around the Tetons is truly breath taking. But I was eager to depart and begin a fossil hunting adventure with the 3 free days I had left. I love my bald eagles and found this photogenic pair as I departed town. My first stop was NE of Farson in an attempt to find some petrified palm wood. Here is the "road" which brought me to where I thought I should be. No petrified wood was found but I did put a few specimens in my bucket. I believe these are some algal structures??? They littered the butte that I was hunting on. This was not the start that I wanted, but just enjoying the openness of the Wyoming countryside made up for the lack of finds. I finished the day by taking in this sunset before departing. Tomorrow will be a new day and the fossil gods may be kinder, at least I hope. The next site is south of Wamsutter, and the hopeful finds will be "Turritella agate". This Green River Formation (Lamey Member) fresh water snail species is really Elimia tenera, not turritella. I must thank @jpc for directing me there without a hitch. This site appeared on google earth to be a hop, skip, and a jump from the gravel road. It is MANY MANY JUMPS!!! Had he not told me to continue until I saw these hills, I would have experienced my second failure. As you approach the hills, the road forks and the right fork takes you up on top giving you this view. UP top, Elimia are everywhere, for miles and miles!!! Every dark rock in this next photo' foreground contains them. An individual rock typical of what you see in the previous photo:
  4. Prepping Wyoming Finds

    Prep help needed!!!!! 1. Blue Forest petrified wood. I have used a chisel and an engraver to remove most of the algal growth on the outside of the wood. Is there a chemical means to remove the fine stuff that remains without hurting the wood or the blue agate?? 2. Individual silicified shells of the fossil snail Goniobasis (Turritella Agate) found at Wamsutter, Wyoming. Again, is there a chemical way to remove the tan coating on many of these. Even if it took the shell away, I am most interested in preserving the beautiful silicified interiors of these shells. I have tried vinegar and potassium chloride with NO success. Thanks, Mike
  5. I found this fossil in a mountain stream near Lovell, Wyoming. I was wondering what species it could be? It has a shell like some kind of clam. It also has 3 reddish brown stones in it that shimmer in the light. Could these be pearls? The rest of the fossil doesn’t have any reflective gleam in the light. I added blue arrows and circles to show where the possible pearls are at. The whole fossil is about 1 and 10/16 inch long x 1 and 1/4 inch wide x 3/4 inch in height (from the back of the shell to the tip of the highest pearl). Thanks!
  6. Posted this a few days but I didn’t have appropriate glue on hand. Now that it’s together, it definitely seems more tubular. Maybe a very weathered limb bone?
  7. My wife and I went on a 7500+ mile ramble to break out of our COVID doldrums. Due to the virus we had to change up many of our original plans... which conversely added a number of additional fossil hunting locals as they allowed us to mostly avoid our fellow humans and maintain social distancing by many many miles. As part of our trip preparations my wife sewed us a number of masks, including a whole series of fossil hunting masks for me. Originally we were supposed to stay in Chicago, but we elected to avoid staying in the city, so we only got to do a drive by We started the trip with a bonus dig, meeting up with fellow forum member @minnbuckeye for a guided Ordovician hunt in Fennimore, Wisconsin (THANKS MIKE!) Unfortunately I neglected to take pics of the site so I will only be able to share a farm pic we passed on the way. Mike was a gracious host who kicked off the visit with a gift of several fossil samples from his home turf As with all of the fossils from this trip, all finds are as they arrived back home, no prep. Some of our finds from Fennimore:
  8. Here’s another bone. Thinking it’s a ceratopsian skull part, but can’t match it to anything. Thanks! Edit: Now with more bones! The overall shape is arched with central canal.
  9. Lance Formation Bone

    Unknown bone from Lance Formation. Thanks in advance!
  10. Unidentified lance fm bone.

    Hi all, I was wondering if anyone can identify this for me my guess is triceratops frill but I’m not an expert.tia
  11. Tuesday on the White River

    Hello everyone! know I've been slacking on updates on my three week trip to Wyoming with PaleoProspectors, but I promise I will post some more of my finds and do a full recap of last week's adventure as soon as I can. As for tonight, I'll share my experience hunting in the white river formation today, A view of where I began my day hunting. My first find: A section of Paleolagus (rabbit) jaw. Next I found a native american artifact After entering a larger area of exposures I came across this Mesohippus (horse) jaw.
  12. For those who enjoy solitude and quiet away from large crowds of people, visiting the Blue Forest of Wyoming is probably one of the best choices. I personally love the most remote places possible, so I enjoy Blue Forest but those of you accustomed to living in or near a busy city may find it unsettling (or so I've been told). It can get busy during the summer, but overall it tends to be pretty quiet especially the further away from the road you go. I was able to visit the site last month and I found some very cool things. The drive out to the site really isn't too long in my opinion, but it's really not a site to spend 20 minutes at expecting to find a lot of big logs. Most of the really big logs have been found, so a lot of patience and persistence can (but won't always) pay off. Let me just say that if you plan to dig, it gets pretty warm out there. You'll need to take breaks throughout the day and rehydrate if you aren't acclimated to the dry heat. There was no wind when I was there and only occasionally would a few clouds dot across the sky so don't count on shade being there unless you bring a canopy with you. The first couple days started off a bit lackluster as far as digging was concerned. I wasn't finding much by digging, but when I surface collected I found a lot of nice small pieces. Different people have different methods of searching for petrified wood here. Some dig blindly, some probe and then dig, some witch for petrified wood, some probe existing holes, and some just surface collect. Each method has its merits. There has been a lot of digging here over the years, so the landscape is dotted with holes all over, some of which have been filled (if you dig here, please refill your holes so BLM doesn't try to shut the site down). I was finding a lot of nice small pieces on the surface where other people had been digging, but I was hopeful of digging up my own log. I'd heard about a few other people finding some small logs when I was there, but most said the same thing: they'd all disentegrated when they tried to remove them. The petrified wood here can be pretty delicate. It is encased in layers of algae, but extracting the wood from the algae can be difficult and often results in separation of the agate layer from the wood or even the log splintering completely.
  13. Hi all... A friendly shameless plug to invite you folks to tune in to PBS here in the states (and maybe Canada) this evening for the second installment of Prehistoric Road Trip. Check your local listings. https://www.pbs.org/show/prehistoric-road-trip/ I will doing the Happy Fossil Dance (it is in the previews) with the Tate Museum's rex, named Lee Rex. (My dance moves are better than Lee's, but not as good as host Emily's). Pickles the dog is sitting this one out, which is good, because her ego was out of control after last week's show. For those not in the USA, the show will be available for viewing (in Enbglish) after it airs. On the same link, but for a limited time only.
  14. Green River Trip

    I just returned from 4 days of digging in the Green River Formation. The quarry we dug in has 18”, mini fish, and upper gastropod layers currently exposed. Coming from Texas, we anticipated cooler temps but it was downright cold. High temps in the 40s and 50s with lows as cold as 30F! We had 1 day that was an almost total rain out but we dug 3 days and 2 nights on the 18” layer. We dug every day in the mini fish layer and randomly picked up pieces from the Upper Gastropod layer. On the second to last night, we went to bed in pouring rain and awoke at 3:00 AM to the tent collapsed on us due to heavy, wet snow! Everyone started pushing the snow off and the tent popped back up. Needless to say, we didn’t sleep much that night because we were now soaking wet and had to keep knocking snow off the tent. That was rather exciting g for Texans in July! Here’s our own little corner of the world. This pad of 18” layer produced some really nice fish, leaves, and a feather. Digging at night was a great experience, even though it was COLD!!!!! All in, we had a great time and I have piles of fish to prep now! More to come as I get specimens sorted and prepped. This was the view from the quarry after we finished digging on the last night of our trip around 1:30 AM.
  15. Hi everyone, I've been hesitant to post this fossil on here for a while as I didn't know if I wanted to hear a response which would contradict what I had hoped this would be. However, I recognize that to maintain a reliable and accurate collection I would have to properly identify what I found. The fossil in question is a possible partial egg that I found last year in the White River formation of Wyoming (Late Eocene/Early Oligocene) w/PaleoProspectors. This formation is known to produce fossil bird and reptile eggs (in fact, someone found a large, complete egg on this ranch the week before I was out there) so I knew that there was a possibility. When I found it most of the inside still contained sediment, which I have since gently scraped away to the best of my abilities. It has an odd dent in the top and no obvious pores, but the overall shape and the apparent shell make me think this is an egg. It is 8 mm tall and about 10 mm in diameter. I want to know what you all think. I would especially like to hear the opinions of @CBchiefski @jpc @MarcoSr @Auspex@Troodon Interior of the egg before I cleaned out the matrix. After I scraped away the matrix. Here's two views of the top.
  16. Large piece of Triceratops frill that I restored. Came out of the field in 65 pieces. Glued, pinned, puttied and color matched. But I have a question for the forum. In one of the photos, near the top edge, there is a round hole that I have no idea what caused it, infection maybe? Let me know what your thoughts are about the hole and the restoration. The hole does not go all the way through by the way. as you can see in the photos the pieces where coated with a thin layer of crust and had to be scraped and brushed. There were some missing pieces when all was glued and some very large gaps. The large gapped areas where pinned using a drill and pins, then paleo putty was used to fill in and match the contours. I experimented with coloring the putty so color matching with paint would be easier.
  17. Another Wyoming dig

    Last years dig season. Fossil was found lying on the ground, no digging. I was saying to myself is that what I think it is, not used to seeing or finding toe bones this large. Measures 17 inches in length. It was in three pieces which fit back together quite nicely. This was in the Lance formation and is complete.
  18. Oh what Frill

    Fossil dig in Wyoming, finally finished prep work. Glass of wine for my hard work. Couldn’t find the photo from the field, dug it out of hard sandstone and all the vein grooves were full of the sandstone. Love the grooves, some are very deep.
  19. A Fish Finger Prep

    I purchased this fishy piece a while back, as it was dirt cheap. It’s not much, more of a “fish finger” or “fish stick” than an actual recognizable fish, but once I got it in hand, I realized there was more buried in the matrix. Since I paid so little for it, I figured that when I had time, I would try my hand at prepping this little guy out to see what more I could reveal. I found some time today while outside watching the kiddos play, so I gave it a shot. It’s a fish fragment from Kemmerer, Wyoming. Eocene in age. What was initially revealed is only about 2cm long. This is what the piece look liked when I purchased it. Closer inspection showed more peaking out from the edge. I used my engraver on the lowest setting to slowly and carefully chip away the matrix. What fishy secrets will be revealed? This matrix is super soft compared to the local limestone that I’ve gotten used to digging around in. I have a new respect for the fish preppers out there! ( @Ptychodus04 and @RJB ) The tiniest slip would send a chunk of delicate bone flying, and with the soft, thin, almost chalk like matrix, a tiny slip was very easily done. The matrix was only a millimeter or two thick above the fossil so slow, careful, and deliberate movements were a must. A few more minutes revealed what seems to be the makings of a tail. This is as far as I was able to get until the kids wanted lunch. They think they need to eat a few times a day or something. Geez! The whole revealed piece is around 4.5cm long. It looks to be a tail, but that is as about as far as my knowledge goes regarding fish fossils... It still needs some cleanup with the pin vise and a consolidant added, but I think most of it is uncovered. Sorry for the slight red tint on this pic. I opened the umbrella for shade and didn’t realize it cast a red light on everything until after getting back inside and looking at the pictures. It was a fun little prep and I enjoyed trying my hand on a different type of fossil in a different matrix than what I am used to. A nice change of pace. Now where did I put the tarter sauce?! No wait... I need custard! Fish fingers and custard!
  20. NW Wyoming ID

    Just moved 40 to the SE of Yellowstone National Park in NW Wyoming. We have been finding these in the excavation of the house. They are located in a greenish clay layer just above a rocky layer approximately 12 feet below the surface. They are sedimentary balls that, when broken open, have a smaller, more hard type of rock or maybe fossil inside. We find them in different sizes from 4-12 inches in diameter. Any help would be much appreciated. Edit - I believe they are rare double concretions.
  21. Kemmerer, Wyoming trip 2

    Exciting news! Looks like I'm going back to Kemmerer Wyoming with my whole family! We're all doing a special trip there. I'm going to get in some fossil digging at the Green River formation, courtesy of fishdig.com. I've been there once before, last time I went there, I discovered a large Phareodus Testis. Also, my brothers two friends from Japan are coming to join us for this trip. I'm certain this will be Unforgettable to them. The date is to be announced. Probably end of July, early August.
  22. I took these photos of a replica of the Allosaurus jimmadseni specimen "Big Al 2" at the Lewis Science Center in Orange Coast College earlier this year. Like the referred A. jimmadseni specimen "Big Al", it was excavated at Howe Quarry in Wyoming in the 1990s.
  23. Wood? Bone? Stone? Nothing? (Wyoming)

    Hi! Thank you in advance for your responses. Whether this is anything or not, I'm thoroughly enjoying the learning process! Location Wyoming, near Cody (northeast). I found this while (unsuccessfully) searching for Geodes. This is from a large pile of transplanted rocks/earth which originated in the nearby hills. This particular pile is likely to have been originally 6-12 feet below the surface (I will be visiting that spot in a few days. I can upload a photo then for better context). WSGS data says the area is on the border of a Mesozoic and Cenozoic rock distribution. Interest I'm not sure what to make of this. It doesn't match the surrounding rock. I'm interested in the parallel "grains" throughout the piece, but confused by prominent grain-warping at a point near the outer edge. I really like the shell-like pattern of the coloration, but am curious about the inconsistent thickness at the rounded end. This is smooth to the touch (and sticky on the tongue...I licked it because the internet told me to...). This looks so much like a wood grain, but I see no rings in the grains, only coloration (though I understand not all woods exhibit rings?) I also have not found any images of petrified wood with a rounded end like this, so maybe weathering? Feels very solid (agatized?...that's a thing right?) Photos Link: Imgur Link to all photos
  24. Edmontosaurus Bonebed in Wyoming

    Over twenty years of work on the Hanson Ranch Bonebed in the Lance Formation of eastern Wyoming has yielded over 13,000 individual elements primarily of the hadrosaur Edmontosaurus annectens. Findings are presented in this paper. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0233182
  25. Fish scale or something else?

    I found what looks to be a large fish scale, but I’m not entirely certain. I would like some help with potentially ID’ing the species. I tried searching online, but nothing I found looked like what I collected. This was collected from the split fish layer of the Green River Formation at American Fossil Quarry in Kemmerer, Wyoming. It is about 1.5cm in length and width. Thanks for any help.
