  1. 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.
  2. Lance Formation Bone

    Unknown bone from Lance Formation. Thanks in advance!
  3. 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
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.
  12. 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!
  13. 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.
  14. 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.
  15. 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.
  16. 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
  17. 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
  18. 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.
  19. Theropod tooth (Labelled as Nano)

    Ok, I have given a go at doing some ID on this myself, using the very helpful "identifying theropod teeth from the Hell Creek/Lance Formation." thread. But hit a brick wall. So, if anyone could A) Let me know what this tooth is and B -- If I am on the right track with my amateurish ID attempts, that would be amazing. So, I got to eliminating it as being a Nano (Because Nano teeth are apparently rectangular and this is quite ovalish. And eliminating it as being a small version of a T-rex tooth because it isn't fat and the tip doesn't look right. And eliminated Archaeoraptor as it being a bit big. Eliminated Dakoraptor because the recurve isn't enough. This is my first time having a proper go at IDing a tooth for sale beyond googling similar--so odds are I've missed something obvious or got it completely wrong. So, it is labelled as theropod Nanotyrannus, Lance Formation, 0.5 inches in length. Any help, as always, much appreciated.

  21. Belemnites vs crinoids, tooth

    Found these tubular fossils in the Cody Shale in the Bighorn Basin or Wyoming. Friends state they are squids of some type. I can't find any type of belemnite that would fit the bill. Are these possibly crinoids? As for the tooth, found laying on top of soil in this Cody Shale...our friends state they have never found a tooth in this area prior. (see photos next post) Thanks, Dean
  22. Lance Fm. Sacrum?

    Here's an interesting looking partial bone I found in the Lance fm. of Wyoming back in 2018 with PaleoProspectors. The guide I was with thought it could've been from the hip region of a reptile, possibly a champsosaur. After a few years of gradually improving my identification ability I now think it's a partial sacrum, but I am not sure. I want to know what my fellow forum members have to say about it.
  23. Didn't do the lick test on this one

    I found this odd little pebble in the Lance fm. in Wyoming over the summer and have yet to post on the forum so I thought I'd do so tonight. Anywhere else I probably wouldn't have kept it, but since I found it in a dinosaur bearing formation I was thinking it had the potential to be a gastrolith as it's completely smooth and rounded along with being a different color than most of the surrounding sediment I found it in, possibly hinting at transportation from its origin. I'd like to know your thoughts as I think it would be really cool to have found a dinosaur gastrolith. It's also not a piece of rabbit or deer scatt as it's not squishable (trust me I've accidentally picked them up before out there).
  24. Trying to find out what kind of crystals he's our guy was told it's just a different type of Amber they look kind of like fools gold little half domes not sure
