  1. Past hour
  2. Some more pictures...
  3. Hi, There is this claw i have been looking at and i would like to know from the claw experts whether this looks genuine? The seller does state it has some fractures that have been glued and filled and the preservation plus the look of the overall shape leads me to believe that it is genuine. However most (or at least a decent amount of) large claws are probably fabricated to some extent and this claw is 10cm in length (4 inches). Part of the base of the claw looks to have a different colouration from one side so i don't if that is normal or not. Thanks in advance!
  4. Show us your plastic dinosaur

    I figured that you would like the Tree Rex one
  5. South Hills Site

    I moved up to South Hills, a suburb of Charleston, a few years ago and started hunting for fossils in the nearby creeks. The Charleston area is generally not great fossil territory, but I struck gold in Lick Branch. The creek is chock full of sandstone-replaced coal plants, mainly Stigmaria and Lepidodendron. I have pulled about 40 specimens out, the best one being the Stigmaria shown below.
  6. Here are a couple of my single and multi clam specimens- I only took pictures of the positive side of the concretion. Multi Examples-
  7. Very nice examples Rob, here are a few that I had handy to photograph tonight.
  8. Show us your plastic dinosaur

    This one is so busy that it hurts my eyes! Lol
  9. Real mosquito in Cretaceous Myanmar amber?

    It looks like a mosquito to me, but having a ruler or something in the picture for scale would make the ID easier.

    I hope you grabbed the other piece to the right of it. It kind of looks like maybe it popped off of it. Very nice!!
  12. Help with identifying oldstock Russian Ammonites

    Here is the second specimen. Thick guys. All of these have pretty opalescent Nacre If I need to post better photos I can do that. First (Above post) Single ammonite in matrix is 55mm tall x 45mm width x 14mm in thickness at the thickest part. Second (Bellow post) ammonites in matrix are (Left one first, Right one second) 47mm tall x 45mm width x 35mm in thickness 45mm tall x 34mm width x 32mm in thickness Thanks, StoneAgeQuarry
  13. Novice needing advice!

    G'day from another Aussie! I'm not really seeing any fossils here either. Can you elaborate more on where you found them in terms of their age, and why you think they are fossils?
  14. I recently acquired a collection of assorted rocks and minerals. Many of these specimens are from the 70's, 80's and 90's ( am in the US). In this group there is two ammonite in matrix specimens. I believe they are Russian due to them being pyritized. I am having a difficult time finding info about what species and what value these specimens may have. I go to the Tucson show every year and I don't often see ammonites like this. I was told to come here to find the experts! Thank you for your time, I look forward to posting more now that I am a member StoneAgeQuarry
  15. I have been asked this question many times. The non avian Dinosaurs died out the the end of the Mesozoic but many other animal groups survived. Among them were the Crocodilians. And people ask me all the time how they survived while the Dinosaurs didn't. So this has inspired me to make my first video on my dedicated Paleontology channel, Paleo Analysis. I am making these videos for the purpose of education so feel free to share this video as well as future videos! https://youtu.be/Gan8Vu4oM0w
  16. The matrix and preparation look very much in line with other stingray fossils I've seen. Like you said, it seems that stingrays are not commonly faked because of all those tiiiiiny tiny little bones in its fins. It's just super hard to do.
  17. There are eight reasons I love this species.
  18. I know the typical signs to look for in Chinese fakes, but this one is stumping me. It's got a pretty unique patina to it. Here's info and photos: Species: Oviraptor Egg Country of Origin: Taiwan (red flag) Origin of Find: China, mid-80's Measurements: 18cm x 13cm x 5cm (egg without matrix) Weight: 1,970g This seller's other items look legitimate so I'm hoping there's authenticity here. Lend me your special fossil eyes.

    Look at you trying to take credit when we all know it was all your evil ( not as good looking ) twin's idea!
  20. This amazing specimens is one of the favorites in my collection. It is a unique association of multiple Octomedusa surrounding an unusual and rare shrimp named Kellibrooksia macrogaster.

    Hi Snolly50, Oh yeah, that Grande book is great - a must-have for sure. Jess
  22. This specimen shows the crenulated edging around the bell.
  23. A very nice specimen preserving all 8 tentacles (rare).
  24. Octomedusa is a type Scyphozoan jellyfish. It is the smallest described species of jellyfish that can be found in the Mazon Creek deposit. The bell can reach a maximum diameter of approximately 2 centimeters. Like all Cnidaria from Mazon Creek, they are only found in the marine portion of the deposit. In the faunal study that I have referenced in previous posts, Octomedusa made up .03% of 230,000 concretions collected. Often times, only the bell is preserved. Well preserved specimens will show 8 tentacles. Depending on orientation in the concretion, some specimens will show a crenulated edge around the bell. Most specimens show very little raised detail and often appear as just a color difference in the rock. A large “X” shaped mouth opening is preserved in some better specimens. This first specimen shows most of the defining features.
  25. Dr Mud & The Crab Concretion Crusade

    Not on the crabs, but I know people who use an air abrasive to finish off the crabs. Ive used acetic acid on other fossils, but always see it as a last resort. I find it is way more labor intensive than scribing. Unless your fossil is acid resistant you need to protect the exposed fossil, put in acid bath, clean, neutralize in water, dry, protect new exposed fossil, repeat. I have thought about trying acid on a small concretion, as an experiment to compare with scribing though. I imagine the crab shell will dissolve quickly in the acid and you would have to be careful. Buffering the acid helps protect the fossil.
