  1. Percentage original?

    Hello, I am wanting to purchase this Andalusiana trilobite. It is 9 inches long, positive and negative. I know these are commonly heavily restored or completely fabricated. I also know judging fabrication by a picture can be very difficult. I was wondering if anyone could given me an approximate percentage of how much of this trilobite is original fossil. They are asking ... for this piece and was wondering if this is a fair valuation. Thank you
  2. Hello everyone, I was able to make a run down to the Conasauga River trilobite hunting site yesterday that was suggested to me in another thread. I didn't have an overabundance of time, but within five minutes of arriving, I found the specimen in the attached photo. It's not perfect, but it's the first time I've ever found a fossil out in the wild. Thank you to everyone for pointing me in the right direction. Now, since my time was a bit limited, I collected a five gallon bucket of the mudstone found there to look through it later. Now, some pieces seem easier to split than others. I've read on here that some people will soak items like this in water for about 15 minutes before attempting to take it apart. Does that sound right? I just want to have a chance at finding something else and minimize the risk of ruining a fossil in my quest to find one. Thank you, -William
  3. Hi all, My girlfriend and I are planning a trip to New York State sometime in September, and although her main motive might be shopping, mine is - you guessed it - fossils! Does anyone know of a place on could find Olenellus or Elliptocephala in New York? I know they can be found around Albany, but I can't find any obvious outcrops... Aside from where to find Lower Cambrian trilobites, any other suggestions regarding great fossil outcrops in eastern New York are much appreciated! Cheers, Marc
  4. Fossil News Summer 19 issue is available

    The Summer 2019 issue of Fossil News features the paleoart of Jimi Catanzaro, an article about late-Cretaceous pterosaurs in Cuba, more on that ammonite in amber you've been hearing so much about, an exclusive excerpt from Enrico Bonino’s new book about fossil medusozoans and how primitive algal mats helped preserve them, and a whole lot more! tinyurl.com/fnsubscribe
  5. I’m wondering if anyone has collected at the Spence Gulch site outside Liberty, Idaho, in the last year or so and would be kind enough to give me a status report. I have a chance to go before long, but random internet opinion seems pretty evenly divided between “great place, lots of fossils” and “bad quality rock, lots of work for little reward.” I’d be grateful for any help/info. Wendell
  6. Hello all, I am curious to know about the techniques people use for producing photographs for plates in paleontological publications. I know there are some professional paleontologists on here, so I'm assuming some of you have personal experience in this area. What equipment in general is ideal for this? I have next to no experience with photography outside of taking pictures of my personal collection with a point and shoot. The reason why I am asking is because I will be required to do so for my undergraduate thesis research (photoshoot of some Lower Cambrian trilobites) and I am having trouble finding good resources for this on the internet. Paleontology/biostratigraphy projects aren't all that common at my school, so I don't have very many people that I know personally to ask for advice. I've taken photos of my specimens so that I have stuff to look at in the field using one of the cameras from my supervisor's lab (the make escapes me, I can post it when I'm back on campus tomorrow). These photos were acceptable for my purposes (eye candy and IDing things with some references I brought) but are not up to snuff for publications. Just curious to see what people's experience is with this and whether or not there are any publications on the protocols that are used for doing this sort of stuff. Any and all suggestions are welcome! Thanks!
  7. Found near the original Burgess shale, this relative of anamalocaris probably fed in bottom sediments https://m.phys.org/news/2019-07-voracious-cambrian-predator-cambroraster-species.html
  8. I have come across, for sale, a pyritized agnostid trilobite from the Wheeler Shale. I was curious if anyone had seen these before, and if so, how susceptible were they to pyrite disease? It's quite a nice specimen but I don't want to waste money if it's guaranteed to rot in a year or two.
  9. I am putting together some educational displays and I am need of an example of a Cambrian age Pelecypod and Gastropod. Thank You
  10. I'm looking for the following paper: Q. Liu, H.L. Luo, L.Z. Chen and S.-X. Hu. 2006. Panlongia, a new trilobitomorph genus from the Lower Cambrian, Kunming, Yunnan. Acta Palaeontologica Sinica 45:384-392 My university has access to a lot of journals, but not Acta Palaeontologica Sinica unfortunately. If anyone has a copy or can point me in the right direction, it'd be much appreciated.
  11. Rostroconchia or Brachiopod?

    Howdy! I have a neat puzzle for the experts today! I know that rostrochonchia are not super easy to find... so I submit the follow picture. Most of the "shelled" creatures I unearth are brachiopods; cincinnetina meeki, Lepidocyclus, Rafinesquina...etc... HOWEVER! this specimen is unique to my collection. Found in northern Cincinnati - Upper Ordovician - The pronounced ridges are different than anything else found. Posted to an Ohio Fossil group, someone with a keen eye made the possibility of Rostroconchia. From my understanding these are not found often. Looking for help in identification. I do not have the tools at hand to remove anymore of the matrix without damage to the remaining fossils in the hash plate... (I have a dremel tools and dental pics...I'm lame) which are neat too. Rostrochonchia or Plaesiomys subquadratus (I compared to these specimens I had) As always, looking for education and conversation.
  12. Cambrian Chinese Fossils

    Well I haven't made an actual post on here to talk about fossils and for others to share pieces of their own collections so I will consider this my true maiden voyage here on FF! Today I wanted to share my Cambrian Chinese fossils, the Paleozoic era is probably my favorite subject as a whole in paleontology. There were so many different forms of life, so many different blue prints evolution had played with to see who would be the survival of the fittest. Unfortunately here in NY, there's not a lot of Cambrian fossils, some, but certainly not as many as there are in other places. So I had to focus my attempts in collecting illusive Cambrian fossils via purchase and trade. 1. Leanchoilia illecebrosa It's from near Kunming, China from the Heilinpu Formation. Roughly 518 MYA -Smaller specimen, but has some soft tissue preservation 2. Guangweicaris spinatus It's from near Kunming as well, but the Wulongqing Formation. Roughly 514 MYA -Not a complete specimen, but it would have been on the larger side if complete 3. Isoxys auritus and Yunnanocephalus yunnanensis (Depicted in images 3, 4, and 5) From the Heilinpu Formation. Roughly 518 MYA -Probably one of my favorite pieces in my entire collection, and easily my favorite of this collection. Positive and negative of both specimen 4. Redlichia mansuyi From the Wulongqing Formation. Roughly 514 MYA -Nearly complete 5. Yunnanocephalus yunnanensis Heilinpu Formation. Roughly 518 MYA -Small, but complete specimen My next target for this collection is an Anomalocaris kunmingensis frontal appendage, which have been eluding me since starting this collection. However, I hope everyone everyone enjoyed this post and shares their own Cambrian fossils as well. Until next time! (Hopefully will have better pictures too!)
  13. Iron-Petrified Stick with Vines?

    While rockhounding in the area of the Niagara Penninsula, I found an odd-shaped piece of metal about 5 inches beneath very thick, wet mud. The place in which I found the object was in a very shallow stream, which ran over sedimentary rock of the pre-Cambrian shield. After a closer inspection at home, I believe I may have found an iron-mineralized piece of a petrified wood, intertwined with two separate vines. A friend suggested it may be a rusty drill bit although I have doubts based on the location it was found. It is 3 1/2" long and 3/4" wide. It is heavy and seems hard like a metal. It is somewhat magnetic. It appears mostly brown, with spots of orange, and some light brown mud residue. I am assuming the vibrant orange colour is rust although there are also pale-orange spots which resemble the interior of a stick. Before cleaning the specimen, I would appreciate any opinions/advice. I am only able to attach two photos, but I will upload the rest in the response section. Any help is much appreciated!
  14. Last week, I made some incredible trips with my kids to the middle Cambrian U-Dig site, the Fossil Lake lagerstatte in Wyoming, and a muddy, rained-out attempt at the Late Cretaceous in Colorado. This was our first time visiting all of these sites - such amazing times! Here are some pics starting with Utah. My best find, a triple carcass Elrathia kingii Fossil Lake, first started splitting slabs in the Green River formation. This is where we were working. A large plate with three Knightias and a Diplomystus. Later we cut the plate down so could transport home. 18 Inch Layer: My son made the best discoveries at the 18 Inch Layer: a fly and a bee Bee under magnification. Incredible preservation detail! Some fish under scope We made it to the Cretaceous locality but it began raining. You can see the storm clouds approaching on the left. The roads were too muddy to continue and we were running out of time as we had a plane to catch unfortunately...another time perhaps! A beautiful drive. When we returned home it appeared the TSA searched my checked luggage! Luckily nothing was missing or destroyed. Thanks for reading.
  15. Cool new trilobite species described from Australia, Redlichia rex https://phys.org/news/2019-06-king-fossils-kangaroo-island.html
  16. Hi all, i'm buying that trilobite but i'm not expert in cambrian morocco trilos. That one seem real with no restoration but i'm not sure. Also not sure about species. Can you help me? Thanks
  17. Possible Chengjiang cnidarian?

    I acquired this enigmatic creature a while back and just rediscovered it in storage. It was found in the Heilinpu Fm, Kunming, Yunnan Province, China (Lower Cambrian, same age as the Chengjiang fauna). I have seen a few similar creatures offered from the same locality from a few sellers. It has been alternately labeled as either a cnidarian or ctenophoran. However, I've looked through a few dozen papers about cnidarians/ctenaphorans from Chengjiang and have found no similar specimens. Has anyone seen these before?
  18. Finding Cambrian Trilobites!

    Hey TFF Members! I was able to do something very different from the normal Florida fossil hunting the other day. On the way up to Michigan for my Mother's wedding I stopped in Northern GA to hunt for Trilobites! I was saying the age wrong throughout the video, I thought they were Devonian. But turns out they are actually Camrian... even better! Hope you can check out the video when you get a chance. I had an amazing time doing this!
  19. Short visit (1-2 hours) to famous locality near Las Vegas. I wish we would do better home work because some interesting trace fossils were identified only after we watched the video recordings. Perhaps, our "movie" will help you not to miss them when you will visit this unique place. It was a family Christmas trip, by the way. Also, if you know the species, please help with ID.
  20. Here are some color pencil sketches of some Paleozoic agnathans I drew many years ago (maybe 6 or 7 years ago). Time is scarce, but seeing these again I somehow feel inclined to start sketching some new concepts again Polybranchiaspis yunannensis (Galeaspida) Early Devonian Qujing, Yunnan, China Haikouella lanceolata (Agnatha, Haikouellidae) Early Cambrian Chengjiang, Yunnan, China Stensiopelta pustulosa (Cephalaspida) Early Devonian Ternopil, Ukraine Pteraspis (Pteraspiformes) Early Devonian Ternopil, Ukraine
  21. I recently bought this large trilobite fossil at a rock/fossil shop in Texas. After doing research I found that their are apparently Alot of fakes out there. The fossil itself has the same grainy mineral characteristics as the rock surrounding it when a flashlight is shined on it. The tiny sandy mineral deposits sparkle. I did a small bite test that an article I read suggested to do and it did not feel like resin. It was very gritty and the same texture as the rock that surrounds the fossil. Please help me if you can. Sorry it is only 1 picture. It wouldn't let me upload any more.
