  1. Cambrian Trilobite ID

    Below is a Trilobite fossil from the Arthur Creek Formation (middle Cambrian) I found some months ago. This formation is located in the Southern Georgina Basin in Central Australia, in a remote location between Northern Territory and Queensland. I hadn't attempted preparing a fossil before and decided to finally give it a try. I wanted to see if the Cephalon was present and still intact and if I could carefully uncover it. I'm quite pleased with how it turned out, as the fossil is comprised of a very dense sandstone and I was told it could be a challenge. Now I have it fully uncovered I wanted to see if anyone could help with identification. From the reading I've done I'm thinking it's Xystridura Templetonensis. The two circular sections either side of the Glabella, which itself is quite circular line up with other examples I see of Templetonensis. I find it hard to get an accurate thorax segment count, but I believe I see 13, which would also line up with what I thought. Thanks for any help!
  2. Superficially, this beauty looks just like the pics of live ones from Shark's Bay, Australia. Central Pennyslvania, USA
  3. Cambrian Trilobite Unknown

    A few weeks ago, we took a little drive through the rolling hills of SW Wisconsin. I had to occasionally pull over at some road cuts and stretch my legs. While stretching, why not look for fossils! Here is a pygidium that I can't identify from that trip. It is 5 to 10 times larger than other pygidiums that I normally find in the Eau Claire Formation of the Cambrian Period. Any thoughts?
  4. Hello to all! I have recently won the rolling auction here on the forum, and one of the items included was a Cambrian panlongia from China. I understand that the two species of Panlongia can be distinguished by the presence of spines along the sides of the thorax but I really can't tell on this piece, so if there is any other way to know which it is I would love to hear it! At the same time the same piece of matrix features something else right next to it, I am not sure what it is, could it be a brachiopod? And when flipped over there is another fossil looking object below it, is this some kind of ichnofossil or something else? Thank you very much, Misha
  5. Trip to Sweden

    Today I would like to describe my trip to Sweden. Since I visited several locations, it’s going to be quite long – but I hope reading my report is going to be interesting enough for you to last until its end . I include only a few pictures of fossils from each location, because I’m still in the process of splitting the rocks I brought with me. First a few general impressions about Sweden – it’s a super super green and clean country, with lots of beautiful natural reserves and naturally – fossil sites. I was hoping the weather in September would be still good enough to do some fossil hunting and outdoor sightseeing, and we were really lucky, because although the temperature dropped a few times below 10 C, at least it didn’t rain We took the ferry from Świnoujście to Ystad and from there I went to the first location – Brantevik. There is the place where the boundary between the Cambrian and Ordovician is located, so on the beach you can find rocks with fossils from both periods. The location looks like this: And here are some of the finds: The next site was actually the “youngest” among all the locations I visited – it was Ignaberga, an open-pit Cretaceous quarry. I guess it is still operating, but fortunately I was there on Sunday, so nobody was there. It is very easily accessible – and the slopes are literally covered with brachiopods
  6. 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:
  7. Thought I would share some specimens from my recent trip to the Mt Scott Range, near the town of Leigh Creek and about 540 km north of the city of Adelaide. These Arachaeocyatha can be found just beside the main road and are from the Ajax Limestone, of Lower Cambrian age (528 Ma). I am not able to indentify genera or species but many types are represented. Best way to see them is to either find a sample that has been naturally weathered, which shows up the structure in relief, or cut and polish sections. The last photo shows a longitudinal section of one showing both the double wall structure of the caylyx and also the attachemnt holdfast.
  8. Hey hi Y'all, Was looking at some of My trilobites from My last trip to the House range and found something that is not a trilobite. Wheeler shale, mid cambrian. Any help to make an ID on this thing is always appreciated. Thanks. It is 1 cm long.
  9. 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
  10. 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
  11. 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
  12. 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
  13. 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
  14. 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!
  15. 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
  16. 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.
  17. I am putting together some educational displays and I am need of an example of a Cambrian age Pelecypod and Gastropod. Thank You
  18. 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.
  19. 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.
  20. 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!)
  21. 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!
  22. 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.
  23. Cool new trilobite species described from Australia, Redlichia rex https://phys.org/news/2019-06-king-fossils-kangaroo-island.html
  24. 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
