  1. Hello everybody, This is my first post and first piece of artwork I would like to share and, hopefully, receive some feedback. I do 3D animation and rendering for living, but paleontology is my life long interest and passion. Here is my 3D reconstruction of Cambrian trilobite Olenoides serratus that was a common member of the famous Burgess Shale biota. I actually live just 250 km apart from the famous Burgess Shale quarry (and 100 km from Albertan Red Deer badlands rich with dinosaur fosslis).
  2. Cool rock or finally a fossil?

    Again, it's small enough that pics are tricky to get with my phone. I've posted the interesting side, the side, and the flip side. What do you think?
  3. Hi all, I am going through the latest finds from our trip to the upper cambrian Abrigo Formation from south eastern Arizona, and one of the limestone pieces under magnification had some intriguing fossils. The fossils are calcified as are all the trilobites and brachs in the same material from this site, and are small spheres about 1mm in size with a hole in one end. My first thought was some sort of protist, but my micro paleontology friend suggested they might be tiny round sponges. I have lots of photos to share with you on these enigmatic fossils. What do you think? 7x view of a gaggle of them on the limestone: And a series of 40x close ups of individuals: Microsponges or non fossils?
  4. Hi all, Winter is the perfect time of the year to collect cambrian fossils in South Eastern Arizona. Its temperatures are perfect, its not raining and traffic is low. We will have lots of material to cover here, but I thought Id start off by posting a few shots of tiny inarticulate brachs from tonights scope shooting session. I used photoshops "contact sheet" function and it worked pretty good. The Abrigo is middle cambrian and upper cambrian. The lower part is the same age (and ocean) as the Bright Angel Shale in northern Arizona. The upper Abrigo is upper Cambrian and is a latter period which is not represented in the BAS. I wont be identifying these at this point, but they are probably Lingulella or Billinslella sp. Oh isnt the Cambrian FUN?!
  5.

  6. Tonight I decided to split some of the Georgia Cambrian Conasauga Formation matrix that I have. Here are some of the complete/ near complete trilobites that I found.
  7. Cambrian arthropod?

    Need help to identify this, it could be rare, but not sure. If not a naroiid, or soft bodied trilobite, than what could this be? Found at Little Hollow Formation...Cambrian, Nova Scotia. It is extremely small, barely visible to the naked eye. Tip of ball point pen for scale. I have magnified it with a digital microscope, 250x magnification. Has anyone ever seen this in their research or studies of fossils?
  8. Revisiting a Burgess Shale Monster

  12. trilobite cephalon

    Hi. My name is Adam and I'am new to the forum. I am trying to identify correctly all my fossils and more i read than more questions I have. first position in my catalogue of fossils is this trilobite cephalon from Latham Shale, Providence Mountains in California. Previously was identified as a Fremontia fremonti but I am not sure about that. It's 26 mm wide. I don't know if the details of the specimen are good enough to say what species is it. I would be very pleased with some help.

  15. Cambrian Sponge?

    I apologize that this is just one photo taken by my phone, but that is all I have to use at the moment. This fossil (about 6 cm long) is from the middle Cambrian Spence Shale of Oneida Narrows, Idaho. I am leaning towards a sponge? Does anyone have any idea what this is? Thanks for the help!

  18. U-Dig

    Had an awesome day digging at U-Dig with @FossilSloth So the hound and the sloth hung out today and we pounded rocks from sun up to sun down. I found the largest Asaphiscus wheeleri I've ever seen and Justin scored a good number of Elrathia kingii. The find of the day a was massive Asaphiscus wheeleri. The trunk is full of Utah trilobites to prep this winter. Had an awesome day. Exhausted yet determined to find some more. The U-Dig season closes soon and I already miss this place. Justin and I holding up some of our finds. It's always fun meeting up with another forum member. Justin hauled off seven buckets full of trilobites, sponges, and brachiopods! One of Justin's buckets. I see an Elrathia kingii multiplate! Another Elrathia kingii awaiting preparation. Really going to miss this place. Sunset over the ancient sea ways. Up close of the day maker. Another angle. I'll post more trilobites as I prep them out. Found a myriad of Perenopsis and will post those later. The site manager showed us a secret spot full of them. Here is a video of all the neat trilobites we found in between one of the Shale slabs: That's all for now folks!
  19. Seen a few weeks ago, during my visit to the dinosaur museum in Espéraza (Aude, France), this tagged bilobites slab molding! (original slab on the edge of a road..)

    Perenopsis multi-plate from U-Dig. @Kane an old timer to the site showed me were to find these and after a few hours I found a couple with 5+. I said I'd get you another one, but perhaps I could up the stakes for another E. rana. Stay tuned!

  23. Sponge again

    From lake shore glacial deposits adjacent to the Hurricane Mt. formation. Terms like altered and dynamic are used to describe the formation, but the sponge Diagoniella was used to date the deposits. Could this be an example ?
  24. Adam's Cambrian

    A rangeomorph holdfast trace fossil from the Ediacara formation, Rawnsley quartzite of the Flinders Range, South Australia. This specimen is Medusina mawsoni, so called because it was until recently thought to be a jellyfish, but is now believed to be the attachment point of a fractal rangeomorph as Charniodiscus is the point of anchorage for Charnia sp. This one may have been the holdfast point for some species of Rangea. The diameter of the outer circle is 1.5 cm and the fossil is estimated to be 555 million years old.
  25. Hello! It's been a loooong time guys! I'd like to introduce some Korean trilobites to you and share some of my experience in fossil hunting in Korea(South). I went to Gurang-ri[GuRang-ri], Mungyeong[MunGyeong], Northern Gyeongsang-do[GyeongSang-do] on June, 23th, 2017 for hunting trilobites. (By the way at this time, I went there by in my brother's car, finally! I practiced a bit after I had gotten the driver's license. Maybe I'll go to Jiggunsan formation on December in brother's car, again! *:D*) Anyway, I found the location and some information from a dissertation, which was posted by a high school teacher(it was written in Korean. Maybe if you can speak Korean, then I can share it :)) The teacher found 2 kinds of specimens from different formations. One is Gurang-ri[GuRangRi] formation and the other one is Hanae-ri[HaNeRi] formation. One is "Kootenia amanoi Kobayashi, 1961" and the other one is "Redlichia nobilis Walcott, 1905". Actually, I was going to go to Jiggunsan formation 'cause that site's fossil output is better than Gurangri formation. You know, I had hit the rocks for about 2 and a half in the strong sun(at that time, the temperature was around 95°F(35°C)) and I found just 7 specimens. On the other hand, I found about 60 specimens in 2 and half hours in Jiggunsan formation. I grabbed the steering wheel with excirtement The quote from Robert Stevenson crossed my mind at that time: "To travel hopefully is a better thing than to arrive". Before going to the fossil site, it was really excited. But I thought that I would trembke with excitement if when I could meet some trilobites so much so that when I encountered faint galaxies or stars through the telescope. (Highway rest stop. The big words(충주휴게소) on signboard means Chungju[ChungJu] rest stop.) When I got to this rest stop, I reminded that I forgot to take mosquito repellrant. So I bought a new one and had blunch from near here. After arriving at the fossil site, I couldn't find the actual formation. With perplexed feeling, I just knocked this seems similar sedimentary rocks which depicted as red-purple colored layers. *Gurang-ri[GuRang-ri] formation And I found something strange structure. I thought that it was some strange metamorphic structure or bivalve fossil. However, after took a closer look, I felt something is strange and finally I realized that it was trilobites' head shield! The images are Redlichia nobilis Walcott, 1905 I took these pictures when I was in my country. So, I couldn't change the coin to other countries' coin or ruler. Its size is almost 1" or 25 Canadian cents. Redlichia's cranidium. Thorax part. Another cranidium preserved as cast(positive). This one is mold part of the above image. One part of thorax. Not that good preserved but still can see some glabella. Cranidium and librigena(free cheek) Librigena(free cheek) and strange fossil cast part. Mold part. Librigena(free cheek). Strange fossil. I don't know what it is. Thank you for reading this long post! Next time, I'll update fossil hunting at Humber river, Toronto, Ontario. And Brechin quarry and Bowmanville quarry. Thankfully, Joe from Michigan will take me to there! I REALLY appreciate it!
