  1. I’m looking for a complete high quality Elrathia kingii still in matrix. If there are multiple on the same plate even better. I have a variety of fossils from the Chengjiang biota and several Devonian trilobites (Penn Dixie and Morocco) available for trade. PM if you’re interested! Thanks.
  2. Pre/Cambrian Collection

    I have always been quite fascinated with the early stages of development of life on Earth. My interest really picked up when I first discovered the Ediacaran biota, and who can blame me. Those creatures are so enigmatic and fascinating. I was able to pick up a few specimens, but quickly realized that my desire for fossils greatly outweighed the supply and cost of Ediacaran fossils, and I soon discovered the equally fascinating and enigmatic Lower Cambrian Chengjiang biota. I was, and still am, blown away at the quality of preservation of these soft bodied critters. A lot of specimens come very shoddily or incompletely prepared, and while it's been a steep learning curve, I feel that I'm starting to get the hang of prepping them. I've decided to start posting my latest acquisitions as these fossils are too amazing not to share. First up is Cricocosmia jinningensis, a fairly common palaeoscolecid worm from the Chengjiang biota. I have several specimens but this one is the best. It came partially prepped and I am just now satisfied with the result. You can see remnants of the gut preserved as darker regions in the center of the body. Next up is a small hash plate of Bohemiella romingeri brachiopods from the Middle Cambrian of the Czech Republic. Not my usual purchase, but I felt the specimen was too beautiful to pass up.
  3. I recently got a nice deal on this Leanchoilia illecebrosa specimen from the Chengjiang biota. It looked like a dorsally compressed specimen which rarely have appendages preserved, so I was just expecting to clean up all the tool marks. However, while cleaning it up, I realized that it is in fact laterally compressed, and actually quite well preserved at that! The legs are starting to come out, and part of me is hoping that other appendages might be preserved as well. All prep is done with a needle under a magnifying light. It's going slow since I need to be very careful, but it's getting there.
  4. Unknown Chengjiang Microfossils

    I was splitting a piece of shale from one of the formations that holds the Chengjiang biota, and found quite a few of these small things. They're no more than 2 mm in length and to the naked eye, look like small red lines. The pictures below were taken at 4x magnification (first picture above is one specimen, latter three are another specimen). First thought was some segmented worm, but I'm not super convinced. Any ideas?

  7. Spot the Vetulicola?

    There is a Vetulicola (partial) somewhere on this piece, I have been looking at it for awhile but I can't really spot where it is on here, anyone more familiar with Chengjiang fossils able to spot it or id for sure as vetulicola?
  8. I don't think this one has been posted yet... http://www.sciencemag.org/news/2018/08/these-half-billion-year-old-creatures-were-animals-unlike-any-known-today

    From the album Finest Chengjiang

    A fine example of this early trilobite with one antennae fortuitously preserved.
  16. Leanchoilia sp?

    From the album Finest Chengjiang

    I'm not certain of the species as all the tergites are not present, but whatever it is, it's amazing. The colors are slightly enhanced to reveal details of its limbs and antennae.
  17. Naraoia spinosa

    From the album Finest Chengjiang

    A complete specimen of an iconic Chengjiang species. Details of limb imprints and digestive diverticula can be seen.
  18. Misszhouia longicaudata

    From the album Finest Chengjiang

    A fantastic example of this iconic early arthropod. Though incomplete, many pairs of biramous limbs can be seen, as well as details of its joints. The colors have been enhanced.
  19. Cambrian Tectonic Plates

    Anyone have any information on tectonic activity during the Cambrian Period? I am writing a report on tectonic activity on Earth and am going to use the Cambrian to explain the location of the Burgess Shale and Chengjiang formations. So far I have a good idea of what I am doing, just wanted some input from others. I'll reference anyone that responds. Thanks.
