  1. Here are images of the 6 honeycomb pattern patches found in my Wheeler Formation collection. First image: 1 mm long Second image: 1mm long Third image: 1.5 mm long One image missing - couldn't get to focus. Fourth and Fifth images: 2.5 mm long. These are facing images of each other - original fossilized and impression - same specimen. I tried my very best, but images are still a little fuzzy, despite higher magnification.

    Paterina or Obolus

    This is found in North China's Henan Province, mid Cambrian rocks, together with Bailiella. Obolus is much mentioned for this layer ( mostly very small, about 1mm) . This one is not only bigger, but also looks like a bit similar to some Paterina, to me.

    Honeycomb-like structure

    I have gone through 200 pounds of Wheeler Formation and found only 5 of these (2 are the original, and the impression of one specimen). I must have missed the impressions or originals of the others. They are difficult to spot. They are honeycomb structures, almost microscopic patches, just sitting on top of, but firmly attached to, matrix. These patches are not any bigger than 3mm at their longest dimension. Only one of them is that big, and they are all roughly circular or oval in shape, no boundaries, no distinct edges. The others range in size from 1mm, to 1.5mm, to 2.5mm i

    Holochroal Trilobite Eyes?

    I found these (almost microscopic) honeycomb patches just laying on top of matrix. They are not attached to any trilobite, but what else could they be? Molted off? Sorry, I tried to take photos of them, but the detail is just not coming up. They are perfectly crystal clear when viewing under the stereoscope. I probably need a better camera. Will try later if/when I invest in something better. Has anyone else found tiny honeycomb patches in wheeler material, not directly associated with trilobites? I am finding both original fossilized and their impressions. I
  5. Ok, several more photos. Now, these strips of oxidized material also have those very tiny filamentous fibers running along their length in the same direction as the strip, somewhat like the grain you see in wood. These may be degraded specimens, with only a few single fibers left. Some have many more fibers per square cm. Remember the oxidized hash (yellow/orange) I showed you previously which is just filled with these fibers? Maybe this particular stuff is actually a clump of algae, and not necessarily just tracks. Maybe the strips without fibers, but instead with ot
  6. Other trilobites I have found in the wheeler. Asaphiscus wheeleri Only one complete with impression. Lots of fragments. Note the huge, broad pygidium.

    Margaretia dorus

    I just managed to find most of a frond of Margaretia dorus. Usually, it is represented by ribbon-like strands with tiny fibers running along its length, and frequently iron-oxidized. See photos of posts Ichnofossils, Algae, or Something Else, parts 1 and 2, under Fossil ID. This particular specimen (original fossilized and impression) is fairly three dimensional, and carbonized like the trilobites from this formation. Note the oval holes (pores?) running along its length! Margaretia dorus was originally thought to be an alcyonarian coral, then a green algae similar
  8. I have Elrathia kingii, Itagnostus interstrictus, and Acrothele subsidua. Also, rare rock and mineral from California, eclogite and benitoite..
  9. These are very tiny, delicate, fibrous/filamentous structures which are most commonly found within an iron-oxidized (? yellow/orange tinted) hash. They are probably part of something bigger, like maybe the fibrous structure of highly degraded algae. These are really hard to photograph with what I have. Again, 3ach circular shot 9mm+wide.
  10. I need your opinions, please. Burrows, I think.

    Itagnostus interstrictus

    Found during a trip out to a hill right adjacent to U-Dig Fossil Quarry. The trip report can be FOUND HERE. This is the largest I've collected. Typical sizes I've found are 3-6mm in length, 1-3mm in width.
