  1. The annual Charles Finsley Lecture hosted by the Dallas Paleontological Society will feature Dr. Mary Schweitzer this year. it's Thursday evening on the 29th of March and it's free but you must register. Details and a link for registration is at the DPS website. https://www.dallaspaleo.org/
  2.

  3. Muscle tissue?

    Stopped on the side of the road near the Petrified Forest in Arizona, to see what I could find and can't get over how much this piece seems to resemble muscle tissue, but thought that's gotta be unlikely. I did some quick research and found out there is such a thing, but it seems uncommon. Hoping people here with better eyes might be able to tell me what I am looking at. Help!
  4. 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.
  5. I have read many of Dr. Schweitzer's papers and am wondering what the safest methods to extract soft tissue from dinosaur bones are. I cannot find any information on this topic so I figured I would start here. By soft tissue I mean apparent original biological molecules such as collagen, red blood cells, etc.. Thanks for any help on this topic!
  6. Misszhouia longicaudata - 2

    From the album Chengjiang Fossils

    Misszhouia longicaudata from Chengjiang; all the appendages preserved.
  7. Misszhouia longicaudata

  8. Found this online. The seller claims it's an oreodont brain cast (with one end broken off). Was collected from White River Formation, South Dakota. It does to similar to an endocast.
  9. News story HERE. PDF paper in spanish HERE. Enjoy. Regards,
  10. I found a fossil during a recent outing in Southwestern PA, where late Carboniferous/early Permian plant fossils are pretty plentiful. With the usual fern fossil finds, one in paticular contained something I haven't found before. I used a chisel to crack open a rock and inside found part of a leaf stem and vein. I expected that it would just be carbon powder at this point, and blow away, but it appears the specimen is more intact. The specimen is a reddish brown color, is still pliable, texture like leather, and it does not appear to have transitioned to mineral composition. It is circled in the attached picture. There is a fossil of a fern to the left of the specimen, not a particularly amazing one, but I'm wondering if anyone else has found something similar, if this might actually be preserved soft tissue and if the leaf stem and vein might serve a better purpose in the hands of a researcher - anyone know if this might be something that would be worthwhile contacting some of the local college geology departments about donating or some other entity with tools and an interest in its study? I'm not sure how common or uncommon a find like this would be.
