  1. 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!
  2. Greetings everyone! Today I had the very special opportunity to collect in the Whetstone Gulf formation at Martin Quarry. I had a really great time and I just wanted to share some of my finds with you fine fossil forum folks! Enjoy
  3. Good evening again!. Amazing what you can find jut scanning shale after shale! I find multiple clusters of conodont segments and denticles but tonight's find is potentially very exciting!. Surrounding the elements is a finely granular, uniform, brown matrix which is not shale (arrow) and not sediment (at least my thought . I see this on occasion in shale but this is the first time I've found it uniformly surrounding conodonts. to me it appears organic. Thoughts? thanks so much again!!! Bone

    Whiskey Bridge Oddity

    Howdy folks, About Ten years ago, on my first and only trip to the famous Whiskey Bridge in Bryan Texas, I unknowingly found and brought home not one, but two cephlapod fossils. Well, I smashed one thinking there might be some “cool shiny mineralization” in this odd odd rock that seemed anomalous and out of place since all I read about were shells and sharks teeth. Shameful... I know... however, something strange looking fell out and I held onto it, taking care to store it carefully due to it, and the fossils themselves, being siderite and prone to oxidizing. It’s current state is

    Possible Eyeball ??

    Hello, I have found a Fossil that I cannot ID. The fossil looks like an eyeball in its socket. There are fine strands around the ball, looking like they are holding the ball in place. Can anyone help me ID this? Thanks Dave
  7. Hey everyone, I just got back from an amazing trip to Utah and Nevada collecting a host of trilobites. I am going to try and post some photos of that trip in the next day or so. I never seem to be able to find the time anymore! This find was pretty much the trip maker for non trilobite finds. I found this soft tissue arthropod in the house range in rocks known to have Burgess Shale fauna. So far this doesn’t seem to line up with anything I’ve seen in the Burgess. I’ve had 2 suggestions on an identification. Canadaspis perfecta is the best guess so far however there are g
  8. Timer period: Pennsylvanian Location: Missouri Formation: Not exactly sure. Found in an abandoned rock pile containing limestone from the Iola Limestone Still it is a possibility it came from limestone from the Upper Winterset limestone. Hello! I found this nautiloid a long time ago and it was too heavy for me to carry the chunk of limestone that contained it, but before I left I got a few pictures of the specimen! Once I observed the photo a few weeks later I had the biggest regret of my life as it might contain an impression of soft tissue! I don'

    Possible Soft Tissue fossil?

    No idea really what I have. Anybody have any advice or info? Thanks!
  10. Origin unknown; found in box of junk at yard sale. Guessing it is some type of clam from regular ridges on outer part of piece; inside piece has blackish "softer smoother" piece than outer hard piece. Has striations like gills or hair? Is soft tissue normally found in fossils? Kind of thought they would be the first thing to dissolve when something dies; if so what is it?

    A worm or worm burrow in New Jersey?

    Hi everyone! I recently found this strange curled relief on a rock in Monmouth County NJ, due to the prevalence of burrows at this site, my guess is that this curl could be a worm (unlikely due to the whole soft tissue thing) or a worm burrow, or perhaps one of the tricks bog iron likes to play. Anyone got any ideas?

    Wikipedia's Cretolamna

    Hi everyone, I am seeking more information about the spectacular Cretolamna fossil featured in the respective wikipedia article. Aside from being a great fossil it has some interesting features, such as a large second dorsal fin. However, there doesn't seem to be anything else online about this specimen. Does anyone know anything about this - is it in a private collection? Can it actually be referred to Cretolamna?
  13. This is a really interesting article on imaging techniques used on concretions: https://www.palaeontologyonline.com/articles/2013/patterns-in-palaeontology-exceptional-preservation-of-fossils-in-concretions/

    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.
  15. 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/

    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!

  20. 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.
  21. News story HERE. PDF paper in spanish HERE. Enjoy. Regards,
  22. 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
