  1. I'm trading a bunch of fossils mainly from Utah and Wyoming but some other locations as well. In return I'm looking for theropod teeth, ammonites, trilobites, crabs, gastropods, and more shark teeth or anything else that's interesting. You can reply here directly or PM me. I'll post another set some time later this week. Here is the assortment. Wyoming Knightia (Green River Formation, Eocene) Assortment of brachiopods, a crinoid holdfast in the middle, and pyritized worm burrows from Paulding Co, Ohio (Silica Shale, Devonian) Fossilized Great White tooth from Cape Town Another Great White: Knightia Elrathia kingii (Wheeler Shale Utah, Cambrian) The following Wyoming Knightia (Green River Formation, Eocene) Some are in better condition. There's a couple that haven't been completely prepared. I know some of you like to prepare your own fossils: Elrathia kingii More Paulding Ohio fossils (horned corals and brachiopods): A Phareodus scale: Another Great White: A St. Mary's formation Chesapecten conglomerate from Calvert Cliffs, MD:
  2. Hello I found this at the isle of sheppey months ago and am still unsure what it is. It does remind me of bone, I was thinking a partial jaw bone of something but unsure, any help with be appreciated, found at the isle of sheppey, Kent, UK.
  3. White river: How hard?

    Hello all I don't have much prep experience, and since I have very bad eyes I have trouble with microscopes to prepare fossils. I would like to learn how to work with my airscribe tought. So I want to prep fairly large fossils I can do without microscope. I have some stuff from France and Belgium I found myself, but or these don't need prep, or I don't dare to because I don't want to destroy my rare self-found fossils. So I came across the fairly common white river stuff. I found a website where I can buy unprepped oreodont bones and skulls. But what do you to prep these? Are they possible for total newbies when it comes to prepping? Is the matrix fairly loose or is it very stiky? I have an air scribe but don't know how to use glue. I've tried trilobites before but those are too tiny. I'm looking forward to your advise.

  9. Eocene Sponge Identification help.

    Hi everyone! I have been cleaning out, organizing and labeling the mounds of sediment buckets in my garage. Plenty of time over the holiday break to try and get my mind back in to the fossiling mode. I tried at the beginning of this year to get my Friday excursions going again and venture to some quarries, but there are limited areas which the fossil hunter may tread now a days. Then priorities in life too . These buckets of sediment have been waiting for me for many years and months, just waiting for me to take the time to investigate their treasures. I started a few days ago on a few of my Eocene, Castle Hayne Formation, North Carolina buckets. Many bryozoa, crinoid, echinoid and occasional crab claw specimens appeared during my screening and washing. Several species of sponge too. I came across this dandy lil' fella and would like to ask for some assistance in identification. Has that "sponge" look to it and seems to have other characteristics. I did not find it in the NCFC Invert Book or my other Invert books. Any help is greatly appreciated. Best, .

  23. More Kingsbury TX finds

    Hi everyone! Holidays mean more time to photo and post. As previously mentioned in my previous post, I am finding a lot of fossil impressions and voids in chert and mudstone on a small artist residency and farm in Kingsbury, Texas, in Guadeloupe County. And some petrified wood. Most of the casts I find are pelecypods and some gastropods; however I am finding some other stuff, some of it total mystery. This time I will post the mystery items first. Let me know your thoughts! This first mystery (3 views) has tight incised lines around the darker shape - most evident in central photo. The next item, below, has lots of impressions. The closeup on right shows a spiral on left side, is that a worm, or a gastropod internal cast/mold? I think the horizontal cavities on right of closeup are some kind of coral? Here's some coral ... or petrified wood? (two images Photoshopped together) And also...the below is super interesting...at first I thought it was just a chip, or a shell impression. But starting to think insect wings! At first I thought this could be a bryozoa (left photo below), but I think it is more likely a worn pelecypod impression, re like the typical one on the other side other rock (right photo). And here's some pet wood, various types And bone? Or coral? I keep thinking bone because of smooth sides.
  24. Cyclurus macrocephalus Reuss 1844

  25. Knightia and what else?

    This fish fossil is from the Green River Formation, These fossils are enclosed in a thin layer of shale. The vertebrae are 33mm long, possibly Knightia? On the left upper edge of the rock is a fin. I had a x-ray taken and I see several straight pin shaped ribs? However they are a poor match for ribs described in "Paleontology of the Green River Formation, with a review of the fish fauna" (Grande, 1984). These "ribs" are very straight. There is also the central rod-like thing, which is perhaps plant material? I thought a X-ray would review hidden secrets, but it hasn't really adding anything I couldn't see with my naked eye. This forum is a joy to browse. I'm very appreciative of the responses I've gotten from my previously ID requests so far. I am certainly learning! Any ideas as to what I'm seeing?
