Hello. New to the forum. Retired geologist (environmental) and ready to get back in to one of my passions, fossil collecting. As a young buck, I did lot of collecting in NE PA around the anthracite open pits. Late 70's went to USU and hiked a lot of locals in Wyoming and Utah. Anyway, just wanted to say hello. Jack....

I just got started on a stingray from the Green River Formation. It’s in a few pieces but I believe it is all there. Time will tell. Here’s the 1st section. As prep is beginning. 6 hours in: Time lapse IMG_1135.mov 17 hours in: The rays are so delicate, I’m limited to working around 3 hours max in one session before I need a break to rest my hand and mind. Any minor slip means that part of the specimen is destroyed and its 100% scribe work. No easy air abrasive on this guy, it would blow the specimen right off the matrix! It’s definitely a high intensity prep.

Hey all Can I please get an ID on these 3 fish fossils? All are from the Green River Formation. I want to say Knightia eocaena on all 3 but I'm not good enough to be totally confident in that ID. Can the small fossil be ID'd on the last fish? Scale is in cm. Thanks in advance!

Got some pics for you folks. Been doing quite a bit of prep and decided to get some of the little stuff out of the way. Looking at this I would think would make some folks wonder whats wrong with this guy? What in Tarnation is he doing? Must have some mental disorder? Once I've taken off all the things I used for weight, you can see how I have used a two part epoxy to glue on some 2 inch plate hangers Once I turn then over you can see the actual fish even though none of them are done. This is the one I wanted to get done but decided to do all four to save time in the long run. Plus it was too cold n the garage to do anything so I did these in our mudroom.

I know I dont post as often as I used to. Death of my middle son has a bit to do with that, but I'm starting to get back to life and not just go through the motions. After last xmas my oldest boy taught me how to Zoom and use an editing software program and I went head over heals with that and everything it entails. I've actually been enjoying prepping fossils again and making videos from that prep. Now, after some years, and with help from my youngest son I have finally cleaned up my garage and getting ready for some very large prep projects. and yes, all this prep will be turned into a couple of videos even though they wont be done till sometime next spring or early summer? In this picture, the front rock is one my youngest son found. It has 3 large diplo's and most of a large Noto. Ordered some new clamp on desk lamps to surround these slabs. Second huge slab is underneath that SawFish that Im trying to finish for my son. That huge slab is 2 inches thick, 5 feet by 2 feet and super heavy but loaded with the larger species of Knightia and all in some very good preservation. This rock is called marlstone and about as hard as the 18 inch and also loaded with gastropods. Gunna be a very interesting slab for sure. I will have to count the # of little fishys on it someday. I got this rock super cheap back in about 1995 or so from old man Tynsky back when he was alive. Gunna be two very long prep projecets but should be a ton of fun too. RB

I’ve been out of the prep lab for a week with an illness that knocked me on my rear. Yesterday, I got back in the lab and got to work on the initial prep on a large turtle from the Green River Formation. This beast is about 5’ long and came from the Mini Fish Layer. The matrix is a bit sticky but the bone quality is exceptional. It was found with a skidsteer while clearing loose rock at the start of last season, so it’s in multiple pieces. That makes it a more manageable prep but it would have been cool in one piece! This little guy is going to take me several months to complete. This section contains the head, part of the carapace and the left foreleg.

I ran into some really nice slabs of rock that have preserved bird tracks with rain drops, so I made a video. A little over 3 minutes long. Enjoy https://youtu.be/YVq7rYzA7Qg

Ive been taking plate hangers and rebending them to make them then fit onto my small fossil fish and even bought some copper wire to do the same thing. After hanging the last three fish and one of them falling down, I realized I didnt like that way of hanging them. Went online and found another way to hang these. I used 2 part epoxy to glue these onto the backs of the slab. Mind you, this would not work with the softer kind of rock like the split fish material. RB I layed the hanger onto some 2 part epoxy and covered with plastic and placed a flat rock on top. Days later they were as solid as can be! Here I am working my way around the electrical box but you can easily see the difference between the plate hanger type and the 2 part epoxy way of doing it.

Ive been back for a few days now and finally got around to checking out all the fish we brought home. I also met up with @Fossilis Willis and his buddy Jacob. Nice guys and boy o boy did they hit paydirt! We found lots of the smaller stuff but looks like maybe 4 juvenile noto's?!!! As I was going through all these little slabs I was putting the fish that were closer to the rock and in really good shape into my sons tote and the ones i or he didnt want to mess with into the "for sale' tote. This trip really beat me up and may be my last but was great fun to be out again. Going through the little stuff. Im doing the marking and my youngest son is doing the cutting. Nice to get them ready for prep. A nice little prisci. We found a few of these. A rather rare little juvenile Notogonius! Super happy with this one!!! Hard to tell in this picture but we had to leave this very very nice Phare with the owners. Did some crying over this one. Some of the bigger slabs we brought home. Hard to see but some more on the left.

My youngest son had to go to Denver to pick up a piece of equipment for his business, and like me, he decided to go the round about way and do some fossil hunting along the way. Him and his buddy went to Bonanza and spent 3 days looking and digging around. It took them awhile, he said they didnt find much of anything the first day, just wasting time digging holes, but then ran into a layer that had some decent stuff in it and kept following that layer for about 30 or 40 feet. They also found some insects and one very cool flower. I wish I took a photo of that. I will post more as i get some of this stuff prepped out. RB Here is a cute little leaf. If you look closely you can see where I prepped out the tips of three places and then I prepped out the stem. Came out purty dang good! It still has to be cut with the water saw but just about done. I will be posting more but have to prep it out first.

Here’s another torture prep. This is a little Diplomystus from the ultra hard bottom cap. This one is a bit harder to prep because there’s actually very little matrix on the fossil. So, it’s much easier to accidentally go through it with the scribe. I’m alternating between scribe and abrasive on this one.

I started picking at the back of one of my fish from the green river formation. To my surprise as I picked away matrix I stumbled across a patch of black substance. I continued to follow said substance as far as it went and the result was what looks to me like some kind of plant material. My first guess was a cat tail, but I have been unable to locate the stalk. Maybe it's a piece of petrified wood? I'm stumpt by this. If anyone can help me identify whatever this is it would be much appreciated.

Way back in December, I received a handful of fish from @RJB as a trade for some prep. I finally got the first one done! Here’s how it all began..

Ive always been very fond of the fossil fishy's. I also learned to aquire the little tiny fossil fishy's too. I have the little tiny phareodus and the little tiny priscacara, but today whilst going through yet more boxes of stuff, I ran into these little tiny beauties. The first, a 5/8 inch Mioplosis. 2nd, another Mioplosis measuring 3/4 inch and a very nicely preserved little 1 1/4 inch Knightia. Really made my day running into these!!! Just freakin love these!!! Life is really good!!! RB
