Recently recieved a nice little package of lance creek lag formation matrix for me and a close friend to look through. I personally never handled a tough hard more dry matrix like this as I'm mostly a creek digger and my friend she is a complete amateur so this will be her first time. I'm looking for any helpful tips on how to approach such matrix. It came with two wooden sticks and some strange glue made of beads that I heard u would need acetone to break down, and if that's the case what would be the proper amount to mix? Also would it be a good idea to use the wooden sticks as a digging tool to break up the matrix? And lastly what would be the best approach coming across a fragile more broken up bone? Any help to make this experience smoother will be very much appreciated as I'd love to make the fossil hunting experience especially more smoother and special for my friend.

I found this today in the Hill Country of Texas, Northern Medina County. It was about 1/2 mile from the Medina River, at the base of a short upslope. The red, or maroon part feels like it has enamel.? It measures 1 1/4” long by 5/8” tall by 1/2” at the widest point. The smaller piece fits into a groove on the maroon part of the larger.

Water was high and cold today but I found some cool stuff at the North Sulphur River Texas. The fossil fish is full of bones, verts and fins. The large worn bone is part of a pleisosaur paddle. The mosasaur vert has nice size and color.

The eggs were preserved standing up, vertically and obliquely in siltstone. Eggshells are very thin and smooth on the outer surface. The thickness of the eggshell is between 0.6 and 0.9 mm. The eggs are 105– 116 mm long and 36–48 mm wide. Possibly Prismatoolithus gebiensis Zhao & Li, 1993. Prismatoolithus eggs likely belonged to troodontids.

@doctor mud, Chris and I went off to a Cretaceous area on the South Island of New Zealand recently and found some amazing fossils. Between us we found paddle bones, shark teeth, petrified wood, a vertebrae and a few other bits. It was our first trip to this spot and had quite a bit of stuff to carry back, I needed help with my backpack as my legs weren't handling it My favourite find was the section of paddle with some associated paddle bones in it. I just finished the video and uploaded it here:

Hello everyone! I am looking for Squalicorax (Any species) to help aid in the research I am doing for my University. I'm looking for a bulk amount or Squalicorax hartwelli from Kansas, or anywhere in the Western Interior Seaway. I am also looking for Squalicorax falcatus from the Southern U.K., France, Belgium, and/or Morocco. Any complete or near-complete Squalicorax you have that you are willing to part with, please contact me. I am a college student. I have lots of shark teeth that I can trade, including: - Megalodon shark teeth and meg ancestors ( angustidens, chubutensis, obliquus, and Otodus minor from Russia) - Many Paleocene teeth from Russia - Paleozoic teeth including orthocanthus, xenocanthus, petalodus, etc. - Many Eocene teeth from Alabama and Kazakstan, especially Alabama. - Cretaceous species from Alabama, Texas, New Mexico, South Dakota, etc. - Australian miocene teeth - 2 incomplete Striatolamia macrota from Seymor Island, Antarctica. and much more. Please send me a PM on here. I am also collecting literature, and while I won't trade for literature, it would vastly help me! Thanks everyone, Chase

Had to split this into THREE posts: too many pictures! lol. My apologies for the large images; I thought they would be resizable once uploaded here. Will do better next time! PART I I honestly wasn't sure what to share for my first post here on TFF, but then I realized I just spent a week hitting my favorite (and some new) spots and decided maybe I'd make a post about that. I had to to pretty severely limit what images to include, and I apologize for not having a scale in each shot; I normally forget since I tend to shoot my finds just because I like the art of photography. The first location I decided to hunt is a pretty well-known one here in Texas. I've hunted the NSR in Fannin County multiple times over the past six months, always searching for a mosasaur vertebra; I have THE worst luck with good mosasaur finds! At the end of last summer I'd found one I had been told was digested (have since learned it may simply have been severely tumbled), and it was terribly ugly, so my search continued for another six months. On this most recent trip, I stumbled across not one, but three! Ironically, the very first one I found was the smallest one and I don't even think I realized what it was until I got home and looked at it; I initially thought it was just a chunk of random bone. The second one was more worn, but more about the size of what I was used to seeing posted online. The last one was enormous; it was so big and such an odd shape and color (from the red zone), that I hesitated even calling it a bone. I couldn't wait for some sort of ID, so I immediately posted images to the Dallas Paleo FB page and it was confirmed as a large, but shockingly worn mosasaur vert. Still, I was thrilled, even if they were all in rough shape! Beggars can't be choosers. These were some of the last things I found before I headed home, so it was great to end on a high note. Before all the vertebrae excitement, I found the usual assortment of things (along with other items not pictured, such as a couple of phosphatized clams and gastropods, pet wood, and bone fragments): Durania rudist, which I have always loved collecting, no matter how many I have. Ammonite fragment from the red zone. I have yet to find a complete ammonite from here, but I still enjoy the partials with suture marks. My first red zone baculites that still has a visible suture pattern! It's present on all sides. A day or two later, I visited a Pennsylvanian spot just west of Fort Worth. I've come to love this particular site, partly because it's a closer drive for me than most places, and partly because I had never heard of goniatites before I started hunting there a few months ago. I've been often enough at this point that I mainly focus on collecting the goniatite partials and the Tainoceras and Metacoceras nautiloid partials. I still pick up a random horn corals or gastropods if they are better than ones I've previously found, but I don't specifically look for them any more. This particular trip was quite interesting for two reasons: the paraconularia and a brachiopod. On my first visit or two to this location I was able to find a few paraconularia, but multiple trips after that produced none; most recently I stumbled across quite a few, and they were more complete than any I had found previously. As for the brachiopod, which I generally ignore, I spotted this Linoproductus half in the mud and could tell it was quite large, so I picked it up purely because of its size. It turned out to be quite beautiful and the only brachiopod I have displayed at home. I also got quite a tease. Right now one of the two top specimen on my "fossil bucket list" is a complete gonioloboceras; I realize this would be an incredibly lucky find, but I don't think I'll ever stop looking. Cephalpods are my favorite fossils. In any case, I managed to find a goniatite fragment that included both part of the top and the bottom and the center! I think I even laughed out loud when I found it. Maybe I'll just make a Frankenloboceras with all the pieces I have now! And, of course, the nautiloid pieces. [continued below]

Found this rocks on White Bay Beach in Northern Ireland, just a short drive away from the Giants Causeway. One looks like the cross-section of a Shell, but the others I have no idea. Any thoughts?

Hello. The following items remain in my "take it back to the lab to analyze" section of my findings. I have not been able to id any by looking thru books and online references. It just may be that they are nothing but unique patterned rocks. However, I do know I have at least one claw although I can't tell what it came from. Any help is always very appreciated. Did my best with the pics.. And thanks in advance.

Can you help me identify these fossils from the devil’s river area in Texas?
SolFire posted a topic in Fossil ID
My grandparents own land on the Devil’s River in west Texas and I’ve been hunting fossils with them there since I was six years old. When I was younger I thought that these might be fossilized dinosaur bones, but I doubt that now. My grandparents think that they’re plants but I also doubt that. I’ve been thinking maybe they’re some sort of tube worm, or a coral, but I have a feeling that they’re something I don’t know of at all. So, I figured it would be good to ask here with hope that someone will know more than we do. I read this morning that the devil’s river limestone is Cretaceous. The fossil in the bottom left of this picture is a nice cross section of what I’m interested in. The distinct segments or chambers remind me of the structure of an ammonite or a nautilus, which made me wonder if they could be a shelled cephalopod. They seem to be hollow (at least some of them): I found this piece today and was happy to see such a nice cross-section of the intricate wall structure:- 9 replies

So, as per my post in the Trips forum, i had a great time getting filthy in new jersey. These are the specimens i just dont know. Concretions? Bone frags? Teeth of something (salmon?) (one photo includes bivalves etc and i know those at least, its the other ? bits.. wild and crazy concretions at this site, good lord) Nothing easily identifiable to me, and i have a degree in this! Any thoughts appreciated

I took a vacation to NYC (and in good time too, since everything is going to hell in a handbasket) and on one day i went to big brook! I wore a full set of waders and crawled up, around, over, and through Big Brook for about 6 hours. It was great! I will definitely go back! Man, that site has some of the most convincing concretions i have ever seen, and i have seen a LOT! I know what much of i found was, but some is a definite mystery.

Hello, I've put teeth here for Id a couple of times and always received a satisfactory answer. I hope you can help me this time too. It is about this Ceratopsidae tooth from the Niobrara Formationn (Wyoming). Unfortunately no fossils of this group are known from this formation and I therefore wanted to ask you if you have any idea what species of dinosaurs the tooth could belong to. The tooth is 1,5cm in size. I hope if you can help me with this! Best regards from Germany!
