    Lee Creek Aurora NC Shark Tooth

    Found this tiny shark tooth in some Lee Creek matrix. Any ideas?
  2. Frightmares

    Aguja Formation Tooth ID

    Found this tooth in my Aguja Formation micro matrix. It's about 6mm in length. I know it's in really rough shape, and I actually broke it in half attempting to get pictures of the distal/mesial sides. Can anyone give me an idea of what it may be? Could it be a theropod tooth? I don't see any evidence of serrations on either side. Sorry if the pictures are not the best. It was extremely difficult to take pictures, especially after it broke in half. Base of tooth Distal Mesial

    Hadrosaur spit tooth?

    Found what I believe is a hadrosaur spit tooth as soon as I opened my bag of Aguja Formation micro matrix! Can anyone confirm?

    Aurora Micro Fossils

    Got a couple finds from my Lee Creek micro matrix that I could use some help IDing. I’m assuming the first one is some sort of ray or fish tooth. 1. 2.

    Rhincodon tooth? Aurora, NC

    Going through some Lee Creek micro matrix from the Aurora Fossil Museum, and I found what I believe may be a Rhincodon (whale shark) tooth. What do you guys think?

    Unknown NY Devonian

  8. The water level in a close by river has been the lowest I've seen in years... we're definitely experiencing a climate shift here in Central Texas. Even with some recent rains, the river is not regaining its normal levels. While that is indeed a sad state of affairs, it has made for some good fossil hunting....sooooo....Silver lining? I have found 6 little tiny outcrops of the blue grey mud that I recognize as Del Rio Formation, a great surprise when this area is typically Georgetown Formation and Glen Rose Formation. So of course, I dug up ALL OF IT that I could. I've been back three times and I think I got it all! Kinda sad that I got it all though. It has provided some great hours of Micro hunting! I finally bought myself a little camp shovel! It has proved invaluable! These little patches have yielded some amazing fossil. They are chock full of the cormatulid crinoid Roveocrinus signatus. These are all around 3 mm or 3/16 inch They are very varied: My other favorite thing to find are the myriad of crab claws, and occasionally was lucky to find both digits together. All of these are around 1/8 inch Another favorite is of course....starfish! While I have yet to find the actual central body of the brittlestar Ophiuria sp. , I have found LOTS of bits of legs and individual parts. Not much ammonite stuff, but I did find something quite special - this little fragment of Anisoceras sp. And this little unidentified ammonite. I did find one whorl of the heteromorph ammonite Mariella (which are common in other Del Rio outcrops) but it was not well enough preserved to merit adding. Also a couple of not very well preserved shark teeth- probably Leptostyrax And of course, lots of tiny gastropods! Probably a Fusus sp. Gyrodes biangulata Nerinea volana Cerithium texana Unknown Gastro probably a Turritella of some sort and not a fossil, but a nice little Pyrite rose

    Texas Cretaceous Micro Unknowns

    Hi y'all! A few little things that I would appreciate some help figuring out what they are! 1. Eagle Ford Formation Size aprox 1/4 inch. It looks like a tiny jaw? But I've not seen anything like this: 2. Another from the Eagle Ford Formation Size Aprox 1/8 inch 3. Aguja Formation Size Aprox 1/8 inch Seems fishy to me... 4. Wolfe City Formation Pretty sure is a fish tooth based on it being flattened, not round. But any ID of genus would be great. Size aprox 1/4 inch
  10. A few months ago I had the opportunity to collect a bunch of matrix from the Cretaceous aged (Campanian) Ozan Formation of North Texas in the "red beds". The larger fraction is rich in sharks teeth and other small macro fauna. After breaking down the matrix, I have put it through a number of sieves to facilitate picking and sorting. I have available lots of very fine matrix that made it through my 60 mesh sieve (so it is all smaller than 250 microns or ~0.25 mm). In this fraction I see lots of forams, some ostracods, and some other very small fossils. I am not really equipped to pick and analyze this small of material (and I have gallons of it) so: If anyone would like some, just let me know (PM me) and I will be happy to send you some. Again, this is very fine, I have not seen any sharks teeth in this size range but there are other identifiable fossils. In the US, I will be happy to send you a bag of it; if you are overseas, I may want some help with shipping costs or maybe we can do a swap of other matrix. If you have any questions, just let me know. Here is a quick picture of forams and some items I have picked out of the matrix offered (sorry for the lack of scale, but everything fit through 60 mesh).

    More Aurora NC Micro fossils for ID

    I have yet again more Aurora fossils that I can’t identify. I would appreciate any help with identifications, these should be the last of the unknowns and I’ll create a Member Collections post about my best finds but first it would be nice to know what these are. Sorry for no scale but the diameter of the circle surrounding most photos is 10mm. 1. This one is very odd, I have no idea. 2. Fish tooth I’m guessing. Can you tell what kind. I would not want to get bitten by it. 3. This one’s larger than most of the fish teeth, about 3-4mm It’s also more conical in shape. 4. Probably my largest non-shark tooth from here. Could it be Gator or Croc? 5. Completely clueless on this one. 6. Another unknown tooth. 7. Bryozoan I’m guessing, they can take all kinds of shapes. 8. Very odd shaped shark tooth. Not the typical capital T or triangle. 9. Another odd shark tooth, shaped like a claw. Reminds me of a whale shark tooth but something doesn’t seem right. 10. I’m not good with these teeth that aren’t in a typical anterior position. 11. Last one, same story as #10, it’s difficult to identify the teeth that aren’t “normal”. Thank you in advance. I appreciate any and all help and am willing to provide more photos of it assists in identification.
  12. I got a box of micro matrix from PaleoCris - Bone Valley Formation from Florida and I am STUNNED by the beautiful colors and preservation! I knew Bone Valley stuff was good...but wow. And he threw in some "extra" fossils of a nice big echinoid and a claw of some thing...maybe extinct armadillo. I still havn't gone through all the matrix, but wanted to show ya'll some of the nice stuff: All are around 1/8 inch - 1/4 inch This crazy Fish tooth plate - Labrodon sp. I think this is Baracuda? I love the little ray teeth Rhynchobatus. Sadly, this one leaped for freedom from my tweezers right after I photographed it. Gone gone. A pretty blue one Rhibobatus sp. Some Crab Claws I hope I find a whole sting ray tail spine. And of course...the SHARK TEETH! THE COLORS! And I am in no way confident in my ID on these teeth, so if you see something ID'd wrong, please let me know. Galeocerdo contortus Carcharhinus plumbeus Negaprion brevirostris Unsure of the ID on this one. If you know it, please enlighten me! Carcharhinus leucas Carcharhinus brachyurus

    Bone Valley Micro Matrix

    On my recent visit to search through Bone Valley material for megalodon teeth, I also was collect screened material to bring home to search in the Winter. I have been going through some and have been quite pleased. Here are a couple pics of my finds, I was wondering if the last 2 pics are a portion of a drumfish mouth plate? @MarcoSr
  14. I recently acquired some matrix via trade from @will stevenson. This matrix is from Hallencourt France. Just the second time we gotten to go through the entire process of breaking down matrix to a searchable form. I am still in the process of breaking it down and only have searched probably less than 20%. I wanted to begin the post now as I had a few minutes to write. The material is Early Campanian in age and from the North of France. Unlike my first experience breaking matrix down which was from a location with no publication, there is a publication. Sharks from the Late Cretaceous of France and England by Guinot, Underwood, Capetta, and Ward. There is an additional publication on the Batoids. The publication covers the Anglo-Paris Basin. Hallencourt has a pretty diverse fauna according to the paper and gives us an opportunity to explore Cretaceous micros from Europe for the first time. Most of what we got were pretty small pieces with 4 I’d call medium sized. It is very hard chalk and is pretty challenging to actually break down. It has given me the opportunity to experiment with different methods for breaking down matrix. I’ve used hot water treatments, vinegar and for the largest piece, freeze and thaw for the first time. It has been an exercise in patience lol It is also proving to be an invaluable experience going forward. We haven’t searched enough to really have a full sense of this particular matrix but the early results are mostly Chiloscyllium and Anomotodon. So far, 22 Chiloscyllium teeth and 11 Anomotodon though almost all are partial. Very few complete teeth except the Bamboo teeth. Most surprising find so far is easily a Synechodus. Only one tooth was found during the study according to the paper. We have also found Squalicorax (1), Carcharias (2), Scyliorhinus (1), Squatiscyllium (3) and our first ever Eoptolamna tooth ! There is A LOT of dermal denticles in this matrix and at least 5 distinct types. We also found one small Shark vert. Its a grind. Quite a bit of work. Way less dense in shark teeth than our Mesaverde stuff was and not real diverse so far but there is a lot of searching left to do. The lack of density does make any find pretty cool though. I will update this with better pictures after everything is completed and I have the final results. I’d like to thank Will for the trade that brought the matrix. Very cool TFF Member!!!! 1st pic the bag of matrix before breaking down 2nd pic Anomotodon hermani 3rd pic a slide with a few of the finds
  15. Howdy! I recently went to Post Oak creek, and ended up with more matrix than I can immediately use. Rather than let it sit unsearched, I figured it was worth a shot to post some up for trade here. Each bag has a pound of material in it, and they have proved to be very productive. I’ve found numerous ptychodus teeth, a (poorly preserved) lobster carapace, shark and fish vertebra, various bones, coprolites, and of course, lots of other shark teeth. So there’s lots of different things that can be found. I’ve got around 25-30 lbs I’d be willing to trade. I am primarily interested in vertebrate material, but I’ll also look at ammonites, and really anything else since I’ve finally gotten back into collecting again.
