  1. Fish/Skate Teeth ID Help

    Hi. Found some neat stuff in the Lee Creek Matrix today. I believe most of it is fish/skate teeth. If anyone get help with ID it would be much appreciated. Everything is 1 - 2mm. Also, Can somone explain how to get of the dirt on these teeth? I soaked them in hot water and some of it came off. They are so tiny to scrub. What would be safe to soak them in? Thank you for any feedback! I believe these two teeth are Rhynchobatus Teeth #1 #2 #3 I think this is some type of skate tooth but not sure what type #4 absolutely no clue #5 I believe this is a fish tooth
  2. Shell?

    Hi. I have no idea where to even begin with this one. Just found this in the Lee Creek matrix that I have been working through the past month. This one is 1MM. My uneducated guess is..... nevermind I have absolutely no clue! Anyone's guess would be better than mine. Thanks for any feedback. Mark
  3. Fish or Shark Tooth?

    I found these two teeth that are somewhat similiar. I was thinking more of shark tooth than fish but I am not sure. It is just over 1MM. Thanks for any feedback. Tooth#1 Tooth#2
  4. Unique Shark Tooth

    Hi. Found this crazy shaped tooth this morning going through Lee Creek matrix under a micrscope. Never saw anything like it before. Hopefully someone has seen this before. Looks to be slightly over 2MM. Thank you in advance for any feedback.
  5. Mini slab with macro fossils, maybe?

    I have this little slap I polished a awhile ago, it has some really interesting critters on it. Even a micro jaw bone with teeth maybe? Has many interesting things on it, I have just taken pictures of a few. Green arrows point out the "jaw" and a few other things. The "jaw" is the biggest at a whopping 40mm.
  6. Micro Fish (?) Tooth

    I found this - almost missed this - while sifting through some micro matrix today. I'm guessing some sort of fish tooth, but can anyone confirm? From Aurora Fossil Museum, Aurora, North Carolina. Lower to middle Miocene from the Pungo River Fm. It's so small that I have a hard time getting the camera to focus and my microscope cam just made it a big, black blob, so I apologize for the soft focus. That course rug it's sitting on is a piece of fine velvet!
  7. Is this another denticle?

    I could use some help with the ID of this ornate little find from the Cookie Cutter matrix from Florida. I have considered ray tooth and shark or ray dermal denticles...@Al Dente @MarcoSr Thanks for looking.
  8. Micro print fossils

    Found sifting through little flinty pebbles on South Isle of Wight beaches First, which I am most interested in, was actually found by my landlord. He just picked it up saying "a stone in a stone" but I noticed some striations coming out of the hole. So took it home and pulled the smaller stone out and you can see a teardrop shaped impression with radial striation and pimple markings. Impression is 10mm long by 6mm wide. Second is just a band of tiny circlish markings 3.5x2mm. Third is a little hole with vertical ridges, probably nothing. 4.5x2.5mm And finally a nice echinoid print. I've found something similar years ago and someone posted an even more similar picture of a Temnocidaris species so I'm sure that it's something like that. Area of clearest three circles 6.5x4mm
  9. small patterned fossil?

    Like most of what I find these days, this is small (the scalemarks are mm). A small cylinder with diagonal pattern of markings. Seems too solid for fossil cartilage or skin? Any ideas?
  10. Tiny tooth ID needed

    I have a tooth here from some micro material from SE North Carolina, its mixed Eocene ( Castle Hayne Form.) and maastrichtian (Peedee Form.) It was suggested that maybe its a symphyseal ? Does anyone have an idea from what? There does not appear to be a nutrient groove, but it is only 4mm. Thanks for your help.
  11. Toothed Jaw Bone ?

    Hello All, I was picking through some micro material from SE North Carolina, its a mix of Maastrichtian (Peedee Form.) and Eocene ( Castle Hayne Form.). I found what looks like a tiny ( 7mm long) jaw bone with teeth. If it is a jaw bone , is it a tiny reptile or a bony fish ? Or perhaps it is neither but something else. Thanks for your help.
  12. I was sorting thru prior finds from Cookie Cutter creek when I came across this tiny osteoderm that I must not have identified at the time. Am I wrong, or is this the most minuscule Armadillo osteoderm ever?! What else could it be? Can it be ID'd to species? It really is only 2 1/2mm.
  13. Hello all! A few weeks ago, @caldigger generously sent me some micromatrix from Sharktooth Hill/Bakersfield in California (Miocene in age), and there is one little fossil that is kind of weird - hopefully someone can help me identify it! It's smooth on one side and has sharp bumps on the other side - please feel free to let me know what you think it might be. If better pictures are required, we'll have to wait until I get some sunlight up here in Mississauga - hopefully soon! Thanks in advance!

  14. images of amoeba on rock?

    these are better images of my earlier images that were to blurry.
  15. images of amoeba on rock?

    Several clear images of different shapes on a rock that is about 1 inch in diameter. Found exploring on oustkirts of Las Vegas, NV. Are those images Amoebas? Cretaceous Period? I'm new here, so I hope I did this post correctly. Thanks for any input!
  16. ID strange micro marine colony

    I don't have a clue as to what these tiny things really are. These were found inside of a sandstone boulder that was broken apart, which was full of marine fossils. The size of the entire area seen in the first photo is about 8mm x 10mm and 0.50mm thick. I'm having a very difficult time wrapping my brains around what I'm looking at here, all of those tiny white dots appear to be embedded in some sort of resin-like material and connected by a web-like structure. That web-like structure is very similar to what you see with bryozoans, diatoms and radiolarians but I can not find anything that looks like these things. Anyone have any ideal as to what these things really are?????
  17. Possible micro mandible found.

    Hello member of TFF. I finally got a chance to really dig (sort of pun intended) into some matrix I bought back in December of 2013 from I believe tj102569 (but it's been so long I cannot find the sale post anymore). If I remember correctly the matrix was from a quarry in possibly Grant county South Dakota. But it was definitely from a quarry in South Dakota (yeah I know there are more than one). The matrix is pretty hard. Engraver and dental pick don't do much more than scratch the stuff. The seller at the time said he used a hammer to just break it open and find sharks teeth. But I was after large and micro fossils so I didn't like that path. I started to use regular 3% peroxide with a small amount of success and combined with the engraver found a few things, but not as well as I would like. So I store the matrix away until I could find a better solution. Flash forward to now in my new prep room and some 12% food grade peroxide and I get results I like. The 12% really breaks down some matrix. Word of warning though I measured temps of 167.4 Fahrenheit so if you chose this method be sure to use containers that are good with cooking temps (old food grade containers are what I use). Anyway low and behold I believe I have found a mandible. But it broke on me as I was picking it up with tweezers. What do you think? And this is the starter matrix. Thanks for your help.
  18. Micro fossil?

    Does anyone know what's this could be? it's form Purbeck Group matrix form UK
  19. In 2006, University of South Florida student Mike Meyer found the beads during a summer project in the field, working with Florida Museum of Natural History invertebrate paleontology collections Director Roger Portell. Very Interesting!
  20. To Rumi: Thanks for the ID of the elphidium ...The specimen in the last post was the largest I came across, it was about 1.5mm, all the rest are well less than 1mm. Are these smaller ones in this post of the same species? Thanks....
  21. Micro teeth? Not sure

    Found in Atco formation in Texas, Coniacian age. Looking in my Welton Farish book and I can’t find anything similar. Maybe spines of some sort? Kind of looks like teeth and kind of not. Lost on this one. Scale is in mm.
  22. Found this digging through my micro gravel. It comes from the late Cretaceous, bottom of the Austin chalk, top of Eagle ford, Atco formation area. It is 3mm in length and I would say 1ish in width. Internal mold of something, crustacean maybe? Really not sure.
  23. Rainy day today, so here are a few of my micro finds. Mostly they are from Post Oak Creek, a few from the North Sulphur River, and a few from a location somewhere between the bottom of the Eagle Ford and top of the Woodbine. All are late Cretaceous and all are microscope pics, either 10x or 60x. Sorry some do not have any objects for scale. A piece of coprolite from the North Sulphur River with some fish verts, possible Ptychodus tooth, and mystery shiny stuff:
  24. Micro fish tooth Cretaceous

    Any ideas on this one? Found at the bottom of the Eagle Ford/ top of Woodbine. It is 4mm long and 1.5mm wide. Found on a slab with lots of fish parts.
  25. micro bone and claw?

    found in gravel from Brazos river here in west Houston it appears to be a very tiny claw but will let the more experienced determine also there is what appears to be a small bone also took a pic of it with micro scope camera. I guess another possibility could be a tiny tooth?
