  4. So Many Minis!

    From the album Aurora/Lee Creek Mine Micro Matrix

    This assemblage came from one cup (about 340 ml) of micro matrix from Aurora Fossil Museum. Oddly, they are generally much larger than most of what I found in the rest of the matrix. They are all from either the Pliocene or Pleistocene. See album description.

  7. This is a completely new area of interest for me, but I find scanning for microfossils addictive. I got some vinegar and plan on processing some beach rocks (East Central Florida) that I picked up because I could see easily see some small fossils on the surface and assumed there would also be micro fossils inside. I crushed a few small samples, which did reveal more microfossils. Mostly what I could identify are broken bits of bones, but I'm sure there is much more that I'm missing. There is one object I found very interesting and beautiful, however I don't know what it is. I would like to know what you think the first object might be. That object is still attached to the matrix. The other object I found in the same sample. Both were revealed after breaking the sample. The first item is about 1/8th inch long but very narrow, and from some angles appears to be a hollow tube. The next object appears to be bone and is only about 2.5 mm wide and long. Thanks.
  8. What is a micro?

    Good morning. Is there an accepted demarcation of what constitutes a micro? Is it 1/4 inch or smaller? These two Crows are 5/16 inches. The other photo is, I think, just a cusp which is 1/8 inch. Thanks all.
  9. I picked up a nice chunk of conglomerate that had an obvious fossil tooth embedded in it, but became interested in what small micro fossils might be in it. I experimented with a small piece of fossil bearing rock and found that the acid destroyed the fossils amost as much as the rock, so as a result I turned to just doing surface scans. I eventually decided to remove one surface micro fossil that seemed to be pretty much on the surface of the conglomerate. The results were satsifactory, but I don't know what the micro fossil is. It is roughly one mm in diameter and maybe half a mm thick. It is small enough that it stretched my limits and the limits of my imaging system. I think it could be a fish tooth or scale, but have no idea. It definitely has some form and detail to it. I don't think it is just a broken piece. The first two photos show the item still attached to the conglomerate. One photo shows a bit of conglomerate still attached to one side. For size, the one line you see is .5 mm in thickness. I consider it a success simply because I was able to extricate one small fossil from conglomerate and get some photos. If it is actually something identifiable, I'd be doubly happy. Thanks to all.
  10. While I have been out fossil hunting a bit in the Texas Summertime heat I am still having great fun with the Micro Matrix- it sure is pleasant to sit in the AC and poke about for fossils! I had some great little finds in the Mineral Wells matrix, but i am just amazed by the Bridgeport matrix. Even though it's still Pennsylvanian, it's very different from the MIneral Wells stuff! Different formations and all..... What's really neat about the Bridgeport matrix is firstly - it's bigger, typically. and secondly...it's COLORFUL! Reds and golds and purply browns and oranges. It's really lovely stuff!! Here are some of my favorites from the Jasper Creek formation. : First the Echinoid bits - I love these little "cat ghost" plates. 2 mm Most of the spines were incomplete, but I found a nice base and a nice spine, just not all one piece 7mm base and 1 cm spine A funky Echinoid plate 7 mm So many neat Crinoid fragements - arms, cup fragements, columnals, etc! All of these are aprox 5-8 mm except the first one which is a honking 1.5 cm. ) And this crazy crinoid spine that was broken and was regenerating before it died...hence the "dimple" on the end. Thanks fellow Forum Members for helping with that ID! 1 cm Love this crinoid column...I think it's my favorite. It's so Art Deco.....about 3 million years early. 1 cm Some other nice/ interesting finds Neospirifer Brachiopod 5 mm Not sure what this is...I assume a brachiopod. 5 mm Colorful Bryzoans 4 mm Bryzoan on a Crinoid 8 mm Girtycoelia sponges Each are aprox 5-8 mm Gastropods: Pseudozygopleura 4mm Possilbly a Phymataopleura? Not sure of ID 5 mm Possibly Goniasma? 5mm And then there's this thing......a bryzoan encrusting a sponge! 1 cm
  11. I hesitate to post this because I know next to nothing and don't know if it is worth posting, but I picked up what I would call a conglomerate one day on a Florida beach near Jensen Florida primarily because of a fossil tooth that was in the conglomerate. I could see a few other bits of bone as well. But I got to looking at the conglomerate with my microscope and saw what I thought were some nice small but interesting things. I suspect that the conglomerate is not very old and don't think there is likely anything much older than the tooth in the conglomerate except possibly some small shells, which I tried to photograph. I was thinking of dissolving this conglomerate but didn't want to destroy the shells, some of which were crystalized. I decided to try dissolving a smaller piece that I had which showed only what looked like bits of bone and had few if any shells. Here is the kind of thing that I saw in the big conglomerate that I've not decided if I would try to dissolve. What do you think? Does it look like anything old or interesting might be in this clump or do you think I would more likely to destroy some of the nicer things (if you think there might be any at all) by dissolving this clump? I'll post photos of some of the things that stuck out to me even though most were .1 cm or less. A few were slightly larger. And a a few a lot smaller. First the conglomerate showing the brown tooth, which is about .75 inches square. Then some of the much smaller things I thought were nice. The last is my favorite. Appears to be maybe a piece of coral or stem. What do you think? Thanks to all. Sorry if this is just waste of space.
  12. Nj Cretaceous micro shark tooth id

    If anyone can help I’d please,thanks
  13. Pennsylvanian unknown microfossil

    I found this small specimen while splitting some Pennsylvanian black shale today. As usual, I'm not sure what it is. Looks like a jaw to me but I really don't know. It measures about 5mm long. Any thoughts? @jdp @RCFossils @deutscheben
  14. tiny piece of jaw

    I was given this very small piece of ?mandibular bone. Any help would be appreciated in id. it is approximately 12-14 mm in length, 4 mm in height and maybe 2 mm on the dental surface from the hells creek formation in montana.
  15. 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
  16. 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
  17. 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
  18. 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.
  19. 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.
  20. 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!
  21. 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.
  22. 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
  23. 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?
  24. 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.
  25. 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.
