  1. Another coprolite for consideration

    Here is another of the many coprolites that I have been finding in Sacha's Merritt Island matrix. I haven't focused on these too much, being more intrigued by the bones. But with all of Lori's interesting threads on coprolite lately, I figured that I would put this one out there. Many of the coprolites in this matrix resemble this one. Sometimes I can see tiny bones in them, often not. I am curious what animal these are from. Most of my finds are terrestrial, with an occasional fish otolith or vertebra. So, @GeschWhat and @Carl et al., what do you think?
  2. New Jersey Cretaceous unknown

    I recently found this tiny fossil around the Big Brook area of the Monmouth County NJ Cretaceous. I really have no idea what it is. I believe it to be fossilized and under a loop it appears to show what looks like bone structure but other that, I'm stumped. Any idea what it is? Thanks! -Frank
  3. I found a nice little assortment of micro shark teeth today in the North Sulphur River in Ladonia, Texas. These were found about 3 feet up in the wall of the bank. Anyone know what type of sharks these are? There’s also a little round black unidentified object. I thought it might be a tiny fish very, but unsure about that.
  4. Caloosahatchee Micro Gastropods

    Hi, Just thought I would show some examples of the micro gastropds that are found in the Caloosahatchee fm of Florida. They all come from sieving the contents of larger shells and are between 2 and 8mm. Caecum coronellum Caecum floridanum Caecum imbricatum Cyclostremiscus dartschi Cyclostemiscus sp. Solariorbis funiculus Mioceras sp Kurtziella limonitella margaritifera Cadulus quadridentatus
  5. Bone valley teeth

    I recently got some bone valley matrix (thanks @joshuajbelanger) and over my first search I found these, and I am horrid at identifying shark teeth, do you all know what they are? They are all around one millimeter in size. Thanks!
  6. Rattlesnake Creek micro

    Being the good dude that he is, @Jakuzi gave me a bag of some of the micros from Rattlesnake Creek that he had traded some POC micros for. I finished up the RSC bag today and found this nugget. Any clue what it is? I definitely have no clue.
  7. Any ideas what is in this matrix?

    Noob here. We tried our luck near Andalusia, but as expected the water was too high. We ended up in Sepulga River and this was all we walked away with, but still curious what might be here. There were lots of new mollusks strewn about and I grabbed these just as a MASSIVE huntsman spider chased me off.
  8. Microfossils

    I'm currently working on an oil rig in the Bay Of Campeche off the coast of Mexico. We currently have 5 paleontologist on board sampling micro fossils that are brought up when drilling. I had a chance today to look at some amazing specimens under a microscope. I wish I had pics but cameras are banned here. I got to see many types of Foraminifera that resemble the ammonties I collect. They were quite impressed when I showed them some of my Cretaceous finds from NSR.
  9. Kids Club Micro-Fossil Hunt!

    So I didn't know where to post this, but figured fossil hunting trips would be a good spot since the kids were doing an indoor fossil hunt! Today I did my annual class for the Western Interior Paleontological Society (WIPS) Kids Club. It is always a hit, but due to scheduling I was unable to make the February class and did this one in May. May tends to be a smaller group because of the nice weather and vacations, but we still had a great time! The adults even wanted to get in on this activity and I was more than happy to help! The worst thing that happened was I forgot to take lots of pictures! I took (2) 5 gallon buckets of matrix, one bucket from Peace River, FL and the second bucket from Aurora, NC. I talked to the kids about how fossils in different locations can be similar (ie. shark teeth!) and we explained the importance of labeling your finds! Each person was given (1) 5-ounce cup of matrix from Peace River, and (1) 5-ounce cup of matrix from Aurora. We set up microscopes and laptops an allowed the kids to photograph their 5 favourite finds. We set out books, posters, and print outs to help with the identification part. They then loaded these photos on to a USB and have some very nice detailed photos to take home with all of their finds. That's right, I let them keep EVERYTHING! One kid found a cookie cutter tooth, full root and all! I don't even have one in my collection yet! Aside from keeping everything they found I made sure to send each kid home with a small 125mL bag of each matrix, and 5 various fossils from my Peace River hunting trips ((3) 25mm+ shark teeth, a dugong rib, and a turtle piece.) I shared with them my preferred methods of hunting and encouraged them to try their own! All in all it was a great day with lots of very nice finds! Thanks again to @Sacha for sending me Peace River matrix for my classes!
  10. Bone valley FL

    Going back through some of the material received earlier this month in a trade and continue to find some small items. Most I can identify but need some assistance on these.
  11. Tooth or Scale

    While sieving micro material from my favourite spot I came across this small specimen. It is 3.5 mm at the longest side so not very big. There is a distinct shine on one side so a first I tended to think tooth but I am unsure. Part of me wants to think it is a tooth from some type of parrot fish. The more logical part of me tends to think it is a fish scale of some type with the end broken off. Due to size I can not tell if the end is broken or complete except for a little wear. At the moment I am open to opinions as to what the micro fossil is With the photo I will go with fish scale? Mike D'Arcy
  12. E. parvus

    This tiny echinoid; 6.21 mm by 4.31 mm is extremely large for the species. Most range between 2 and 4 millimeter. The measurements were taken while taking pictures with my digital microscope. They are an uncommon find by most collectors. Seeing them in situ is extremely difficult unless the sediments have been very well weathered. Most I have found are from matrix I collected. The last picture of the 2 is meant to show the size range of these. The smaller one measures 2.68 mm long by 1.74 mm wide; and I have a few even smaller.
  13. Shark Tooth Hill Micros

    First off, I want to thank Doren for sending me a small flat rate box full of STH matrix for me to try sifting through. I still have quite a bit of fine matrix to sort through but already I've managed to find hundreds of specimens. I've found quite a few Carcharhinus, Cetorhinus, Galeorhinus, Squalus, and tons of ray teeth. When I'm finished with all the matrix, I think I'll write a follow-up post with all the nice specimens I found. I'm having a little trouble identifying various species of rays - maybe someone has a literature suggestion to help me get familiar with different tooth characteristics? From what I can tell from other posts, the features that differentiate some ray species are quite subtle and to my untrained eye, very difficult to distinguish. I wouldn't mind some ID help with these teeth in particular. Scale to the right is in mm. If you could also comment on how common/uncommon these species are and what position they are in the jaw that would be immensely helpful as well. Also, maybe someone wouldn't mind making a list of the species found at STH and rank how common they are? Also, does anyone have suggestions for removing the last bit of silt/sand from the crevices in the teeth? I've tried water and gently stirring but that does not have much of an effect. Thanks for your help!
  14. Lance Formation Micro Tooth

    I have some Lance formation matrix I purchased on that auction site and I have been slowly breaking it down. This is one of my finds. I don't have a scale small enough to measure it against so . . . It is a little smaller than the head of a pin, flea speck. I did a Google image search on Lance Formation micro teeth but came up with nothing. The photos were taken with my Nikon point an shoot through the eyepiece of my microscope. These photos are the best I can do.
  15. I was shopping at Menards this morning and found this nice plastic / portable / collapsible strainer with appr. 3 mm holes. This strainer is light weight, has handles and appears that it would work nice for Micros- and at $6.99, you can't beat it.
  16. I have some rattlesnake creek micro matrix for trade( 1/4" and smaller). I am open to any trades of something I can't get here in Gainesville. I have a bunch about a gallon worth and some to dry still. The pics are from 1 cup worth. I quickly went through. I know I left some was getting tired and my kids helped. Sorry US only international cost to much. Also willing to trade for rocks and minerals, for my daughter she got a small set at school and looks threw them daily trying to ID them. lol
  17. I just came across this article and thought it was very interesting. I hope it's okay to post the link. I also realize it's old. I had never given much thought to what a grain of sand looks like. Some of it looks like the specimens I've seen on here, only microscopic. Makes me want to check out my local beach and find a high powered microscope. http://www.boredpanda.com/magnified-sand-grains-microscope-photography-dr-gary-greenberg/?media_id=sand-grains-under-microscope-gary-greenberg-4
  18. polished dinosaur bone

    Hello again, Last year I found this chunck of dinosaur leg bone in the Boulonnais, North of France. Jurassic sediments. See this topic: I just polished a small piece and I am very happy with the result. I made a comparison with a picture from the internet of a duck-billed dinosaur on the left and my piece on the right. You can see the growth lines! source: http://scienceblogs.com/notrocketscience/2008/08/06/duckbilled-dinosaur-defended-itself-by-outgrowing-predators/
  19. A fellow TFF member gave me some micro material from the Eocene, Meridian Mississippi . I don't know much about micro fossils so was hoping to get some info on the following? Which were all photographed next to a US nickel. photos 1 and 2
  20. STH micro Bakersfield tooth

    hey guys, found this interesting little tooth while sorting some STH matrix. Any clue who it belongs to? Or what tooth it is?
  21. micro fish jaw?

    Any ideas on what this is? It comes from an estuarine upper Cretaceous formation in Eastern Mississippi. The first photo shows the tip of a needle. I'm new to micro paleo and finding it fascinating.
  22. ID help on ?mammal? Teeth?

    Hey all, here are four different examples of what I believe to be teeth from the same species. To me they appear to be herbivore grinding teeth or omnivore molars. Any ideas? thanks!!
  23. My kids and I sorted through some gravel that had been given to us by a friend, from a creek that is south of the North Sulphur on private land. Here is a video of some of the finds: And here are some photos, verts first:
  24. Examining a piece of slate that I had split, I came across what I thought were some crystal formation & veins. Checked it out under a low power stereo dissecting microscope & I started thinking that this might be fossil remains of pollen & small stem or some other plant parts. Put the sample under my compound microscope with a digital camera. Attached are some photos. All are at 100x with overhead oblique lighting. To make this more interesting, I don't recall where I "captured" this rock. I would thing somewhere relatively local, central Maryland, south central Pennsylvania. Sure would appreciate some thoughts & comments.
  25. Some Micro-Fossils From Sharktooth Hill

    I spent a few days hunting teeth at the Ernst Quarries of Sharktooth Hill. The hunting was plentiful for the standard Miocene fossils, but I also brought home a few bags of sediment for micro. It took a while to go through, catalog and photograph, but I have the results. There is such a wonderful variety in this sediment! Here are a few of my favorites. All are shown on a millimeter scale. I will be presenting the fossils from this hunt and a previous hunt at the April meeting of the Dallas Paleontological Society, along with tools and techniques for hunting at Sharktooth Hill. Pics below include: Galeorhinus Triakis Dermal Denticles Catshark Heterodont Anterior Heterodont Posterior Triakidae (Smooth Hound Shark) Bony Fish Teeth
