  1. Possible tooth?

    Got some micro fossil matrix from the Inglis fm in Yankeetown, FL yesterday & was poking around in it. Found several flat disc's (echinoids), a few tiny urchins, urchin spines & this oddity. I think it's a tooth, but from what I have no idea. Just over 5 mm in length, very glossy & slick which made it hard to pick out of the matrix & kinda beautiful. Not sure what to make of it, but I'm hoping the folk's here can. Looks like it may be a frontal tooth, if it is a tooth. The marks on the ruler in pic 1 are mm.
  2. Merritt Island mystery #8

    Hey is another mystery found in Sacha's Merritt Island, Florida Pleistocene matrix. I don't have a clue how to classify this one. The image shows 3 views if the same piece on the left, and 2 separate bits on the right. I can't tell if these fit together or not. Note the puckered hollows and the blue translucent bumps which are actually that colour! This is one of the strangest things to come out of this matrix. Any ideas?
  3. For an upcoming trip to Florida, I decided to buy an item that I have been looking at for some time. It is a %- Piece 13 1/4" Stackable Sifting Pans. These pans fit very nice on top of a 5-Gallon bucket and come in the following sizes: 1/2" , 1/4" , 1/8" , 1/12" and 1/20". I believe that I will only be using the first 3 sizes, but it was cheaper to buy them in a set ($49.44) versus buying them individually. Can't wait to try them out. 1/2" Size 1/4" Size 1/8" Size 1/12" Size 1/20" Size
  4. These finds are from a shelly matrix collected by TFF member Sacha from a spoil pile in the Indian River near Merritt Island, Florida. As we enter a new calendar year, I realize that I have been working on this matrix for over two years! Lest anyone think that I haven't been absorbed in this matrix all this time, I am posting an image to illustrate how I am cataloging my finds. For now, I am sorting like with like, and attempting to ID the similar items as I go. Now, if I just didn't have to go to work I would be a lot closer to completing my work on this! LOL This picture shows some of the insectivore finds including; bat, mole, and shrew teeth. 'J' and 'K' are lower and upper shrew incisors. I'll try to post more images like this as I go in this new year. Thanks for looking, Julianna
  5. Insectivore ID

    I had another 'Ah Ha' moment when I recognized a fossil that I've had for some time in a paper that I was studying. At one point I had posted 'K', but came up empty. Fish tooth was suggested, and I moved on. I also have collected several of 'J' and thought they were some kind of claw. Now I know that J and K are lower and upper incisors respectively of a shrew! I looked at many more papers online and am satisfied that my ID is correct (even if many of them refer to European species of Soricidae.) Here is the image of my finds followed by a page from one of the papers. New data on Eulipotyphla (Insectivora, Mammalia) from the Late Miocene to the Middle Pleistocene of Ukraine Journal of Vertebrate Paleontology 30(2):535–546, March 2010 © 2010 by the Society of Vertebrate Paleontology ARTICLE SORICIDAE (SORICOMORPHA, MAMMALIA) FROM THE PLIOCENE OF TOLLO DE CHICLANA (GUADIX BASIN, SOUTHERN SPAIN)
  6. Bird or bat bone?

    This small, fragile bone was found in Sacha's Merritt Island matrix. I think that it might be an ulna. I spent hours looking at pictures of both avian and bat bones, and cannot be sure which it is. Is my photo and the bone's condition enough to identify the bone? Thanks for looking.
  7. Is this a coprolite?

    This lump of cemented bones came out of Sacha's Merritt Island matrix. Does it look like it could be a coprolite?
  8. Humerus for ID

    When I found this humerus in Sacha's Merritt Island matrix (aka Frog Toe matrix), I remembered a post from @Harry Pristis regarding the EECF of a similar bone. http://www.thefossilforum.com/index.php?/topic/67182-miocene-mystery-bone/#comment-705462 I wonder if it can be ID'd further. If the entepicondylar foramen is present in opossums, shrews, moles, mustelids, and raccoons, those are the possibilities to consider. I think that it is too large to belong to a shrew and too gracile to be that of a mole. If from a raccoon or opossum, it would have to be a very young one. So that leaves a very small skunk or a weasel. I am leaning towards a weasel, but would love to have confirmation. Is the bone too beat up to ID?
  9. Small Pleistocene bone for ID

    As I continue my study of the micro matrix from a spoil island in the Indian River of Florida, there are a few bones that I can't seem to place. I am not sure where in the skeleton these belong, (much less whose skeleton!) I have found half a dozen of these, all about the same size. I can't make a match in any of my books...nor my online searches. I will probably do a faceplant when I get the answer, but I am ready am ready! Thanks for looking.
  10. Another Merritt Island mystery solved

    I posted this Pleistocene fossil last week. I found it in TFF member Sacha's Florida micro matrix from a spoil island in the Indian River. I could not find a match in any of my books, but I did find it in a PDF! I don't know that it is the species that I selected to compare, but I am happy to call it 'snake'. The 'unknown' that I originally posted: The match that I found: The figure that I found:
  11. is this a bird coracoid?

    I found this in Sacha's 'frog toe' matrix from the Indian River spoil island in Florida. It is from the Pleistocene Melbourne bone bed. I recognized a similar bone in one of my books. Is it from a bird? If so, can it be ID to family/genus even? Auspex? Thanks for looking
  12. Unusual Bone For I D

    I found this tiny bone in Sacha's matrix from a spoil island in the Indian River near Merritt Island, Fl. I have included several views. This one was tough to photograph. It is difficult to see in my photos, but there is a small perforation in the scoop like end. The only thing that I can think of is maybe a mouse baculum. Any help on this one would be appreciated.
  13. Amphibian, Reptile, Or Just Crabby?

    I just received a small flat-rate box of Jcbshark's (jeff's) World famous cookie cutter matrix today. And I found some free time to sort through it. I found two partial cookie cutter teeth and lots of the same ol' stuff. For some strange reason every time I've sifted this matrix it is filled with Drum teeth, and is surprisingly devoid of the usual suspects....... shark teeth. I also found a few strange pieces that i may ask for help a bit later. And im sorry in advance for the cell phone pics, but the miniature nature of micros/macros pushes the limits of my outdated smartphone. The spiney texture reminds me of Permian sharks denticles i have found. But obviously this is far from Permian material.... It also looks slightly reptilian/amphibian to me. Idk......? My gut says crab material. Any help is appreciated. Thanks. Scale is in millimeters.
  14. The 2nd week in June has passed and right on schedule the rainy season has begun in earnest for most of Florida. The rivers in the Central and Southern parts of the state have risen rapidly, but the northern Florida and Southern Georgia rivers haven't yet fallen enough, which they frequently do during an average year. With El Nino forming up, we should get a better chance of those rivers staying down some of the summer. So while water in the rivers were high, and today was a beautiful day, I went to Yankeetown, on the Gulf of Mexico at the mouth of the Withlacoochee River. This is the site where I collect Eocene micro matrix from the Ocala Limestone dredgings on the spoil islands and surface pick Echinoids. No wind, no clouds and no rain yet. This is a pretty long drive for me so I wanted to collect as much matrix as I could while I was here. I must have looked fairly beat because my friends kept an eye on me most of the morning, It will take a while to dry all the matrix I collected, but this supply should last a while. I still have allot of Peace River matrix I collected last month before the water came up. If there are any FF members that have not looked at either of these, I'll put an offer out later this month or next. Next week I'm hoping the water level continues to drop in the North Withlacoochee River in Georgia. I very much want to get back there to get another batch of agatized coral. I may get a small sample of matrix from there as well to see if it has anything to offer. On the macro level, the only fossil life form that is apparent is the coral itself, but since I'm going anyway, I'll give it a shot. Hope your spring was great and your summer is amazing!
  15. My wife Tammy and I made it out for one last trip to the Peace River for this season. I expect I'll be busy and won't have a chance to get back to the river before the summer rains usher in another rainy season with raging river levels depositing a new layer of gravel (and erasing any of the pot holes and spoil piles that us fossil hunters have worked so hard at this season--like shaking a giant Etch a Sketch). We experimented with a 1/2" mesh retrofit on one of our sifting screens since John (Sasha) and Jeff (jcbshark) have used them to great end. The spot we focused on in the Peace River was an area of large chunky gravel with bowling ball size boulders of matrix mixed in. This gravel bed has never turned up much in the way of smaller finds or tiny shark teeth so we figured we'd not be missing much with the wider screen mesh. As Jeff had commented on, you sure can shovel a lot of material through the wider mesh before filling a screen. I went from an average of 3 shovels full per screen (with the 1/4" mesh) to 6-10 shovels with the more coarse mesh. As there is a lot less tiny gravel to sort through in the sifter it takes very little time to parse through what the screen has kept from passing through. It was definitely a quick way to zip through a large amount of gravel. The very first screen produced a nice Equus lower molar which was a nice way to start the day. Though this site has produced some interesting finds in the past (a couple of 3 lb. mammoth tooth chunks, large makos, glyptodont rosettes, and even a gold wedding ring and tie tack--there must be a story there) this trip didn't produce much in the way of "wow" moments. The water was over 2' lower than when we tried this site just two weeks ago so it was much easier to dig and even visually locate the chunky gravel areas. Since I'd found large chunks of mammoth tooth there in the past it seemed necessary to reach down and inspect every large chunk that wouldn't balance on the shovel on its way to the sifter. Sadly we only had large chunks of matrix and no heart-stopping moment when a large, intact mammoth tooth reveals itself from the tannic waters--maybe next season. Though we hunted alone this weekend without the company of any of the South Florida TFF members, we did have a companion of sorts. While standing in waist deep water about 20' from the shore where our canoe was parked I looked out while chucking larger pieces of matrix away from our digging area. Just after a shoebox size chunk of rock had left my hands I noticed it was heading in the vicinity of a young gator which had come to the surface for air (and likely to see what all the commotion was about). Though the rock created a great depth charge of a splash not 3 feet from the gator's head it didn't spook but simply slowly descended back into the tea colored water. Had this been a 13' adult I'd have given it as wide a berth as possible as I cautiously slinked back to my canoe but as this was a juvenile probably less than 4' I chose to keep my eye on him (or her?) while we continued to dig and sift. We continued to volley shots in the general direction in an effort to make our nearby surroundings a less appealing for this living fossil. Undaunted, Al (as we took to calling him) stayed with us for several hours periodically surfacing near the shore for a breath of air and to keep an eye on his unruly new neighbors. Luckily, the only gator tooth I encountered was a black one that surfaced in my sifting screen. We've seen gators occasionally on the Peace but this is the only time we've been within 10' of one while in the water. We dug through a lot of the coarse gravel but it didn't deliver much other than dugong rib bones. They are exceedingly common at this site with every shovel full of material bringing up 2-3 fragments. I wondered if it was possible to dig a shovel full of gravel and not turn up at least one dugong frag and I think the only time I did was when I ventured off the gravel deposit into more sandy areas. We found a few whale (dolphin) ear bones (tympanic bullas) though most were pretty beat-up and fragmented. I had to laugh when I got 3 of these in a single screen of gravel--we ended up with 9 in total. There was a lot of small fragments of mammoth and mastodon (or gomphothere) teeth and even few small pieces of tusk ivory that ended up in our sifting screen but the largest piece of what might be proboscidean was a large rib? fragment. It's a bit big and not the right shape for dugong and besides it has a decidedly apparent marrow space. We had a nicely complete fish (shark?) vert that was just a little too big to fall through the sifting screen and so came home with us. The other vert we found was not fossilized but recent and I assumed might be gator (though I have to look through other possibilities like deer or pig as well). We were hoping for some nice glyptodont rosettes but they eluded us this time. Instead we had several armor plates from Holmesina (mostly broken pieces but one complete and in nice shape). In addition to many frags we ended up with three nice horse lower molars including the smallest one we've ever found (just over 1/2" across). I'll have to consult some books to see if this is just a juvenile Equus or a smaller species (I suspect the former). A couple of bison molar frags rounded out the mammal teeth for the trip. Turtle shell was relatively absent this time with only a few nuchal plates from the carapace and another "peace sign" gular-humeral plate from the plastron. The nearly 2" long leg spur (osteoderm) from a large land tortoise was the trip maker for me (I'm oddly quite fond of these things). Though we had dozens of meg frags (mostly nearly unidentifiable root fragments) we did find a real shamer--what would have been about a 3.5" meg split right down the center. Rather than caulk it to a hand mirror to make it "complete" this one will end up in my next goodie bag to be gifted to some unsuspecting friend's kid. The only complete meg we found was a little 2" one that oddly didn't come from the site with coarse gravel but from an area with finer gravel. After our allotted time searching for big finds at the coarse gravel site we continued down river to an area that I know has a great abundance of fine (pea-size) gravel. in the past we've found areas of this gravel bed where 3 shovels into a sifter have revealed up to 2 dozen smaller shark teeth--great fun when you have a group of friends with kids. We had a competition to see who could get the most teeth in a screen and I think the winner was something like 25 or 26. I wanted to stop at this location (coded FINE) in my handheld GPS because I figured this would be a good place to harvest some micro matrix. After seeing all of the fun that various TFF members have had picking though the fine gravel that Jeff (jcbshark) and John (Sasha) had collected I though it might be interesting to cache some of this material to play with during the off season (when the river it too high to hunt). I brought along one of my 1/4" sifters and had a piece of window screen material (roughly 1/16" openings) to set inside my new 1/2" mesh sifting screen. By double stacking the two screens I could sort out some micro matrix. The 1/4" mesh on top kept out any larger gravel while the 1/16" mesh fitted into the bottom sifter let the sand and tiny gravel pass through. This left micro matrix with a grain size roughly 1/16" to 1/4" in diameter sitting in the lower sifter. My wife took a turn with the shovel loading up the stacked screens and she hunted for any tiny teeth trapped by the upper sifter while I worked the finer gravel in the bottom screen till the sand had made it through the fine mesh. I brought along a 5 gallon bucket to dump the micro matrix into and soon had the bucket nearly filled. You can imagine that this bucket ended up rather heavy and I got the brainy idea to put the sifting screen on top of the bucket and invert it on the sandy shore so the trapped water could drain away reducing what weight I could. After it had drained well I flipped the bucket upright and scooped back into the bucket the gravel that had spilled out into the sifter. While doing this the bucket regained most of its weight and unfortunately the sandy sloped shoreline where I was working gave way as the titled bucket approached full fill tipping a good portion of its contents back into the water at the edge of the shore. After some choice words I re-scooped a combination of micro matrix, sand, and water back into the bucket and loaded it into the canoe. I'd deal with cleaning-up the matrix at home. The matrix is now spread out on a plastic tarp sunning in my driveway. Once it is quite dry I figure it will sift more easily. I'll give it another pass or to over some more window screen mesh and then store it in a dry place to play with later. I'll be bringing some samples of this mesh to Chicago next week when I head up there to do a little more fossil hunting north of the Mason-Dixon line. Though I didn't collect as much micro matrix as I had intended (next time remember to take more buckets) I may make some more care packs of Peace River micro matrix available on the Forum if there is still interest. Cheers. -Ken
  16. I'm try to break down some hard micro matrix from the ATCO formation in TX. Its a rock solid clay, almost sandstone. Now there are some very tiny micros in this stuff and i don't want to cause any abrasion to them by just throwing them in a hydrogen peroxide solution. Do you guys suggest Muratic acid? Vinegar and baking soda? Or Hydrogen Peroxide? And what are some ratios you tend to work with? And how long do you soak them? Any and all help is appreciated by this micro noob!
