  1. Hi everyone! A couple of weeks ago I aqcuired some microfossil samples, one of which was a sample from the Lede Zand, Lede Formation, Oosterzele, Belgium (Eocene, Lutetian, 44 mya). The sample is very rich in Foraminifera & shell fragments, but I also managed to find a tiny shark tooth. While I already searched at belgiansharkteeth.be I can't seem to find a match, perhaps due to it being so small. So I was wondering if anyone here might be able to help me out, I would be very gratefull. Thank you in advance!
  2. Is this anything?

    I’ve just recently sifted through some permian micro matrix from Oklahoma and I came across this and wasn’t sure if it was anything at all, it was very uniform and sleek so I didn’t immediately assume it was a pebble, it also had that strange split on one end. I’m not even sure if it’s a fossil.
  3. Hi again from West KY. Hope these photos are OK. I've wrestled with them for a couple hours now. (LOL) This was found with some others while I was walking a creek in the Jackson Purchase area of KY, Graves County to be exact. This was on the surface, as were the others, all near each other. They look to have been washed out, as the banks of the creek are, in some places, as high as 15 - 20 ft. The other side was cut out in the 1800's to make a railroad track. The ruler didn't come out clearly, but, this measures about 9mm x 7mm x 5mm, weighs 552g. This area is known to have been under water, but most of the fossils I find are the small ones. When I saw this, I wondered if it was possible to have had a creature this large swimming HERE? That led to learning about the Western Interior Seaway, and yes, it DID reach here, (very exciting!). After researching this and another bone found with it, I came to think that it was a possible cetacean with signs of Osedax, during the Cretaceous perhaps. (?) After reading about Osedax, I found that now, the various species usually are separate from each other, but that in the W.I.S., many species would feed off of the same bones. *I added a photo of one of the others found with it. Just the one. I've second-guessed myself 1000 times about this and the other "bones", looked for other things that seemed more plausible, and been through tons of photos, websites, & scientific papers. The University of KY website didn't help to squash my excitement - here's a quote from them: "Cretaceous sediments are almost completely absent in Kentucky; only small areas of Cretaceous deposits occur in and near the Jackson Purchase Region in extreme western Kentucky. During most of the Cretaceous, Kentucky was land. If Cretaceous sediments covered any of this land, they have since been eroded away. However, during latest Cretaceous times, sea level rise coupled with subsidence in the Jackson Purchase Region led to deposition of coastal sediments in environments that included coastal plain, river, delta, and shallow sea. Because of the limited outcrops in the flat Jackson Purchase Region, very little in the way of fossils have been found in the Cretaceous sediments there. The most common fossils are coalified tree limbs. The potential exists for dinosaur fossils to be found in these sediments in Kentucky. Much more new research needs to be done on the Cretaceous in this region." I know some of you all can help, and it's very much appreciated! Even if it IS nothing more than a coral or whatever, at least I will know!
  4. I recently created this set of micropaleontology themed drink coasters. When stacked, the coaster set resembles a geological core sample, containing fossils ranging from the present day to 1500 Ma. For anyone with access to a 3d printer, the cad files can be freely downloaded here: https://sketchfab.com/taylorcustom/collections If anyone has requests for other such projects, I welcome suggestions!
  5. I am in the process of creating a micropaleontology themed artwork., and even after having received a good amount of expert help, I feel overwhelmed by the subject and would like to get more opinions on my composition. The piece will consist of a series of disc-shaped layers, each of which will bear microfossils from a different geologic time period. These layers will be stacked like a roll of coins, so as to look like a drill core. The attached image shows a part of my research spreadsheet, including images and descriptions of each layer. If anyone here has any thoughts on the organisms I have chosen, or how I have portrayed them, I would love to hear! Am I missing any perennial favorites? Is my selection skewed too much in one direction or another? Thanks for taking the time to look, and thanks in advance for your comments!
  6. Looking for a Stereo Microscope in Europe

    Hi everyone! I'm looking to buy a Stereo Microscope in Europe for microfossil observation and was wondering if anyone can point out recommended brands. The price range for me is <400 Euros. Thanks!

  8. I would like to share some pictures with you from my first hunt on microfossils. Hope, that you will help me to identify some of the fossils. Description: Gray clay with foraminifers. Bed of the river Losis, 100m from river Venta. J2 Callovian Sample taken in year 2005 Processing of the sample: First, I cut a small amount of clay from the sample (~35-50 gr.). This piece was then desintegrated with hydrogen peroxide(3%). Then I washed this sample, using 2 sieves (100 microns and 63 microns) for about half an hour. Both fractures (>100 and >63 microns) were separated between two envelopes for drying. Then sample dried for 2 days within the room temperature. Looking for fossils: I don't know, what I did incorrect, but after drying, sample solidified a bit, and I needed to grind it a bit with my hands. It seems, that not all clay went away from the sample. The color of remains still was dark grey. I am using a simple 20x-40x scope, and I saw, that sample is full of something, that reminded me fish scale. A lot of small, blinking pieces. For now, I have searched through only >100 micron fracture. A lot of interesting stuff was found there. I need to apologise for the quality of the pictures. I don't have a special scope camera, so I took some pictures with my phone through the scope. Some pics(pictures are large, so I include only links to them): 1) http://i.imgur.com/5rfKmss.jpg Here I separated those shells in two groups, because the group on the left is more yellowish. I think, this can be another species. I was trying to identify this using foraminifera.eu and it seems for me, that these can be some Lenticulina ? 2) http://i.imgur.com/u4ljqJv.jpg Could not find any one similar. Looks like what I see on the top of the shell are chambers without a top layer? Or this is some kind of special ornament? 3) http://i.imgur.com/MQw5BOb.jpg These looks like Discorbida ? 4) http://i.imgur.com/pOP6QWy.jpg Have not found any similar in "Key to species". 5) http://i.imgur.com/TzPH3OJ.jpg Also no idea. 6) http://i.imgur.com/7niz8hW.jpg Same story Some other photos of microfossils, that are only in 1 sample : http://i.imgur.com/LgTMDPR.jpg http://i.imgur.com/IRHw12P.jpg Thank you for your time reading this post. I hope to see some answers. If you have any tips or you see something, what I did wrong, please, advise me! I am just starting, but I really like micropalentology and I want to study!
  9. Dear FFers: For the last few weeks, I've been researching suppliers of micropaleo slide sets. I haven't had to buy them since 2003 (!!), and I'm a little shocked to find how much the prices have soared. In any case, the most economical place I've found in the states (at least so far) is Lakeside (http://www.lakeside-products.com/html/paleontologic.html), which sells in lots of 100. I certainly don't need 100, so I was wondering if anyone would like to split an order with me. What I need are the 18-60s shown on the link (2mm thick with a ruled, numbered rectangular field). I could go for the 3mm-thick ones, if that makes a difference to anyone. It would come to about $60 (which would include shipping w/in the US) for 50 cardboard slides & 50 aluminum holders. You're on your own for the glass slides, but there are lots of options on eBay for as low as around $9/gross. All best, Wendell
  10. As I've been learning about my new to me Bausch and Lomb Stereozoom 4 microscope I discovered that the indention for the stage plate was 120 mm. 120 mm is the size of a standard CD or DVD. (Totally irrelevant aside about the nature of memory, or at least my memory. Somehow I knew the dimensions of a CD. I can't remember someone's name two minutes after I shake their hand, or a phone number 10 seconds after I leave the phone book. Sake should be served at body temperature--98.6 degrees Fahrenheit. I learned that almost useless fact at the age of ten from an Ian Fleming novel about James Bond. It's still with me 40 years later. Regardless, a CD fits perfectly into the stage of my scope.) The tinker in me started thinking about custom stage plates for photo backgrounds. I'm not an engineer or scientist. I'm a sixth grade science teacher, an amateur naturalist, and a jack of all trades, master of none. But I saw an opportunity for invention. Unneeded CDs are not nearly as ubiquitous as they were during AOl's heyday, but I would imagine most folks have more than a few around. The above just have circles of various colored construction paper glued to both sides. Various old maps and cross sections. One of the plates in my scope base. Good for macro photos. Good for micro-photography as well. Now that I've discovered this neat hack, I want to make some more plates that are even more customized. Current or historic USGS topos for the actual sites where the fossils were collected. Maybe Google satellite images as well. Cross-section from the collection site. I also want one CD with black/white one either side, and a scale, for field photography. And one with a grid for sorting and fauna analysis/species distribution.
  11. Hi everyone, I would like to shear my blog on micropalaeontology with you, and I hope you find it helpful. It is my honour to receive and shear your opinion in micropaleontology. The blog needs time to be completed, and I am ready to know your suggestions about it. Link: Micropalaeontology Blog Regards, Majed
