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

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.

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

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 wit

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.

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/

Eocene aged Meridian Mississippi micro fossils (mostly shark teeth)
britishcanuk posted a topic in Fossil ID
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 -
hey guys, found this interesting little tooth while sorting some STH matrix. Any clue who it belongs to? Or what tooth it is?

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.

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.

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

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!!

Gainesville rattlesnake creek micro matrix
Sir.tommy.the.toad posted a topic in Member Fossil Trades Bulletin Board
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 -
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:

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.

This specimen was found in Sacha's Peace River matrix. Any ideas?
-
I had saved a cup or so of the dregs off the bottom of a gallon bag of Peace River matrix a while ago. I wanted to see if the really tiny stuff had any more of the 'cats paw' denticles like the one I found here. ; Peace River Find For I D Please - Fossil ID - The Fossil Forum I went thru it today, and found another! This one is better preserved on the dorsal side, but doesn't have the detail on the base like the first. It is really worth checking the tiny, sandy stuff at the bottom of a batch of matrix.

I found this tiny, micro sized regular echinoid in some matrix I collected at a site near my home. 2.92 millimeter across. It is from the comfort Member of the Castle Hayne Formation, Late Eocene here in eastern North Carolina. I have been attempting to ID it, but have really come up empty. It does not help that it is coated in a calcite? matrix. I have looked at it under a loupe and my digital scope. I have taken pics with a camera on the macro setting and with my scope. Very very hard to focus in sharply on it. Anyways, according to Porter Kier's "The Echinoids of the Middle Eocene Warley

Here is another tooth from Sacha's Gainesville matrix. It's only the crown, but I'm hoping someone will recognize it's previous owner. I'm guessing a carnivore... Thanks for looking. Julianna

I found this little mammal tooth in Sacha's matrix from Rattlesnake Creek.The top most images are of the root base and the occlusal view. Can anyone tell me which critter it belonged to? Thanks, Julianna

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.

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

So I have been playing around with taking pictures through my microscopes over the last year or so and so far I have not bee terribly impressed by the quality of the images. I purchased a Celestron 2MP digital imager (http://www.amazon.com/Celestron-Digital-Microscope-Imager-44421/dp/B003DVP7CE/ref=sr_1_1?ie=UTF8&qid=1385480943&sr=8-1&keywords=digital+imager) which was quite cheap ($35) last year and the picture quality is pretty poor, which is about what I expect for 2MP. I have a DSLR camera and a mount that I have used, but I have an older DSLR without live view which makes fo

I recently received some Blue Hill Shale matrix from a fellow forum member to break down and search for micro and mini teeth. After the second break down cycle I found this tooth that I am trying to get a positive ID for. It has been suggested Psuedocorax or possibly a symphyseal by another forum member. Any thoughts?
