A few months ago I had the opportunity to collect a bunch of matrix from the Cretaceous aged (Campanian) Ozan Formation of North Texas in the "red beds". The larger fraction is rich in sharks teeth and other small macro fauna. After breaking down the matrix, I have put it through a number of sieves to facilitate picking and sorting. I have available lots of very fine matrix that made it through my 60 mesh sieve (so it is all smaller than 250 microns or ~0.25 mm). In this fraction I see lots of forams, some ostracods, and some other very small fossils. I am not really equipped to pick and

I have yet again more Aurora fossils that I can’t identify. I would appreciate any help with identifications, these should be the last of the unknowns and I’ll create a Member Collections post about my best finds but first it would be nice to know what these are. Sorry for no scale but the diameter of the circle surrounding most photos is 10mm. 1. This one is very odd, I have no idea. 2. Fish tooth I’m guessing. Can you tell what kind. I would not want to get bitten by it. 3. This one’s larger than most of the fish teeth, about 3-4mm It’s als

I got a box of micro matrix from PaleoCris - Bone Valley Formation from Florida and I am STUNNED by the beautiful colors and preservation! I knew Bone Valley stuff was good...but wow. And he threw in some "extra" fossils of a nice big echinoid and a claw of some thing...maybe extinct armadillo. I still havn't gone through all the matrix, but wanted to show ya'll some of the nice stuff: All are around 1/8 inch - 1/4 inch This crazy Fish tooth plate - Labrodon sp. I think this is Baracuda? I love the little ray teeth Rhynchobatus. Sadly, this one

On my recent visit to search through Bone Valley material for megalodon teeth, I also was collect screened material to bring home to search in the Winter. I have been going through some and have been quite pleased. Here are a couple pics of my finds, I was wondering if the last 2 pics are a portion of a drumfish mouth plate? @MarcoSr

I recently acquired some matrix via trade from @will stevenson. This matrix is from Hallencourt France. Just the second time we gotten to go through the entire process of breaking down matrix to a searchable form. I am still in the process of breaking it down and only have searched probably less than 20%. I wanted to begin the post now as I had a few minutes to write. The material is Early Campanian in age and from the North of France. Unlike my first experience breaking matrix down which was from a location with no publication, there is a publication. Sharks from the Late Cretace

Howdy! I recently went to Post Oak creek, and ended up with more matrix than I can immediately use. Rather than let it sit unsearched, I figured it was worth a shot to post some up for trade here. Each bag has a pound of material in it, and they have proved to be very productive. I’ve found numerous ptychodus teeth, a (poorly preserved) lobster carapace, shark and fish vertebra, various bones, coprolites, and of course, lots of other shark teeth. So there’s lots of different things that can be found. I’ve got around 25-30 lbs I’d be willing to trade. I am primarily interested in verte

Hi all! I have a few things from the Aurora North Carolina Micro Matrix that I could use some help with ID. First is this odd "tooth" which I am assuming is some kind of fish tooth, but any thought on ID? Size 1/4 inch Also this little "thing". Coprolite perhaps? Size 1/8 inch and lastly this little piece: Size 1/4 inch

I purchase some matrix and it came a little different than I am use to. It was labeld "Gardner Lacality Peace River FL" and came in unprepped. This was an experience trying to break up the matrix. Not knowing exactly what I was doing, I soaked it in warm water and broke it down the best I could into different size matrix. I need something a little stronger for the other half of the clumps to break down. Everything is a unidentifiable and not complete, but I wanted to post pictures because the colors are so amazing to me. Everything is 1-3MM. As I find more items I will add to this p

Hi. I found these two teeth in the Lee Creek matrix yesterday. I have my thoughts on what they are but I wanted to see if my thoughts are correct on them. Thanks in advance for any feedback. @Al Dente 1. I believe this tooth is a Paragaleus pectoralis - 3MM 2.I thought this was Squantina but now after posting the pictures I not sure. 2MM

Hope everyones week is going well. Over the past week I found a couple teeth and something that looks like a fried egg. I just wanted to get some confirmation regarding the teeth and I have no idea what the 3rd item is. Thanks for all the help. 1. I think this is symphyseal tooth but not sure. 2-3 MM 2. Thresher shark 3MM; not sure because the root seems to fat. 3. Fried Egg looking thing; It is the same on both sides 2.5MM

Hi. Hope everyone had a great week. I found this tooth this morning as I continue to go through more of the Lee Creek Matrix. I am somewhat confident that this is a Finetooth shark - Carcharhinus Isodon. I wondering if someone can confirm if I am correct on this one. Thank you so much for any feedback.

Hi. I found this and at first I thought it was a ray tooth but I can not find any examples of it. Maybe because it is worn. This leads me to believe that maybe it is fish rather than ray. Any insight would be greatly appreciated.

I started spending a bit of time searching matrix this month. It's been a while, and I have found it to be as relaxing and rewarding as I remembered. I made a few pictures just for fun and I included a shark tooth for ID if possible. There have been a few of these odd ball shark teeth in the wonderful Cookie Cutter matrix. If anyone could tell me the position and or possible species of this tiny shark tooth, I would appreciate it.

Recently recieved a nice little package of lance creek lag formation matrix for me and a close friend to look through. I personally never handled a tough hard more dry matrix like this as I'm mostly a creek digger and my friend she is a complete amateur so this will be her first time. I'm looking for any helpful tips on how to approach such matrix. It came with two wooden sticks and some strange glue made of beads that I heard u would need acetone to break down, and if that's the case what would be the proper amount to mix? Also would it be a good idea to use the wooden stick

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.

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?

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 s

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

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.

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.

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

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.

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.

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:
