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

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:

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

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.

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 t

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 wh

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 wa

Suggestions For Breaking Down Some Matrix Please!?
fossilized6s posted a topic in Micro-paleontology
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!
