Hi all, I know what you're thinking: "Oh god, not another fossil or not seashell topic by Max! " But I need your help again. I'm pretty sure that this one is a fossil, as it is stuck in solid matrix. I'm not completely sure though. Definitely some kind of oyster/pycnodont, this one was found at the beach of Vivari (near Nafplio, Greece), at about 2m of depth (yes I dived; there were many pretty modern seashells in the area, and I eventually stumbled on this one). If there isn't enough detail visible to say, I can try to prep it a bit. The matrix is very hard though, so I can't guarantee success on the prep. What do you think of this one? Best regards, Max

Hi everyone! I was playing around with some matrix fragments from the phosphate deposits of Morocco and decided to give it a dip in water to see what would happen. What surprised me is how quickly the pieces crumbled into tiny clumps. Practically 80% of the matrix was gone in less than 10 seconds, dissolved by the water. I could very well have picked up a piece from dried mud and it would give similar results. I always thought the Moroccan stuff was a kind of sandstone, but what I saw suggests it is more of a clay-type rock? Then again, can the matrix even be considered a rock given how "fragile" it is? Would love to hear your thoughts! Jay

Hello all! Recently, I went down to Beaumaris to look for fossils. We were there for a few hours and only found the usual fossils (Lovenia Woodsi) But as we were making our way out of the site, I spotted a large and unusual rock laying in the sand. When I picked it up, I was surprised to find it was filled with a number of fossils and fossilised imprints of shells and over invertebrates. Does anyone know a good way to clean the fossil or should I just leave it? Thanks, Dan

I was scrolling through eBay when I saw this specimen but I don't know whether it's real because I might consider getting it. It is a Discosauriscus.

Noob here. We tried our luck near Andalusia, but as expected the water was too high. We ended up in Sepulga River and this was all we walked away with, but still curious what might be here. There were lots of new mollusks strewn about and I grabbed these just as a MASSIVE huntsman spider chased me off.

Dear fossil preparation experts, I recently acquired a series of articulated vertebrae of a Mosasaur in it's original matrix. The fossil is coming from Kem Kem region in Morocco. My goal is not to extract the fossil bone from the matrix. This would be quite difficult due to the fragility of the specimen. Instead, I would like to clean up the matrix to make it look nicer. Now, my problem is the following: In some areas the matrix is quite dense and hard. In some other areas it is extremely brittle (almost like sand). I would like to use this original matrix-sand to repair the matrix in some spots. I was thinking about mixing the sand with liquid (water? glue?) to get a material that I can use for re-modelling the damaged matrix. Does someone have a good recipe for that? Thank you.

Hi all, do you know if there is a type of hand saw that can be used for squaring off rocks? I know some are probably too hard, but thinking of Green River plates or maybe Utah trilobite shale. Thanks! Nathan

I'm heading out in the morning to gather more BV matrix, as it was so popular the first time. Same rules apply, send me whatever fossilly goodness you feel like, and I'll send you a ton of this stuff. I'll try to be selective on the pieces I gather tomorrow, but as always, it's always a gamble. I'm interested in all fossils, verts, inverts, and plants! -Thanks J

Here is a 2.6" tooth... do you think the matrix is original?

Can someone tell me the best way to disassemble (?) coprolite in an effort to locate any hidden items? About the only thing I have come up with is a big hammer and I fear destroying anything of interest. Regards, Michael

What type of tooth is this? And your thoughts on removing some of the excess rock or matrix from the crown?

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

I got this Titanother tooth the other day and I wanted to clean some of the matrix off. I was wondering if anybody had any tips or tricks on how to do this. What kind of tools should I use. Should I soak it in water first? Should I just leave the matrix on there? Any advice and tips would be appreciated. Thanks Tom

Any chance there's a shell hanging on to this ammonite? I'm talking about the protrusion on the bottom right, at 5 o'clock.

I used to just bag up loose matrix from bone material to sieve for macros. This is the first time I've tried drying out the dirty water from gently cleaning the bone. I'll post some results in the New Year if I should fine anything interesting.

Beautiful Matrix I found along the James River one day! My favorite still! Perfect condition.. Still need help identifying the exact type of shark, or Era...?! -
What do you guys use for cutting down matrices that are err rock hard? I've thought of a tile saw but unless a lot of money is spent then the depth of the cut is really small, 25mm/1in. Would an angle grinder with a concrete blade work? Thanks John

Due to the delicacy of the ammonites found in the slate I like to keep them in-bedded in their natural matrix.© Lolman1c

I have dug up a number of middle Pleistocene bivalves and gastropods but some have a very friable (crumbly) matrix. Is there some spray or something to seal and preserve it?

I have dug a number of bivalves and gastropods out of a very friable, crumbly matrix. Anyone have any experience how I can preserve some of the matrix and also make the specimens look good?

These were collected when I was probably ten years old (I am now 21), so I do not know the specifics of where these were found. I only know that I was somewhere around the Kansas/Nebraska border (SE part). I was hoping to get some input as to what fossils may be in these slabs? I know there are brachiopods, crinoids, an fragments of corals. I was hoping to maybe get some specifics, or general ID's on some of the fossils. There are some that look like fish ribs or spines of some sort. Any input is appreciated!

This tooth in matrix has been sitting on a local diver's desk for about three years, under a dust cover, and has remained very stable. We think the matrix is essentially a phosphatic nodule. It's basically a piece of the ACE River Basin river bottom, and obviously it's an amazing specimen. I wanted to prep. it using a hardener, but I've never prepped any fossils before, and wasn't sure which product that I should use. I've heard of Butvar, of course and know people use it on bone, but this isn't bone, it's more mineral. Should I dip, or brush? It would seem a lot cheaper to brush it on. I'd also like something that would be water proof, afterwards. Any thoughts or ideas would be greatly appreciated. I'd also like some direction on a reputable seller of the product. Any folks here in that biz? If you are, then I'd rather throw the biz to a member, but I will need the product over nighted to me. I want to do the job myself, and I won't be doing a lot of prep. work, so I don't need a ton of the stuff, just enough for this one piece, which measure's about 10" in length. Here's a list of products that are advertised on a site called PaleoPortal Fossil Preparation. - http://preparation.paleo.amnh.org/47/adhesives-and-consolidants Solution adhesives which set by evaporation of a solvent and include:Paraloid B-72 (ethyl methacrylate co-polymer, formerly called Acryloid) Butvar B-76 (polyvinyl butyral, or PVB) Butvar B-98 (polyvinyl butyral or PVB) McGean B-15 (polyvinyl acetate or PVAC, formerly called Vinac B-15) “White glue” dispersions and emulsions (e.g. Elmers, Rhoplex, Lascaux) - Not Waterproof, so not my choice Thanks in Advance, guys ...

Given the enormous number of repaired Megalodon teeth, which we must endure, and in honor of the new sub-forum here, I thought this might be a good time and place to revisit a classic case. It all began with a simple, but hopeful question, put to the membership here, last year. The item below was the item in question.
