What is the best place to buy fossil matrix with the most fossils?
-
I found this shell cast on Honeymoon Island, Florida, USA. As you can see from the photos it's a complete shell cast and measures about 4 x 3 1/2 inches. I did some research and found similar pictures that looked like Turritella Shell. Would the Forum agree with this ID?? If so I read that this is an extinct species of fossil sea snail. Is this correct? I appreciate your feedback. Thank you!

Yesterday I went over to Bakersfield ( Sharktooth Hill locality) East of the river. Just for kicks, I grabbed a small amount of matrix chunks to see if any small fossils could be found. Fast forward to my prep lab ( kitchen) for a cleaning. I was surprised at the abundance of tiny fossils in there and they have the same coloring as the larger teeth.lots of reds, yellows, sable browns, etc. Tonight I did some sorting and looky what I found. A very small Cow Shark tooth only 6mm long.

Hello all I recently found this at a shop with really no information on it. I am in Texas, but not sure where this fossil tooth in matrix was found; or if it is even real. The matrix looks and feels a bit weird to me. The tooth itself is about 1-1/8" long with what looks to be a long root under the matrix it is on. What do you think? Any suggestions or info would be great! KP

Psittacosaurus Partial Skeleton?
RyanDye posted a topic in Is It Real? How to Recognize Fossil Fabrications
I found this Psittacosaurus specimen online, pretty positive it is a real fossil, however not sure if this is really a Psittacosaurus for various reasons. Here are the pictures associated with it, it was pretty vague with no location to where it was found, which is why I am posting it in the is it real because of lack of information. -
Cleaning brachiopod steinkern? How to preserve matrix and clean fossils?
Kim Ellis posted a topic in Questions & Answers
Hi all, I acquired this piece, did not find on site. It seems to be basalt but the outer matrix is packed with sand and shell fragments. The brachiopods (I am assuming from the research I have done) are rather large, and appear in a cluster. Some of the fragments I have observed appear to be from the devonian era. I am assuming this is a steinkern vs true fossil. But the matrix is so fragile to clean it is destroying it. I am more of a rock hound than true fossil student. I have learned from some of my earlier posts last year that if the structure has been replaced by silica than it is not a true fossil ie steinkern, I believe. The matrix includes so much sand and shell fragments that it makes me question how silification works? Some of the shells, brachiopods, became irridescent as the stone absorbed moisture. Looks more like stone when it is dry.. . One of the pics that looks like brushing its teeth, has an opal in the background that I believe is the actual metamorphic process from this exact type of matrix and brachiopod by water and silica ooze. Interestingly as I have been cleaning the opal up also, it has the same structure as the outer pieces of the shell from the brachiopod, feather like. The striations in the opal also seem to be where the brachiopod foot would be... and also the richest mineral and most beautiful layer... Any ideas of what I should do with this piece to clean it or leave it alone I would love. If you have knowledge about brachiopods and opals I would love to hear that as well!! Thanks Kim -
Otodus tooth: glued to matrix or not?
aplomado posted a topic in Is It Real? How to Recognize Fossil Fabrications
I'm looking for a nice Otodus tooth on matrix. This one is described as "still embedded in the natural rock it was found in." It is 2.5". Does this look naturally attached or glued on to you all? Thank you. -
Hey guys! I'm curious about this egg fossil I've got here – it's been preserved with its hollow shell intact and sort of crystalized. I know there are loads of these eggs out there, but I've never seen one like this before so I'm wondering how unusual it really is. The other egg seems to be solid when held under a bright light. Here's what I know about it: – Ophidienovum sp – From a snake, I think – Tertiary/Miocene – From Mainz, Germany – Eggs are 2cm long Would love to hear your input!

Any idea what the other items besides the trilobites are in this Devonian era matrix? Especially the anchor shaped item. Sorry I forgot to put something for size reference but you can kind of get a idea from the pair of scissors in the pic.

Wondering what this fossil online is and if it's real
mattbsharks posted a topic in Is It Real? How to Recognize Fossil Fabrications
I found this online for sale and I haven't seen anything like this. Does anyone know what type of dinosaur this is or if it is even real. It makes me suspicious what with all of the posts I've seen about fakes. It measures about 9 inches. The seller does say that the rock has been repaired. -
OK, this one might be difficult as I don't have any information to go along with it. My sister bought this at a thrift store in Portland, Oregon. There is nothing to say where it is from or age. However, it does look like some of the White Water Formation fossils I have seen. The matrix is very hard stone not like compressed silt or anything that can be handled with dental tools. The tooth and bone has had a consolidant applied at some time. Can this get an ID or is that just a pipe dream?

Hi forum, I'm currently looking at a Plesiosaur tooth from Morocco. The listing says, preserved in phosphatic matrix. Does this mean it was found like this, or placed in this by the seller? Thanks

Looking to trade some partial megalodon teeth for some hard matrix
mattbsharks posted a topic in Member Fossil Trades Bulletin Board
Hi everyone, I am looking for some matrix that is the hard kind that won't break or dissolve. I am going to glue teeth to it. I have some 3/4 complete megs that I am willing to trade for it. -
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

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.

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

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'll be gathering more Bone Valley matrix
joshuajbelanger posted a topic in Member Fossil Trades Bulletin Board
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 -
Mosasaur tooth- genuine matrix attached?
aplomado posted a topic in Is It Real? How to Recognize Fossil Fabrications
Here is a 2.6" tooth... do you think the matrix is original? -
What type of tooth is this? And your thoughts on removing some of the excess rock or matrix from the crown?
