  1. 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.
  2. Hollow Reptile Egg Fossil

    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!
  3. 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 I have learned from some of my earlier posts last year that if the structure has been replaced by silica than it is not a true fossil ie steinkern, I believe.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
  4. 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.
  5. What is in this Devonian matrix?

    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.
  6. 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.
  7. Matrix Question

    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
  8. To whom do I belong?

    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?
  9. 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.
  10. Saw for cutting rocks?

    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
  11. Another "seashell: fossil or not" topic

    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
  12. 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
  13. Succesful Fossil Hunt

    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
  14. 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.
  15. Any ideas what is in this matrix?

    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.
  16. 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.
  17. 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
  18. Here is a 2.6" tooth... do you think the matrix is original?
  19. Coprolite

    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
  20. Brazos River, Texas - Tooth

    What type of tooth is this? And your thoughts on removing some of the excess rock or matrix from the crown?
  21. WHAT ARE THOSE!?

  22. Hi, i'm doing some practice of fossils prep, like i wrote in the title im looking for some unprepared fossils , better if from uk or europe. if someone got some let me know. thanks!
  23. 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
  24. 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
  25. 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.
