Does anyone know of any good resources on and/or off the forum to learn proper techniques regarding sudden field excavation? More specifically, in the event of a significant/highly fragile find, how to properly consolidate, collect, and transport it from the field, especially in limited circumstances where proper tools, glue, paper towel/tinfoil may not be available? I’ve got the documentation/field notes bit down, but I wanted guidance on the extraction part. Photos, articles, videos, books, etc. appreciated! (Note: if this is too specific or narrow of a search request, that’s ok, any even mildly relevant material is appreciated regardless)

Hi everyone, would Butvar B-76 be good to help seal and stabalize a leaf fossil in shale? Would I just put it on the surface or submerge the whole piece in the solution? I'd like to keep the fossil looking as natural as possible, not glossy at all. Thanks!

I've read all kinds of articles and posts about MIXING Paraloid, but having never used it, I don't know how much TOTAL VOLUME to mix. I'm planning on preparing some brachiopods (some are broken) and a couple of medium (9-10") ammonites, which are fragile. I'll start with a 5% solution, since it seems best to start with a minimal amount, and work up if needed.

I've got a small horse tooth from the Peace River near Wachula. It's got a big split down the middle and seems to be only getting worse. I submerged it in an unknown higher concentrate of paraloid-b72. Do you guys reckon that will be enough to halt the split? It was a deep split nearly separating it in half. I submerged the tooth for a few minutes in solution to completely saturate the tooth.

Hi all, Ive got a hadrosaur bone section that is quite fragile and breaks off a bit. Luckily, it has not broken into tiny pieces yet but can be fixed with some glue. Though I would like to avoid further breakdown to it and was wondering if there is anything I can use as consolidation that you guys recommend? Ive searched the forums and from what i can tell, paraloid b72 seems to best, though Im not sure where to get it in person as most are I think online only. Ive also seen that PVA is also good however Elmer's glue isnt recommended as it becomes sticky over time with humidity. Are there maybe other alternatives to these that I can purchase from in store? Im from Syd, Australia and hopefully there are maybe others that know possible local shops that may carry fossil-specific stuff haha. many thanks!

Hello, I heard you can use "all purpose glue" that's apparently used in schools, mixed with acetone to make a cheap consolidant. I need a lot of the stuff for a pretty "far gone" fossil. I think I managed to find something, but I am still unsure whether or not I could use it (if it's the right type of glue). (What I need) (What I found)

I have a few pleistocene bones and large shell fragments that are fractured, and I'm unclear on the best way to repair them. I've read many topics on the forum about the importance of consolidation and materials to use, and I have materials on order, so I should be able to get started soon. But I'm a little unclear on the process if the bone is in two or three pieces. If you have a completely broken bone, should you consolidate the broken pieces separately first (i.e. in an acetone/butvar mix), then glue them back together with something like CA glue? Or would the consolidant make it harder to piece and glue them back together after they dry? Thank you, Brandy

Hi there, I picked up a couple of pieces of flaky shale with some bivalves and ammonites from Whitby a couple of days ago and want to use a paraloid-B72 solution to consolidate them. I’ve never done this before so am hoping someone can share some advice. At the moment I’ve got them soaking in water to remove any salt and in a day or two I’ll remove them to dry naturally. I want to do a bit of prep with some dental tools and then consolidate. My main question is do you think I should soak them in the paraloid or brush it on? In terms of dilution I want to buy a premixed bottle as I live in a small flat and want to avoid stinking of acetone as much as possible. The lowest concentration I can find is 5% wt/vol, would this be suitable for submersion/brushing on? If submerging, how deeply does the specimen need to preserved and can I submerge more than one specimen in one container? I can see myself having to buy a lot of solution for this... Sorry for all the questions, I’ve found it quite difficult to find clear answers online. Here are the pieces in question

Hey, I recently purchased this nice eldredgeops trilobite with some pyrite inclusions. I have some other nice pyrite fossils from the Silica Shale, but this trilobite's eye pyrite look like it could flake off in time if not treated. I live in Missouri, which is a humid state as well. Would anyone here know or recommend using mineral oil, paraloid, or some other material to consolidate/ protect the pyrite on the trilobite? Also would it be advisable to coat the entire bug, or just the pyrite spots? Sorry for the rough pic, the bug is still in the mail. Thanks, jackson

Hello, I'm a newbie. I'm looking for advice on what product to place on the fossils in the boulder below. I want to stabilize them in the matrix before I do any more removal. The photo with the (5) had a great rib in it but crumbled upon getting the rock into my truck. Fossils are exposed on many sides. As I began removing matrix with my Dremel 290, more fossils were uncovered. I read many articles and posts about solution adhesives. I want to keep it simple. I found premade Paraloid B-72 Glue, and the more complicated acetone and b-72, b-76 pellets. I may try and use a filler on my rib (1) that has a crack. This has been a great COVID hobby for me. My science students will get fossil remnants from me as student of the week rewards. Suggestions welcomed.

Hi All, I am very new to prepping, so thank you in advance. On the base of some of the small teeth that I have, I like to place superglue to prevent "crumbling" of loose particles. The superglue works great but leaves a shiny/glossy appearance. Is there something better to use? I have Vinac beads that were given to me but not sure how to use it in that capacity. I placed superglue on the left tooth and nothing yet on the right. Thanks again

Hello everybody! I have a fossil in a matrix and I want to keep and not to clean free. Does anybody know what to spray on a limestone matrix to consolidate it? Thanks!

Ok I have a large mostly complete bison skull I need to consolidate as it has started flaking. I have some butvar 76 and acetone, which I understand I should mix at a ratio of 1:50 for stabilizing. I have soaked old gun stocks I mb acetone in aluminum pans in the past, I am thinking of doing this as it appears for stabilization you want to submerge the skull for about 10 minutes, not just pour it or paint it on correct?

Found a paper today using Paraloid B-72. It’s a very useful read for any that prep

In tandem with the phytosaur prep, I’ve also started a very challenging bison skull project. This specimen is sub-fossil bone and VERY soft. The bone inside the foils wrapping is a crumbling mess. First step was to wrap it in towels and let it dry for a week.

I just received what I thought was pure acetone for mixing with Paraloid B72. However there is an additive of denatonium benzoate, which I assume is a required bittering agent to prevent consumption. Will this cause any issues?

I am going to feel bad if there is already a post with as much information as I am looking for, but I can't seem to find one. Essentially, I am having a hard time finding the proper consolidation materials. I have never prepped before, and I am going to be starting my first project this weekend. That being said, the extent of my knowledge of sealants comes from research on this forum. I am looking for the right materials to use (with or without acetone dilute) to keep my fossils from being damaged while working on some Moroccan matrix. I'm not finding anywhere reliable to purchase PVA B-15, Butvar, or anything of the sort. Is there a more easily accessible material I can work with? I need very little at this point in time, and not necessarily something expensive or overly high-quality as the items I will be working with are small and cheap. What are other alternatives that people use, and what are the benefits of each of them? I am eager to know all there is to know, and I've been slowly going down the list of each of the topics in this thread hoping to find what I'm looking for!

I recently acquired this nice algae specimen from one of the many Chinese Cambrian lagerstatten (Hongjingshao fm). The algae is preserved as a film on the shale, and unfortunately the shale is quite flaky. Several pieces of the lighter gray matrix have flaked off already, and there are quite a few other areas that look like they could fall off with the slightest bump. I can go ahead and glue the pieces that have fallen off back on, but I'd like to prevent the rest from coming off. However, I'm worried that the algae would quickly wash away if liquid touched it, especially something as harsh as acetone (if consolidated using standard methods). This is certainly the case with many fossils from similar formations. Do I have any options here?
