So yesterday, I found several associated verts to a large fish. It was partially exposed on the creek bottom and it had been awhile since the last rain, so tons of algae grew on it. I managed to pop it out in one piece and have begun trying to clean it up. Since fish and shale are sensitive when it comes to drying and wetting, I've kept it in water for the time being while I attempt to remove the algae. I will paraloid sections later once the algae is gone. I tried submerging the specimen overnight in about 2:5 bleach water solution to kill anything living on it. Afterwards I was a

So, what is the safest way to remove matrix (sandstone and limestone) from calcium shelled fossils. Everything I've read involved acids (some pretty dangerous). What is most ecologically friendly and safest way? I have picks and dramel , but these shells are very thin and almost impossible to remove from the matrix. I am thinking that weaker acids might not work that well and the costs of using more powerful stuff would require a special room with exhaust systems and ways to neutralize the stronger acids to make them environmentally safe. Images are typical of fossils I want to extract.

I have a few specimens that I recently collected from a river. The best are covered in dried algae that needs removal. Does anyone know how to remove the algae?

I am wanting to remove this shark tooth for photography purposes, but it is attached to the display case via some putty-like adhesive. I haven't tried poking at it in fear of damaging the tooth (which is quite brittle), but it does appear to be somewhat hardened, although I may be wrong. Does anyone know how to best remove putties using household materials with minimal damage to the fossil? Any help is appreciated.

Hey there, im hoping some of the clever folks here might be able to offer some advice on a prep im working on. Im currently prepping a large 150 - 200 pound block. In the initial prep, a part of the block cracked and opened up a small crevice. This crevice did not beak completely into two pieces, it was still held together by the un removed matrix surrounding the fossil. At the time, i didn't want this to slowly shake into a bigger crack or lose pieces due to the vibration of the air tools. There was/is a lot more prep to do and between prep and flipping over a large block i was worried about

I have several good Eldredgeops rana specimens from Penn Dixie Fossil Park, and they were fairly clean when I hacked them out. Unfortunately, there is a lot of shale stubbornly stuck in the groves and crevasses of the trilobites. I have access to a dental sandblaster, but I'm not sure if it's safe to use. Any thoughts?

I am trying to prepare this nice plant fossil I found in Wyoming, but can’t figure out how to remove the glue marks left over from stabilizing the fossilized piece of branch in the center. The glue marks are the dark area near the fossilized branch. Anyone have any advice?

This tooth can be cleaned off more than this, cant it? It looks like there's plenty that is layered on top of the actual tooth that should be able to be removed, but I know it's not always as easy as that. And of course, not just if it CAN be removed, but removed safely? More to the point-safely by an amature?

A few weeks ago I picked up a few Edmontosaurus ribs and two fibia. Was working on getting a bunch of trilobites prepped, but finally getting around to starting on them. They all look like they have been covered in elmer's glue, guessing as a field consolident. I have some acetone I was thinking of using to remove the glue, and then I had planned on using some Paraloid B-72 to reconsolidate the bones. I am concerned about whether the bones will all fall apart if I do an acetone soak, especially if some of the smaller pieces will soak up the liquid and disintegrate. Not sure the safest way to d

Ok so while in morocco I bought 2 rib fossils but have been poorly put together in my opinion trying to remove said mystery glue I heard acetone works and did soften and turn to a loosish sticky gunk however now it has dried the bones have this white milky coating over them is this normal? I've never had to remove glue before any help would be appreciated. Matt

This is a long-shot, but I'm going to try it anyway. I've found two very large logs of pet wood that I would like to attempt to extract from a creek bed. The soil is very sandy, at an approximate 50-degree angle covered with vines and saplings. We can clear those; that's not an issue. There are a few small trees. We have several tow straps and a come-along and are considering purchasing a cargo net. The problem comes in where if we finally make it up the bank, how do we get it to the truck, into the truck, and back out of the truck. These specimens are probably at leas

ok, so I bought this spinosaurus tooth, but now I want to remove the sand & dirt. I do not have expensive tools such as airblasters etc, but i do have tweezers, tooth cleaning bristles (with a wire inside), a small paintbrush, and if you can suggest any other household items that would be great. I would like to know how to remove the sand and dirt without endangering the tooth too much. thanks.
