Sorry if this is the wrong topic category, I don’t have much experience with this forum. I recently found out that there are Cambrian fossils in the Marble Mountains in California, and I’m wondering what the laws are for collecting there. I’ve always wanted to collect Cambrian fossils and that’s the closest location to me, but I don’t want to break any laws. If it is legal, what tools and equipment should I bring? Thanks!

I found this in 1989 on the upper Powder River in Wyoming. It was in an area with lots of these baculite-shaped things. I thought it would make a great knife handle so that's what I did. However, I've never seen anything like it. It has the general shape of a baculite but the exterior seems to be covered by something. I get the "sense" of a type of sea weed, or a jelly fish or something, but I doubt very seriously something soft like that could fossilize. So I am looking for an expert to tell me what I have. Also interesting, is different aspects of the "raised" features are different colors. If you can enlarge these pictures, you might be able to see the roundish darker thing. Thanks in advance for any input.

Ok, I just came across articles about soft tissue remains, apparently including some form of degraded blood, in a mosasaur. That of course, brings up the T-Rex soft tissue found, to me. I seem to understand what I keep reading, but I can’t help it, again I find myself thinking...Really? C’mon, REALLY??? Am I just misinterpreting the whole thing, or is there actually real, true, gen-u-ine unfossilized/in mineralized, preserved soft tissues and blood remains in these 70ish million year old “fully” umineralized animals? ...............HOW?????????????? How, when the rest of the animal, soft AND hard tissue has dissolved away so long ago, can any soft tissue remain? How do only small areas of the tissue remain? If conditions are so, that areas of soft tissue/blood residue remain, how do just small patches remain, but the parts immediately surrounding the patches have long since dissolved away? Conditions inside an intact bone, or intact stomach cavity, should be stable, shouldnt they? Not different from one centimeter to the next, especially so different that one spot dissolved dozens of millions of years ago, and the spot touching that one is still just sitting there, relatively preserved?

Hi all. I have seen people reference the Paasche, but complain about the capacity. What are you using? Any tips? Has anyone tried THIS unit, or see anything good/bad about it? Do you still use air abrasives if the matrix is harder than the fossil?

Hi All, I was given this fish as a present for Xmas. It is labelled as: Syngatus sp, Miocene, Nevada USA The matrix seems very soft and fragile. How would I stabilise it and give it more strength. Thanks

The other day I posted trilobite pics in this ID page thread I just used a beat up drywall saw to cut the section with the trilo out of the slab, then tried to "split" the whacked at the rest of it hoping for more. The siltstone (noncalcareous dolomite maybe?) was so soft it just crumbled. I tried tapping around the edges, which just sort of mashed in, and also tried a chisel, which just took off crumbly flakes (and I wish that was as easy when I try to nap flint). I knew if I found another specimen I'd destroy it trying to get at it, but went for it anyway as a technique-learning excercise. No joy, lots of bits and pieces but no bits and pieces of trilobites Today I collected more of what I THINK is the same material. Before I make a mess of this too, I thought to ask you experts here..... how do you hunt fossils in slabs of really soft crumbly rock? Thanks!

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.

So I was treating my collections from Betteshanger trip with Paraloid. Noticed that this specimen has this large soft yellow patch. Looks like some sort of sulphur compound? How should I treat this? Just cover the whole rock with Paraloid? Or should I remove this first?

At my main fossil site, soft fossil driftwood is pretty common, buried in cretaceous mud. It is full clam borings. Some of it looks great when first dug up, even with the bark still on it. Unfortunately, as it dries it crumbles to fragments. I think it is full of pyrite. Does anyone know how to preserve wood like this?
