really cool fossil turns out to be really cool fake, but it had long puzzled scientists so it did not completely fool everybody, and may not even be an intentional attempt to deceive link for details

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?

I found this today in a stream bed. It doesn’t look like just a rock to me. Seems to resemble bone with tissue. Any help in identification would be greatly appreciated
