Hi! I was searching my backyard for fossils (even though I knew I probably wouldn't find anything), when I came across a piece of shale that was splitting. I used my pick to split it, and I found these "fossils". I'm not sure if this is even a fossil, but it looks like some kind of carbon film. They were so small that I couldn't take any good pictures of them. Each of these "fossils" are ~2 cm long. The rocks I found these in were there when I moved into the house, so I don't know if they were already there, or if they were imported.
The first one resembles the possible anomalocaridid relative Pambdelurion, or at least that's what it resembles the most. The second "fossil" is what looks to be some kind of Arthropod with overlapping swimming fins. The last one looks to be some kind of frond (possibly algae?). Any help would be much appreciated, even though I doubt they are even fossils.
