Those are really neat looking! How do you know they're marine fossils though? I'm not saying they aren't, but I'd like to know for my own curiosity. Thank you!
The first and last fossils are good examples of Stromatolites, the second one is probably a form of sponge or bryozoan and the last one is coral, maybe favosite?
Nice. Weathering has really brought the specimens out of the matrix. I used to use HCL acid... what a nightmare. Look at some geology or paleontology maps of the fossiliferous zone to get more info on the formations.
Thanks for your input! Am I correct that the first and last one are similar to a type of Sea Anemone?
No they are actually fossil representations of remnants of some of the accumulations of Cyanobacteria.
