No idea what these are, marine Miocene

Here are two fossils I found today , they are from Southern California marine Miocene rocks. The one with the spike looking thing is around an inch (you can see my leg for scale reference). Absolutely no idea what the first is, the second looks like some sort of plant or arthropod.

 

Thanks in advance

I am not seeing anything that is identifiable as a fossil in these pictures. It looks like mineral stain and fracture marks.

Even the second one ? Could have sworn it looks like some sort of plant

The top image could show plant material. I'm not 100% sure that this isn't bone from this image. The orange but to the right looks like a fish scale.

I would prep these more with a needle.

Looks like soft mudstone?

 

The bottom image may also be plant material. First I though bone but we would need it cleaned up a bit and a clearer close up. It is most likely carbonised plant material with some sort of mineral coating (calcite?).

I would suggest prepping and clean these, especially the first one. It looks like it has a nice defined fossil plane that should be easy to prep away. I see fossils in both.

I agree there is something in the first picture. Prepping is a must to determine what it may be. The second piece, I am not so sure.
