Is this a fossil +what type of rocks are these?

Hi,

 

If you want identification, measurements, a more accurate location than the state and closer photos could help.

 

I can’t say anything specific with what you’re presenting, other than it seems more geological than paleontological.

It was in college park, and here are more pictures. Unfortunately that’s all I can give. From what it looks like I think it’s an ironstone concretions, but another person said it could be a blastoid

I'd stay with your original thought.

Consider a possible cast of trace fossils -- fodichnia or domichnia.

I doubt it. The texture seems too layered, as if an iron rich pocket/layer served to feed a concretionary front.

Can you explain what this means in some simple terms for a high school student? Hehe

Original thought that it’s a fossil or concretions?

Concretion.

Concretion as a process occurs after sediment has been deposited. Soluble or mobile minerals typically are transported by ground water and deposited often in layers which are roughly concentric to the mineral source. It might not be the best explanation, but that's my thought.

He believes the layered texture points to it being a concretion.
