is this a fossil?

Found in San Pedro creek connecting to San Antonio river .Texas







If it's a fossil, any idea what it is and how old?

Thanks!!

Also anyone know what kind of bone this is?

Your first item looks like a section of a shell or oyster, and as for age, well, that's a difficult one. Your piece of bone is most likely either a rib bone from pork or beef.

Thanks for the input. Do you think it's a fossil?

Calcium carbonate is what it would be made of. Oyster was my initial thought as well. A close up of the second item would help. I agree it does look like pig bone. Is it bone or has it permineralized?
