Please bear with me as I am new to fossil identification. My 14 year old son recently became interested in fossils and geodes, so I am trying to encourage his interest. We found a round rock about the size of a bowling ball recently while digging to install a septic tank and he wanted to break it open to see if any crystals were inside. When he broke it open, he found some fossils, one of which I believe is called a mold fossil, images attached. The object that made the imprint appears to have had spines or thorns. Any help is appreciated! This was found in west central

Hi, I'm a rock collector/hunter and found many of these shell imprints in limestone rocks on the beach. This one looked like a bullseye or pictogram. Is this considered a fossil? Does anyone know what type of shell and/or geological time period? Thanks!
