Help me id mold fossil please
Jewell1212 posted a topic in Fossil IDPlease 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
Mold Fossil of Shells?
