David Gllutierrez Posted December 14, 2022 Share Posted December 14, 2022 Found this about 10’-12’ deep while digging a soil sample in Rancho Palos Verdes, CA. I’m located on the peninsula, 575 feet above sea level. Object weighs 2.5 lbs and is pretty solid. Noticed a very small shell imprint. Ignore dark colors, it was damp from cleaning. any ideas on what it might be? Link to comment Share on other sites More sharing options...
Ludwigia Posted December 14, 2022 Share Posted December 14, 2022 It's a sandstone concretion and you're right about the bivalve imprint on it. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
