Mountain Mineral Market on Instagram: "Trona frogs are fossils of the modern era found in the Owens Lake region of California. These frogs were exceptionally preserved due to being replaced by the mineral trona (a type of salt) after being swept into the lake during a major flood. Their discovery in 2023 makes them a particularly new and highly sought after find. • #newfind #tronafrogs #fossils #fossilsofthemodernera #availablenow"
