Gastropods are among the longest surviving lineages; the earliest fossils date to the Cambrian Period about 500 million years ago and their descendants continue to thrive today. This shell hasn’t just been fossilized, instead its cavities have been replaced primarily with microgranular quartz. This form of fossilization is called agatization. Measures from 26x18 to 29x13mm.
