Fossil snail.

Some gastropod shells have a tall (high) spire composed of many whorls, while others, lack a prominent spire, and consist of only a large body whorl. Most modern and fossil snail shells are dextrally coiled (right coiled), which means the aperture is on the right side of the axis of the shell when looking at the aperture.Sediments in the Zanda Basin contain abundant gastropod, fish, and mammalian fossils, and the chronology of the sedimentary sequence has been established through magnetostratigraphic and biostratigraphic studies (Saylor et al., 2009; Wang et al., 2013a).

The remains inside the rock also turn to rock. The remains are replaced by minerals. The remains literally turn to stone. This type of fossilization is called permineralization.
