Gastropod - Shell Structure, Anatomy, Diversity: The typical snail has a calcareous shell coiled in a spiral pattern around a central axis called the columella. Modifications and ornamentations of basic shells are widely variable among species. The gastropod body consists of the visceral hump (visceral mass), mantle, head, and foot.Ammonites are not the only shell fossils. Brachiopods are non-coiled shell fossils and can be black, white, brown or gray. Sea urchins that have been preserved as a fossil are called echinoids and gastropods are fossils of snails.

Large individuals and snail hatchlings may contain considerable amounts of old carbon, and only small shells larger than newly incubated snails (<10 mm and > 2 mg) can provide reliable 14 C ages. Our study shows that the limestone effect on the radiocarbon ages obtained from most small snail shells is negligible, thus providing a great ...

Ammonites are perhaps the most widely known fossil, possessing the typically ribbed spiral-form shell as pictured above. These creatures lived in the seas between 240 - 65 million years ago, when they became extinct along with the dinosaurs.
