Because ammonite shells are composed of calcium carbonate (aragonite) and nacre is a layered plate variety of argonite, their shells, especially their inner shells, have a tendency to present iridescence. William Foster, a scientist at the University of Hamburg and former postdoctoral researcher at The University of Texas at Austin Jackson School of Geosciences, led the research. Common stamps, coins, books, or toy trains are not desirable and thus demand a low price, whereas the rare or unique items fetch a premium. They are called suture lines and are an important characteristic that allow paleontologists to differentiate between the different ammonite species. Modern gastropods mostly live on a substrate (sediment or other objects) or burrow in the substrate. Archaeological digs have even found snail fossils discarded by ancient humans in paleolithic caves dating back 25,000 years. None show repair marks that would indicate severe acidification in surface waters or on the seafloor, Foster said.

The decollate snail (Rumina decollata) will capture and eat garden snails, and because of this it has sometimes been introduced as a biological pest control agent. For example if you have a fossil trilobite and it was found in the Wheeler Formation which has been dated to approximately 507 million years old, you know the fossil in it is approximately 507 million years old. Because fossils mostly represent the hard parts of organisms, snails are the most common types of gastropod fossils. Scientists use shells from sea butterflies, a type of swimming sea snail, to study ocean acidification in the present and recent past. View basket for details.
