Lot: 2 to 2.7" Polished Fossil Gastropods - 43 Pieces

This is a polished internal mold of a fossil gastropod (sea snail), likely of the genus Calliotropis, collected from Madagascar.

The fossilization process allowed for calcite crystals to form within the gastropods spiral, some of which are visible by looking at the underside of the specimen.

Gastropods, or snails, have been around since the Late Cambrian period. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. There are 611 known families of gastropods, of which 202 families are extinct and appear only in the fossil record.
