Gemmula
Gemmula, common name the gem turrids, is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids.
These snails have been recorded as fossils from the Paleocene to the Quaternary (from 66.043 to 0.012 Ma). Fossils have been found all over the world.
They are venomous with disulfide-rich polypeptides in their venom ducts. These bioactive peptides are likely to become a resource for novel pharmacologically active compounds
