Turitella Agate Cabochons
Turritella Agate is from a silicated sedimentary layer that contains fossil shells of gastropods. The snails
are actually properly refereed to as Elimia tenera, in the family Pleuroceridae. The rock in which they are so abundant
varies from a soft sandstone to a dense chalcedony. It is this dense silicified rock that is so popular with gem and mineral
hobbyists and Turritella Agate is a very cool material that cuts interesting gems. This agate comes from the
Green River Formation in southwestern Wyoming, northeastern Utah, and northwestern Colorado, from layers deposited in an series
of ancient lakes that geologists call Lake Gosiute and Lake Uinta, in the early and middle parts of the Eocene Epoch, between
around 53 and 42 million years ago. These rocks, in other words, formed in fresh water. The real Turritella is a group
of snails that live only in the ocean. The shells of Elimia are distinguishable from real Turritella by being
generally shorter and wider, but especially in having axial as well as spiral sculpture on the shell.
