During the Mesozoic (~245-65 million years ago) the ammonites, a relative of the modern chambered nautilus, flourished and are an important part of the fossil record, but they became extinct at the end of the Cretaceous at the same time as the dinosaurs.

Are Turritella still alive?

Answer 1: There certainly are turritellas living today- several hundred species! Many of them look very much like the fossil turritellas, which have been around since the Cretaceous Period. If you want to see one “on” the whole shell (ha ha), here is a website where you can see images of a living turritella.

Why is ammolite so rare?

Ammolite is actually one of the rarest gemstones in the world. This is because it is unique to a geological deposit known as the Bearpaw Formation. The limited areal extent of this deposit is the primary reason why ammolite is so rare. Estimates suggest that there may only be around six to eight years of mining left.
