Ammolite and Ammonite Knowledge Assessment

The video explores the fascinating history and formation of ammonites, ancient cephalopods with spiral shells that are now extinct. Their fossilized remains, found worldwide, sometimes transform into the vibrant gemstone ammolite, particularly in southern Alberta, Canada. This transformation is rare due to the instability of aragonite, the mineral composing their shells. Unique geological conditions in the Bearpaw Formation, including rapid burial and high pressure, may have preserved the aragonite. Ammolite's beauty arises from light diffraction, creating rainbow colors. The video concludes by highlighting ammolite's rarity and inviting viewers to explore more about minerals and gems.

What were ammonites, and what is unique about their fossils in southern Alberta?

• Ammonites were ancient birds, and their fossils are found worldwide.

• Ammonites were ancient reptiles, and their fossils are made of gold.

• Ammonites were ancient cephalopods, and their fossils in Alberta have turned into rainbow-colored gems.

• Ammonites were ancient fish, and their fossils are found only in Alberta.

What mineral primarily composed the shells of ammonites?
