Ancient Seas, North America, South Dakota, Pierre Formation, Late Cretaceous Period, ca. 83.6 to 72.1 million years ago. This is a stunning fossilized shell from the cephalopod Baculite compressus, with a straight, columnar structure. The exterior has developed rainbow iridescence from the shell's nacre surface (mother of pearl). Baculite, also known as "walking stick rock," is a heteromorph ammonite with a straight rather than spiraling shell. This piece is a fragment of larger shell that housed and protected the soft tissue of the baculite creature. The internal structure is visible on both ends and provides a unique look into the chamber that has been filled in with stone during the fossilization process. Size: 4.25" L x 2" W (10.8 cm x 5.1 cm)
