What is a baculite?

If an Ammonite is a "coiled" shell, a Baculite is its straight-shooter cousin. The name actually comes from the Latin word for "walking stick," which makes sense the moment you see one.

1. The "Straight" Squid

Baculites were prehistoric cephalopods (squid-like creatures) that lived around 70 to 90 million years ago. Unlike their spiral relatives, they lived in long, straight, cone-shaped shells. Some were only a few inches long, while others grew to be over six feet!

2. Nature’s "Rainbow Staff"

Just like Ammolite, some Baculite fossils from the Alberta and BC regions are found with incredible iridescence. When the light hits them, they flash neon pinks, greens, and golds. In the collector world, these are often called "Rainbow Baculites," and they are just as rare as gem-grade Ammolite.

3. The "Lace" Patterns

If the outer "skin" of the shell has worn away, you’ll see complex, wavy lines that look like frosted ferns or lace. These are called Suture Lines. They aren't carvings; they are the natural internal walls where the animal’s body once attached to the shell.
