Orthoceras is a cephalopod that first appeared approximately 500 millions years ago, and then became extinct approximately 385 million years ago. The name means "straight horn", referring to it’s characteristic of a long, straight, conical shell. The preserved shell is all that remains of this ancestor of our modern-day squid.
This authentic orthoceras fossil makes a great addition to any fossil/rock/mineral collection, and looks great in the classroom. Have students pass it around and study its markings, and maybe draw what they imagine the creature might look like. Also makes an inexpensive, gift, stocking stuffer, or fun and unique party favor!
