This is a great educational and decorator fossil!
Orthoceras are prehistoric cephalopods ("head-footed creatures") related to squid and octopus. This beautiful orthoceras (meaning "Straight Horn") fossil is from the Sahara Desert in Morocco. It dates to the Devonian Period - 395 to 345 million years old! These ancient mollusks had long, straight shells divided into chambers connected by a narrow tube, called the "siphuncle". These chambers were used to regulate buoyancy by exchanging gases and fluids, and the animal lived in the largest chamber.
This fossil has been polished and is 100% authentic. Polishing the stone makes the chambered shell remarkably clear and brings this ancient creature to life!
Approximately size: 8.5 to 9.5 Inches / 21 to 24 cm heigh and 2.75 to 3.73 inches / 6.5 to 9 cm wide. Weights about 4 lb / 2.5 kg.
Note: representative item.
