The name of these ancient mollusks comes from the Greek words orthos (straight) and ceras (horn). Orthoceras are relatives of Ammonites, but their shell is not twisted into a RAM's horn, but straightened by a cone (and the length of such a shell could reach two meters).
For the first time these strange animals were discovered by the famous naturalist Carl Linnaeus in 1741. Because of their straight shape they are sometimes called "Eland spears" - on the island of Eland near the coast of Sweden, where one of the locations. Orthoceras inhabited the water depths more than 200 million years ago and led a bottom-dwelling lifestyle, as such a non-compact shell was not maneuverable enough to live with it in the water column, where large and dangerous Ki hunted every now and then.
Paleontological reference
Genus Orthoceras (Orthoceras) belongs to the class of cephalopods. These are ancient invertebrates with many tentacles, and their modern closest "relatives" are squid, cuttlefish and Nautilus. They existed from the Ordovician period (485-443 million years BC) to the Triassic (250-200 million BC), giving way to more biologically perfect Ammonites.
The shell of the orthoceras is a straight cone divided internally into many chambers. These chambers could be filled with air or liquid - with their help, the mollusk could adjust its vertical position in the water. The soft body of the mollusk itself was in the chamber farthest from the sharp end-the living chamber. In case of danger the animal could draw in its head and tentacles.
Our beauty is decorated with handmade tentacles, Hawkeye and rock crystal.
