Cochlioceras

Cochlioceras was an ancient group of sea creatures that lived millions of years ago during a time called the Ordovician period. This group belonged to a larger family known as baltoceratid, which were types of straight-shelled cephalopods. These creatures existed for around 14 million years, from about 478 to 464 million years ago.

Fossils of Cochlioceras have been found in places that are now part of Europe, the U.S. state of Vermont, and China. Studying these fossils helps scientists understand what the oceans were like long ago and how life has changed over time. Even though these animals no longer exist, they give us clues about the history of life on Earth.

Taxonomy

Cochlioceras was named by Eichwald in 1860. Its main example species is called Cochlioceras avus. Scientists later placed it in a group called Baltoceratidae. This group was moved from one bigger family to another by researchers in different years.
