Description: | Peripetoceras freieslebeni was a nautiloid, an animal similar to the modern Nautilus that lives in the Pacific Ocean. It probably ate small sea creatures that lived on the reef that flourished in the warm water of the Zechstein Sea, 250 million years ago. The actual animal lived at the open end of the shell and had a set of tentacles much like a modern squid. The shell was filled with gas which allowed it to float at various depths in the water. It moved by squirting a jet of water through an organ called a siphuncle. This is a form of jet propulsion. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | fossils natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
