Description: | Gonatites were similar to the coiled-shelled ammonites but more primitive. The inside of the shell was divided up by septa (walls) into several separate chambers. The animal was similar to a squid and lived in the outermost chamber and the smaller chambers were filled with gas so that the shell was buoyant. Muensteroceras lived near the surface of the sea and swam using jet propulsion, forcing water out of its body. It was carnivores and fed mainly on shrimps, crabs and fish they caught in their tentacles. | 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 |
