Description: | This is the cast of the inside of a spirally coiled nautiloid shell that shows the inside walls and hollow chambers. The original cast was replaced by phosphate minerals that formed in a shallow, warm seas when little or no sediment was being deposited. Cymatoceras swam using jet propulsion, squirting water from its body, which pushed it backwards. It was a carnivore that fed mainly on crustaceans (shrimps and crabs) and fish that it caught in its 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 |
