Description: | Trilobites are very common fossils in Ordovician rocks. They grew in stages by moulting (shedding) their shells at regular intervals and growing a new one. This is why incomplete bits of the moulted shells of trilobites are much more commonly found than complete specimens. This specimen of Niobe is the moulted tail (pygidium) of the animal. | 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 |
