Description: | This freshwater fossil fish comes from Green River in the USA, one of the worlds 'super fossil sites'. It is the state fossil of Wyoming and was named after the first state geologist, Wilbur Clinton Knight. Knightia is a relative of the present day herring, and grew to a length of 10 to 25 cm. They lived in large shoals. The fish population died out very suddenly and large numbers were preserved as fossils in the fine-grained lake sediments. | 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 |
