Description: | Orthis redux is a brachiopod (lamp shell) from rocks of Silurian age, approximately 440 to 420 million years old. The Budleigh Salterton Pebble Bed is Triassic, and approximately 240 million years old. The Orthis fossils, in a piece of Silurian rock, have been incorporated in a pebbly conglomerate (coarse sandstone) during the Triassic. The orthis fossils are much older than the Triassic conglomerate that they were found in. | 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 |
