Description: | Foraminifera are sea-living microfossils (microscopic-sized fossils) that secrete a hard calcareous (made of calcite) skeleton known as a test. Loftusia is quite large and has a flat, spirally coiled shell. It lived on the floor of a warm shallow sea, often in such great numbers that the tests later formed limestones like the one shown here. Foraminifera changed (evolved) very quickly through time. This means that they can be used to identify different rocks layers, as distinct species are only found in certain layers. | 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 |
