Description: | During the Ordovician period, brachiopods (lamp shells) were the most abundant form of shellfish living in the sea. This is very different from present day seas where bivalves are dominant and brachiopods are comparatively rare. There are several different kinds of fossil brachiopods in this Ordovician siltstone. The three largest examples (towards the left of the rock) are of a brachiopod called Nicolella. They have prominent fan-like ribs. | 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 |
