WMegalocephalus is an extinct genus of baphetid amphibian from the late Carboniferous of the British Isles. It contains two species, M. pachycephalus and M. lineolatus.
WNeithea is an extinct genus of bivalve molluscs that lived from the Early Jurassic to the early Paleocene, with a worldwide distribution. Neithia sp. are inequivalve. That means that the two valves are not the same shape, the right valve being strongly concave and the left valve being flattened or concave. Sculpture consist of alternating strong and weaker radiating ribs.

WPhymosoma is an extinct genus of echinoids that lived from the Cretaceous to the Eocene. Its remains have been found in Asia, Europe, and North America.
WTerebratula is a modern genus of brachiopods with a fossil record dating back to the Late Devonian. These brachiopods are stationary epifaunal suspension feeders and have a worldwide distribution.
