WCraterosaurus was a genus of stegosaurid dinosaur. It lived during the Early Cretaceous around 145-136 million years ago. Its fossils were found in the Woburn Sands Formation of England. Craterosaurus may actually be a junior synonym of Regnosaurus, but only one fossil, a partial vertebra, was recovered.
WDakosaurus is an extinct genus within the family Metriorhynchidae that lived during the Late Jurassic and Early Cretaceous. It was large, with teeth that were serrated and compressed lateromedially. The genus was established by Friedrich August von Quenstedt in 1856 for an isolated tooth named Geosaurus maximus by Plieninger. Dakosaurus was a carnivore that spent much, if not all, its life out at sea. The extent of its adaptation to a marine lifestyle means that it is most likely that it mated at sea, but since no eggs or nests have been discovered that have been referred to Dakosaurus, whether it gave birth to live young at sea like dolphins and ichthyosaurs or came ashore like turtles is not known. The name Dakosaurus means "biter lizard", and is derived from the Greek dakos ("biter") and σαῦρος -sauros ("lizard").
WGyrodus is an extinct genus of pycnodontiform ray-finned fish that lived from the late Triassic (Rhaetian) to the middle Cretaceous (Cenomanian).
WNeovenator (nee-o-ven-a-tor), which means "new hunter", is a genus of allosauroid dinosaur. At the time of its discovery on the Isle of Wight, United Kingdom, it was the best-known large carnivorous dinosaur from the Early Cretaceous period of what is now Europe.
WPlatypterygius is an ichthyosaur of the family Ophthalmosauridae. It is most closely related to the genera Caypullisaurus and Brachypterygius. The ichthyosaur lived from the Early Cretaceous (Hauterivian) to the earliest Late Cretaceous (Cenomanian) and had a cosmopolitan distribution.
