Nuthetes

Name: Nuthetes (Monitor).
Phonetic: Nu-thet-eez.
Named By: Richard Owen - 1854.
Synonyms: Megalosaurus destructor.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Dromaeosauridae, Eudromaeosauria, Velociraptorinae.
Species: N. destructor (type).
Diet: Carnivore.
Size: Highly speculative given that this genus is in essence a tooth taxon. Comparisons to dromaeosaurid dinosaurs however indicates that the holotype came from a dinosaur roughly 2 meters in length.
Known locations: England - Lulworth Formation, Cherty Freshwater Member. Possibly France.
Time period: Berriasian of the Cretaceous.
Fossil representation: Teeth and a fragment of jawbone.

       Originally thought to be a juvenile of a species of Megalosaurus, Nuthetes was later established as a distinct genus. Today Nuthetes is thought to represent a possible dromaeosaurid dinosaur, but the key word here is ‘possible’. So far Nuthetes is only known from teeth and a fragment of jawbone, making such things as an exact indification very difficult. It is also hard to estbalish any further details and the only lead that paleontoligsts have is that the Nuthetes material represents a possible dromaeosaur. If true than comparisons to other dromaeosaurs indicate that Nuthetes, if a dromaeosaur, would have been about two meters long.
       There is also some confusion with the genus Dromaeosauroides from Denmark, as some larger fossil teeth that have been referred to Nuthetes may actually belong to Dromaeosauroides. Likewise, other teeth from Jurassic aged rocks may actually come from proceratosaurid dinosaurs (those related to Proceratosaurus). Overall, Nuthetes is considered to be a dubious dinosaur genus as it will be very difficult to infer further fossil remains based only upon the teeth.
