Newtonsaurus
"Newtonsaurus" is the informal name given to an as yet undescribed genus of dinosaur from the Late Triassic. It was probably a ceratosaur, which lived in what is now the United Kingdom. The type species is "N. cambrensis", originally coined as Zanclodon cambrensis,[1] although it has usually been referred to Megalosaurus, due to the taxonomic difficulties associated with Zanclodon. It is based on a mold of a dentary from Rhaetian-age beds in Wales (hence the species name), and is one of the relatively few dinosaurs known from the time near the Triassic-Jurassic boundary.
Paleontologists have avoided using the name since its appearance in 1999 in private publications, although "Zanclodon" cambrensis or Megalosaurus cambrensis have both been used for this taxon.
