destructor. In 2002 however, a re-examination of the fossils by paleontologist Angela Milner showed that they most likely belonged to a subadult dromaeosaurid. Steve Sweetman examined five good specimens of fossil teeth and confirmed that they belong to Nuthetes destructor, and concluded that this species is a velociraptorine dromaeosaurid. If this placement is correct, it would have been one of the oldest dromaeosaurids known, the first to be described, and the first known from Britain. However, Rauhut, Milner and Moore-Fay (2010) pointed out the great similarity of the teeth of basal tyrannosauroid Proceratosaurus to the teeth of velociraptorine dromaeosaurids. The authors recommended caution when referring to isolated teeth from the Late Jurassic or Early Cretaceous to the Dromaeosauridae (explicitly citing Milner's 2002 study and Sweetman's 2004 study as examples of studies that identified isolated theropod teeth as belonging to dromaeosaurids), as these teeth might belong to proceratosaurid tyrannosauroids instead. According to Milner, Nuthetes can be diagnosed for having a tooth denticle size difference index ranging from 1-14 to 1-55.
