abstract:Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria."Owens, 1842.
Despite this, the finding very strongly suggests something of the dinosaurclassification, that also fills in a "missing blank" between them and their earliest relatives.
