Together with " Megalosaurus " and " Hylaeosaurus ", it was one of the three genera originally used to define Dinosauria.
32.
Dinosauria was a massive, diverse clade which existed for hundreds of millions of years ( and still does, in the form of birds ).
33.
The genus is commonly misspelled " Aepysaurus "; both editions of " The Dinosauria " and a major review use this misspelling.
34.
However, this synonymy was rejected in the 2004 edition of the " Dinosauria ", with " Stephanosaurus " being tabulated as dubious.
35.
A year later, when Owen coined the name Dinosauria, he did not include " Cetiosaurus " and " Cardiodon " in that group.
36.
Towards the end of the twentieth century, the so-called Dinosaur Renaissance took place in which a vast increase in scientific attention was given to the Dinosauria.
37.
As such, the Dinosauria was no longer seen as a scientific grouping, and " dinosaur " was reduced to being a popular term, without scientific meaning.
38.
Michael Benton classifies all dinosaurs within the Series Amniota, Class Sauropsida, Subclass Diapsida, Infraclass Archosauromorpha, Division Archosauria, Subdivision Avemetatarsalia, Infradivision Ornithodira, and Superorder Dinosauria.
39.
However, some controversy remains over whether Megalosauridae should be considered its own distinct group, and dinosaurs in this family remain some of the most problematic taxa in all Dinosauria.
40.
The raising of the Dinosauria to class rank found less support, perhaps largely due to increasing use of phylogenetic taxonomy among vertebrate palaeontologists, in which ranks are entirely abandoned.
