Another minor detail to note is that the group Dinosauria was named by Owen 
first, when there was
no Dinosaurus. Dinosaurus was named in 1845. The naming of higher level taxa 
without a name-giving
genus is a common thing (Saurischia, Ornithischia, Theropoda, Predentata, 
Oviraptorosauria to name
a few) has always been a common practice.
