 after over a century of new discoveries, it is even less secure than
 _Troodon_'s type fossil in Troodontidae(sp).

Being above the family group of ranks, Dinosauria does not have a type specimen, not even indirectly.

(In animal nomenclature, species have type specimens, genera have type species, and so on; superfamilies have type families; taxa at higher ranks lack types, which is often a distinct disadvantage.)
