> Why not just have the "genus" name be _the_ name?
Because it is never really clear if it is monotypic or not.
For example, you might say _Baryonyx_ is monotypic, but others might consider
it to have two or even three species (_tenerensis_ and maybe _lapparenti_).
There are thousands of other examples (_Triceratops_? _Gorilla_?
_Pterodactylus_? _Tyrannosaurus_? etc.)
You can't objectively say that a genus is monotypic, so this cannot be a straightforward method for conversion.
