Don't be so sure about this. There is considerable bias in the fossil record
toward more recent forms (e.g., Cenozoic). As more dinosaur horizons open up,
more new dinosaur genera are described. And don't forget that modern birds,
which are dinosaurs as well, are the most diverse tetrapod subgroup, beating
mammals by more than two to one.
