Re: Magnapaulia, "new" lambeosaurine from Baja California, Mexico



Good point. Unfortunately, this doesn't happen much anymore. Psittacosaurus 
species are more closely related than the hodge podge that Iguanodon covered 
until a few years ago. I think that splitting genera, whether the ranks have 
meaning or not, does increase the apparent diversity of a taxon, because we 
always see the genus name first.

I'd argue the opposite--having genera with many included species is
deceptive for the average person. How many average science enthusiasts
know that "Psittacosaurus" is a category of animals containing dozens
of unique and distinct species? Including this diversity in the single
label "Psittacosaurus" effectively hides that diversity from everyone
but specialists.
