bro lemme fucking tell you you have no fucking ideaThoughts on this from people who know more about paleontology? Are we too quick to classify something as a new discovery? Are we classifying baby dinos as different animals? Am I crazy?
I have run in so much nomenclature sludge and classification issues i would have probably hanged myself if i didn't like palaeontology. For example, horsetails today are classified in the genus Equisetum. And, a while ago, some schmuck found a fossil horsetail that looked somewhat similar, and he named that horsetail Equisetites. Simple, right ?
Well the issue is Equisetites got a whole buncha species added to it. Cool. But these species are really really different from each other and now the genus is widely considered paraphyletic (made up of unrelated species that do not form a biological/evolutionnary group), containing both very primitive stuff and things that look like present day forms. Buuuut since it's old shit and very complex no one ever really bothered sorting it out because it seems way too complex. It gets complicated when you get to later species, since a lot of them are basically the same kind of stuff as the modern-day Equisetum. And with the current generic diagnosis (=what defines a genus) of Equisetites being essentially the same, you end up with a problem : which genus do they belong to ?
And that's were opinions "DIFFER". It's a shitshow, and no one seems to be able to actually sort it out, so you have a shit ton of species that have 2 names and are never classified properly or get assembled into a single monophyletic group but belong to 2 different species. I can essentially boil it down to 2 arguments :
"X species is basically indistinguishable from the modern day genus"
against
"X species is too old to belong to the modern day genus
I said fuck off you niggers and chose Equisetum for modern-looking species because i'm done dealing with that shit
