I feel like trying to reproduce a cladogram of dinosaurs from memory.
And, as always, when I say dinosaurs, I really mean just theropods. Because, really, who gives a shit about the other kinds? They're all dead.

How did I do? I'll score myself one of these days, maybe latter today or tomorrow. If not, probably never.
Not bad, not bad, but Dyrosauridae is a croc group. I think that's the only main problem I see.
ReplyDeleteMore minor issues:
I don't think there's a Sinornithosauridae. You're probably thinking of Saurornitholestinae. And the dromaeosaurid group you forgot is Unenlagiinae.
Therizinosaurs and oviraptorosaurs no longer group together; therizinosaurs are more basal.
Megalosauroidea takes precendence over "Spinosauroidea".
I can't say anything about sauropodomorphs or ornithischians from the top of my head, but you probably couldn't care less about them.
Yeah, what is that other Tyrannosauroid group? I was thinking I know Dryosaurus is an ornithischian, but I was pretty sure Dyro was the crocs too... I just remember Laelaps, so it's sort of confusing to me.
ReplyDeleteI WAS thinking of Saurornitholestines. My bad. And the unenlagiines. They used to be my favorite (Rahonavis), I forget crap quickly I guess.
Thanks for the update on therz, I wasn't paying attention when that happened, I guess.
I'm not touching the spinosaur/megalosaur thing with a 10 foot pole, I'm still counting that right.
And yeah, I don't care so much about non-theropods. Thanks for the corrections. It's not like I would've gone "hey, I'm going to plan out when I write another entry where I bother to plot out all my mistakes."
This works better. So how bad did I screw up Metaves?
Is it Dryptosauridae? I'm sure that's monotypic, however.
ReplyDeleteI wouldn't bother too much with the Megalosauroidea thing, either, taxonomy is scary if you get too close.
Metaves? Haven't looked at an up-to-date neornithine phylogeny in ages, sorry.
Yeah, thats what I was thinking of. Last time I checked it was just Lael... whoops, Dryptosaurus, but I don't know any other way Tyrannosauroids are divided up. I don't even know whats in there now.
ReplyDeleteBut then, they're dead, so who cares.
Birds have been pretty stable since... like, 2004 to 2006 or something. There was this giant genome sampling for Neoaves and the whole thing is pretty sorted out. It's awesome, you should check it out.
PLUS Paleognaths are pretty much done, and it looks like they lost flight three or so times. The T was for Tinamiformes, and I forgot Rheiformes, which are more basal than Casuariformes but more derived than Tinamiformes. Ratites hasn't really been fixed to exclude ostriches yet, though, so that's isn't right either.
