(Birds are dinosaurs, crocodiles arenât) note the âclosest living relativesâ
âBrother, am I not your relative?â

I actually just learned this recently, but dinosaurs differ from reptiles in that dinosaurs have legs that are under their bodies whereas reptiles have legs that splay out to the side. So all mammals, and birds, with legs directly under their bodies are probably more closely related to dinosaurs then reptiles.
No. Tetrapods and reptiles diverge well before dinosaurs. All dinosaurs are diapsids as compared to mammals, which are synapsids. A dimetrodon (the one with the big sail) is not actually a dino and is more closely related to humans than it is to dinos.
Forgive my ignorance on the subject, but huh?
Clearly I missed a briefing somewhere. I thought that crocodiles were from that era, or is that the joke that Iâm somehow missing?
The joke is that birds arenât only related to dinos, but are dinos themselves.
Yes and the cruel part is⌠Pterosaurs are not Dinosaurs!
So, itâs a joke about the fact that both are essentially dinosaurs?
⌠nope, I got nothing âŚ
This is dumb as rocks
The most charitable interpretation is âwell crocodiles didnât change in the last 100 million years but birds did so that means maybe crocs are closer since birds evolved to get farther awayâ
Thatâs dumb because both birds and crocodiles have been changing the whole time. Just because crocs look more similar to their fossils, doesnât mean they havenât been evolving/drifting/etc.
Same thing any time someone talks about âsharks havenât changedâ. Itâs dumb.
This is some dunning Kruger shit.
It has nothing to do with if the said animal were evolving or not. Birds and Crocodilians are the only living animals of the Archosauria clade. Since birds are dinosaurs, technically they arenât their relatives. So Crocs are the closest living relatives of dinosaurs (and birds), since they belong in the same clade and shared a common ancestor more recent than anyone else alive.

Though, isnât being part of a group the closest you can get in terms of relatedness?

Yeah, itâs like being related to your family. Most people would consider your relatives to be related to you.

Are octopus related to octopus? I mean technically theyâre 100% related, but also they arenât related as related implies not being. Depends on your interpretation.
