This confirms my suspicion that it takes a diapsid to know one

Perhaps the confusion here is the similarity to the term “theropod” which always refers to a diapsid except when it refers to Lenny. ben

Edit actually its a pariahsaur made famous by Jimi Hendrix in the line “scutes me while I kiss the sky.” and yes it is a diapsid.

Birds are also clearly diapsids and if every living amniote that isnt a mammal is a diapsid then birds are diapsid reptiles too.

This is where Lenny caustically suggested that I was a YEC for not knowing that turtles had been reclassified as diapsids with a secondarily anapsid appearing skull I hope that embryologically turtle skulls start off as diapsid and then change but I dont really know.

I think i’ve got this now: basal anapsid reptiles (which presumably gave rise to synapsid and sauropsid lineages) died out leaving no descendants. turtles, full diapsid reptiles closely allied to crocodiles, secondarily developed a seemingly (but not osteogenically identical) anapsid skull structure subsequently.

Edit perhaps this isnt the correct place to ask this question, but I’ve had difficulty with these high-in-the-classification-system words and perhaps someone knows the exact evolutionary definitions and how they compare to each other: “reptile”, “sauropsid” and “diapsid”.
