sauropsid

Many years later euryapsids had vanished into the lepidosaurs sphenodon, snakes and lizards-all diapsids as a secondary change, and then there was the term “sauropsid” which I saw for the 1st time at AMNH which gathered together all non synapsids and non turtles.

The last change is circulatory -- from the sauropsid blood system which still permits some mixing of venous and arterial blood, to the pteropsid system we see in Earthly birds, which supplies nothing to the brain but oxygenated arterial blood.

In our hypothetical scenario, perhaps it was the island population that was destined to give rise to the sauropsid reptiles that’s everything we call reptiles today plus birds, while the mainland population eventually gave rise to the mammals.

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”.
