Quote:The skull of the Alligator Snapping Turtle at right above in common with the Loggerhead Sea Turtle skull at left has an Anapsid Skull which means it lacks temporal fenestra or windows, identifying it as from the most primitive subclass of reptiles that appeared approximately 340 million years ago during the Carboniferous period.

Quote:Synapsids which have a single temporal window the most famous of which is the Dimetrodon, a class which appeared in the late Permian and became extinct in the Permian Catastrophe which wiped out 95% of all species 252 million yrs ago.

Quote:And Diapsids a class which includes modern lizards, snakes and birds which have two temporal fenestra, all evolved from the single archtype that lives on in the order Testudines which includes all shellbacks, turtles, tortoises and terrapins Smile InternetWiki.

We are gonna say the Snapping Turtle's habit of remaining buried under mud for months at a time enabled it to escape the ravaging Solar Flares and the era of boiling that came in their wake, which indeed precipitated the Permian Extinction.

This species survived the Permian and Cretaceous Catastrophes.

Quote:Proganochelys Quenstedti is the oldest stem turtle species with a complete shell discovered to date, known only from fossils found in Germany and Thailand in strata from the late Triassic, dating to approximately 210 million years ago.
