A juvenile Dimetrodon giganhomogenes in an Early Permian forest of Walchia piniformis pines. The youngster looks over in astonishment as a Captorhinus aguti makes its escape beneath the safety of a fallen stump after it broken its tail off in the predators jaws.

Friend of mine printed my profile pic. It's the skull of Captorhinus, an early "reptile" from the Permian of Oklahoma. In my thesis, I studied its skull sutures to learn more about the evolution of temporal openings. You can read more about it here:

Mail call! Just got FOUR 289-million-year-old Captorhinus jaw fossils from Richards Spur, Oklahoma. These little guys were scurrying around before dinosaurs were even a thing! Swipe to see some serious Permian chompers. #FossilFriday #Paleo #Permian #RichardsSpur #FossilCollector #fossil

Mummified fossil reptile remails, dated to approximately 289–286 million years ago, show that early amniotes (a group that includes reptiles, birds, and mammals) breathed by moving their ribcages, according to a paper in Nature. go.nature.com/4ctrOIx #Paleosky 🧪
This is figure 3, which shows histological thin sections through the mummified articulated Captorhinus specimen (ROMVP 88565, TS01782 and TS01993).

Every breath you take is an ancient inheritance. The rise and fall of your chest, the intercostal muscles pulling your ribs outward, the rush of air into your lungs—this mechanism is so familiar it barely registers as remarkable.
