It seems that Kuehneosaurs used their rib 'wings' more as parachutes than for gliding. Would this be to escape flying things that were in the trees too? Like, say, pterosaurs? Or perhaps the analysis done needs to be used on the flying lizards of today to see if they get similar results or different. They would need to restrict their modeling to the exact same methodology as they used here. Then compare what they got to what the flying lizards do today.
