ttyo888 Posted December 23, 2009 Share Posted December 23, 2009 I am just curious about the structure of that hook at the wrist... Is it like a panda's thumb and can be moved independently of the hand? Link to comment Share on other sites More sharing options...
Mokele Posted December 23, 2009 Share Posted December 23, 2009 It's not actually a bone; apparently it's called the styliform cartilage, an addition to the wrist which can be moved to erect the patagium. http://si-pddr.si.edu/dspace/bitstream/10088/4761/1/VZ_rwt5.pdf Link to comment Share on other sites More sharing options...
ttyo888 Posted December 23, 2009 Author Share Posted December 23, 2009 so the squirrel can fold back this bone at will? so can we imagine when the time and ecology pressures are right, maybe this bone might become a longer until this creature can fly?

Mokele Posted December 24, 2009 Share Posted December 24, 2009 http://www.jstor.org/pss/1382860 Apparently, it can be both erected and folded back voluntarily. Link to comment Share on other sites More sharing options...
ttyo888 Posted December 24, 2009 Author Share Posted December 24, 2009 Wow imagine what this creature will become in the future.. A real "Flying" Squirrel once that piece of bone becomes longer. Link to comment Share on other sites More sharing options...
