"not only capable" should be "It is not only capable".
"get away" should be "getaway"
"Another adaptation[...]autonomy".
That sentence is overly long. You also confused "autonomy" with "autotomy". (Think of the Pokemon move "Autotomize".)
"but certainly not least important" is extraneous.
"chewed up" I recommend "chewed-up".
"minimum" should have "temperature" or "body temperature" after it.
"gallop away from" should be "gallops away from".

Argentine tegus seems pretty close to this in physiology, and those live for 15-20 years.
It's interesting to see how many Teguloterguformes end up looking like dinosaurs in some way, even ones that aren't thornbacks/Fermisaurs.

Coolsteph, fixed it.
