Evolutionary naturalism (as taught in American taxpayer-paid public schools) preaches that every living thing came from an unknown, unobserved common ancestor billions of years ago that—conveniently—left no fossil trace.

The pterosaur ("teer-o-sore") was a remarkable flying reptile of the pre-Flood, and possibly post-Flood world. They must have been an incredible sight in their day. Pterosaurs came in a wide variety. The largest had a wingspan of 40 ft (12m) Quetzalcoatlus named after a winged serpent god.
