What scientists once thought were protofeathers (the so-called precursors of bird feathers) on pterosaurs might just be tough fibers from pterosaur wing membranes that have unraveled and decayed. While that evidence isn’t sufficient to claim that dinosaurs did or did not have feathers, this finding challenges the idea of feathered dinosaurs since evolutionists believe that pterosaurs and dinosaurs shared an ancestor. They say it would be unlikely that such complex structures as protofeathers developed separately in the two different groups.
The argument challenges secular scientists who claim that birds evolved from dinosaurs, because bald pterosaurs have many implications and weaken the idea of feathered dinosaurs. But this isn’t a problem for biblical creationists who know that God created birds on day five and dinosaurs on day six of creation week. Dinosaurs and birds are two separate and distinct kinds of animals. Both marvelous creatures with their unique features were designed by a magnificent Creator, not the result of millions of years of random changes.
