Archaeopteryx is an extinct transitional form between reptiles and birds. It is known in popular culture as the first bird. Archaeopteryx had features of both reptiles and birds like feathers, wish bone, teeth, etc.
Creationist claims Edit
Creationists claims include that archaeopteryx was a hoax and it was fully a bird and not a transitional form. Answers in Genesis has quoted palaeontologist Alan Feduccia, "Paleontologists have tried to turn Archaeopteryx into an earth-bound, feathered dinosaur. But it's not. It is a bird, a perching bird. And no amount of 'paleobabble' is going to change that."  Feduccia has described this preposterous and he was the one who coined the phrase archaeopteryx is the Rosetta's stone of evolution.
