Only a bird » Pharyngula

Only a bird » Pharyngula:

Another feathered dinosaur has been found in China, prompting Ken Ham to dig in his heels and issue denials.
Yet another supposed “feathered dinosaur” fossil has come to light, again in China. (Dr. Elizabeth Mitchell, AiG–U.S., reported on another Chinese fossil of a supposed feathered dinosaur in April 2012) Now, one headline described the fossil as “almost birdlike,” and the authors of the report in Nature Communications note many features the fossil shares with living birds, particularly those that live on the ground. In fact, Dr. Elizabeth Mitchell and Dr. David Menton (AiG–U.S.) both examined the photos of the fossil and the criteria the authors used in classifying the fossil as a dinosaur. They agreed that it is a bird, not a feathered dinosaur.
Oh, really? It’s just a bird? Take a look at this image of Eosinopteryx, and you tell me.
Notice a few things about this animal: it’s got teeth. The forelimbs have clawed digits. It has a long bony tail. It lacks the bony keel that anchors breast muscles in modern birds.
The only thing that might cause you to question its dinosaur nature (and it’s a criterion that’s proving more and more inappropriate) is that lovely gray fringe of feather impressions that surround the whole fossil. And look at those forelimbs! It looks like it has stubby wings. It does not, however, have the skeletal and muscular structure to allow for extended flapping flight, and the wings are way too short for it to have been an adequate flyer.
But Mitchell and Menton and Ham looked at that and said ‘ALL BIRD’. They’re idiots.
Ham goes on: there are no transitional forms, he squeaks, there can be no transitional forms, transitional forms don’t exist…all while looking at a winged, feathered reptile with teeth and claws and a bony tail.
The fossil record doesn’t reveal any kind of dinosaur-to-bird evolution—and it certainly does not show a molecules-to-man evolution. We have no proof of transitional forms, and we won’t. God’s Word says clearly that He created animals and plants according to their kinds (Genesis 1). Through genetic loss and other factors, new species have emerged over time—but birds are still birds and apes are still apes. Nothing in the history of biology has legitimately shown that dinosaurs could develop the genetic information to evolve into birds.
Pitiful. Pathetic. I’d like to see a creationist sit down in front of me with that illustration and try to defend the claim that it’s only a bird.
