Is Archaeopteryx a feathered dinosaur?

Practically all paleontologists think of Archaeopteryx as the first bird or the missing link between dinosaurs and birds. The fossil is used as a showcase for evolution.

However, Chinese paleontologists now challenge this classification, and instead make a case that Archaeopteryx is a feathered theropod dinosaur.1 This belief is based on the finding of an Archaeopteryx-like fossil in China called Xiaotingia zhengi (figure 1), the affinity of which is supposedly with the early theropod dinosaurs and feathered dinosaurs. The new fossil is said to resemble theropod dinosaurs and, just like Archaeopteryx, it has teeth, claws on its wings, and a vertebrate tail. But the new fossil still has many features of birds, such as: feathers; small size; boomerang-shaped wishbone; and features of enantiornithines, unique fossil birds.

Based on questionable phylogenetic analysis

It seems that the classification of Archaeopteryx and Xiaotingia zhengi depends upon the traits selected for the cladistics analysis.

To back up their claim, the Chinese paleontologists have used numerical phylogenetic analysis, cladistics, that compares anatomical features of many individuals. The idea is that the more similar the fossils, the closer they are related by evolution. But the researchers also admit: “It should be noted that our phylogenetic hypothesis is only weakly supported by the available data.”2 They go on to add that other phylogenetic analyses have demonstrated just the opposite, that Archaeopteryx is a basal bird: “Although Archaeopteryx is placed within the Avialae [basal birds] by nearly all numerical phylogenetic studies…”3 In order to attempt to weaken the cladistics data that says Archaeopteryx is a bird, the Chinese paleontologists claim that some of the traits used in the cladistics analysis are questionable. So, it seems that the classification of Archaeopteryx and Xiaotingia zhengi depends upon the traits selected for the cladistics analysis.

Perhaps this is one of the reasons that cladistics analysis has been claimed to be subjective by some researchers.4,5 This new designation for Archaeopteryx supports this belief. Cladistics is a poor tool by which to classify unique fossils as feathered dinosaurs,6,7 or any fossil for that matter.8 Michael Balter, in Science, acknowledges that the Chinese paleontologists admitted to the weak statistical connection for claiming Archaeopteryx is a feathered dinosaur, but adds: “And other researchers say such ambiguities in classification are not surprising.”9 This shows the widespread ambiguity of cladistics analysis.

The claim is controversial

This new designation of Archaeopteryx is of course based on the opinion of four Chinese paleontologists, who are challenging a major icon of evolution. Lawrence Witmer states:

Many of the true extinct birds found in China have unique features that are shared by some dinosaurs, but they are still birds.
“For the past 150 years, the famous feathered fossil species from Bavaria in Germany has been a symbol of evolution, a textbook example of a transitional fossil and, above all, the oldest and most primitive bird. … The finding is likely to be met with considerable controversy (if not outright horror), in part because of the historical and sociological significance that Archaeopteryx has held, but also because it may mean that much of what we thought we knew about the origin and early evolution of birds will need to be re-evaluated.”10

Could ‘feathered dinosaurs’ be unique fossil birds?

Because of all the subjectivity, I lean toward the idea of several ornithologists that ‘feathered dinosaurs’, those with true feathers and not probable collagen fibers,11 are really unique, fossil birds.12–14 Some of the feathered dinosaurs were first classified as birds, showing the equivocal nature of the classification.15 Many of the true extinct birds found in China have unique features that are shared by some dinosaurs, but they are still birds. True birds are also found with so-called feathered theropods, suggesting that maybe all the animals in the location are types of birds. And even one cladistics analysis on the subject, if it can be trusted, concluded that ‘feathered dinosaurs’ are in fact birds.4

Wouldn't a feathered creature be a bird by definition? Most people would think of a feathered creature as a bird. Ancient Roman soldiers had leather strips hanging from their waists, called feathers, because their national icon was the eagle.

Shaun Doyle responds

While feathers may be an essential feature of birds, that does not necessarily mean feathers are only found on birds. If ‘feathered dinosaurs’ is a legitimate category, then other features that distinctive of birds (e.g. the unique avian lung system) still provide ways of distinguishing between birds and ‘feathered non-birds’. As a ministry we don’t deny that feathered dinosaurs might have really existed (it’s certainly not beyond God’s capacity to create feathered dinosaurs), though as far as the evidence stands at present Mr Oard is certainly justified in arguing that ‘feathered dinos’ found with real feathers are most likely birds.

This whole thing is so stupid! All you have to do is look at living Hoatzins! There's your Archaeopteryx. Only the beak is different, but we already know environmental factors can affect beak shape. Just look at Darwin's Finches!

I have noted that Mr. Oard has become a special target to be lambasted on the internet. I have read a book or two that he wrote along with two DVD power point presentations. I enjoy his style and his research. I look forward to his latest video.

Mr. Oard got to the point. That is the disagreement among the evolutionists concerning Archaeopteryx based on the on going work of Chinese scientists and their Xiaotingia zhengi discovery. Indeed Archaeopteryx was supposed to be one of their "divine" missing links. It was pictured in many of the text books that I used while teaching in public schools. The concept of paleontologists using “...numerical phylogenetic analysis, cladistics, that compares anatomical features of many individuals” is interesting. Such studies and differences should cause disagreements among real scientists. I recall that awhile back China was sending fake fossils out and National Geographic fell for them. While they criticize Mr. Oard, I have never heard Darwin’s bull puppies on the net nip at National Geographic for publishing fake fossils as real missing links. Can we say that Archaeopteryx is now another missing link - still missing! Prayer answered. Thanks for the good news Mr. Oard, and hang in there.

Thank-you for this article Mr Oard. I have to say that since I viewed Dr Werner's 'living fossils' DVD the whole dino to bird missing link fantasy has become a complete yawn to me. Common bird fossil 'kinds' alongside dino fossils in the same rock makes contemporaneous existence a fact and dino to bird evolution a redundant myth. Thanks to all my CMI heroes and brothers who work so hard to dispell these fiction as fact pseudoscience dogmas.
