On the Alleged Dinosaurian Ancestry of Birds

"The idea that birds descended from dinosaurs was first suggested by Thomas Huxley in 1868 on the basis of skeletal similarities between Archaeopteryx lithographica and Compsognathus longipes, a chicken-size coelurosaur recovered from the same formation as Archaeopteryx...

By the mid-1990s, Ostrom’s theory had become “practically dogma among vertebrate paleontologists.” Thus, even before the recent finds, one was assured: “Birds are dinosaurs. And not all dinosaurs have gone extinct; one group, the birds, survives..." Full text: On the Alleged Dinosaurian Ancestry of Birds, Ashby L. Camp

["...The presence of short, fibrous structures on a Sinosauropteryx fossil is often interpreted as "protofeathers" despite the fact that the existence and structure of these ancestral feathers are completely hypothetical.

In another problematic find, the fossil Protoavis is considered to be more similar to modern birds than Archaeopteryx but is 75 million years older. this causes significant problems for the theropod theory because the common ancestor would need to be much older than the earliest known dinosaur Eoraptor...

The development of the bird lung is another major issue because no suitable ancestor exists from which the lungs could have developed...The evolution of birds is an area where scientists have found little to agree on. The special creation of birds and their subsequent variation explain the evidence much better."]  Evolution Exposed, Second Ed.
