Summary

Here is a summary of the basic ideas of this site. This is a work in progress.:

Birds developed in a lineage from proto-pterosaurs (eg. cosesaurus)

to pterosaurs (eg. pterodactyls)

to primitive pygostylia birds (eg. enantiornithes)

to modern flying birds (neognathae) and modern flightless birds (palaeognathae).

AND

Primitive pterosaurs (rhamphorhynchids) developed into long-bony-tailed feathered creatures (eg. dromaeosaurs) which went extinct. Advanced pterosaurs (pterodactyls) developed into short-tailed feathered birds (Pygostylia).

AND

The category called "coelurosaur dinosaurs" includes only actual dinosaurs (eg. tyrannosaurs). It does not include birds.

AND

The fossil record does not support the dinosaur-to-bird idea. The fossil record does support the pterosaur-to-bird idea.
