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).
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).
The category called "coelurosaur dinosaurs" includes only actual dinosaurs (eg. tyrannosaurs). It does not include birds.
The fossil record does not support the dinosaur-to-bird idea. The fossil record does support the pterosaur-to-bird idea.
