"last I read , stu, dino to bird evolution was not cut and dried, even among evolutionists. and though you give an ardent affirmation ,even you admit to guessing, given the definite differences."

1) ANOTHER misrepresentation of my argument. The differences between deciding the dividing line will be subtle, as both morphotypes of bird/dinsosaur grade into one another. I am guessing as I don't work directly on these particular dinosaurs, but do know people who do and try to keep up with progress. In fact, the differences are so small that to all intents and purposes they don't really exist, and scientists pursue the studies for taxonomic reasons (which is fair enough).

2) Those not agreeing with an dinosaurian origin of birds are very much in the minority and tend to be ornithologists. I saw one of these chaps speak last year and his argument was as full of holes as yours are, and there was no real point in arguing. He turned up and talked though, so good on him. I suggest if you want to debate these points, read up more.
