me said:So what part of the "this study is full of gaping flaws" discussion did you miss?
1) Their estimates are based on out of date cherry picked data from the beginning of the last century. Data not even based on complete fossils.
2) Their estimates ignore the most avian dinosaurs, skewing their data.
3) Their estimates ignore even the obvious early birds like Archy... totally ruining any objectivity in the data.
4) this study ignores the evidence that Alligators and other Crocodilians have bird like breathing not lizard like breathing. That is they have uni-directional airflow not tidal airflow.
5) This study ignores the evidence that even non-avian dinosaurs have air sacs like birds.... a feature not found in any other animal group.
I could go on but these five issues make this study extremely flawed and not really worthwhile to support your point.
By the way... I've actually read this paper, not just a news article on it.
Also, your footprints are interesting, but ultimately useless. There were lots of critters running around, how do you know they aren't from a dinosaur? Dinosaurs leave bird like prints after all.
Without offering a viable non-dinosaur alternative to origin of birds, your points are essentially useless.
Where are your Triassic/Permian/Silurian/Carboniferous/Cambrian fossil birds?
