A summary of the basic ideas of this site

 Here is a summary of the basic ideas of this site:

Birds developed in a lineage from short bony tailed pterosaurs to short bony tailed scansoriopterygidae that developed into basal pygostylia birds that developed into modern birds. A side lineage earlier developed from the long tailed pterosaurs to long bony tailed  scansoriopterygidae. That linage went extinct.

And

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

And

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