Pterosaurs to Birds: Organizing the material

Organizing the material

There is a huge amount of material in this blog and it is a challenge to organize it.
I will try organizing it by type of bird such as those from my Dec 17, 2010 post (which I have updated a bit recently). I will set up a separate thread for each and then add info to each thread.

Categories:
Flightless birds
Seabirds (Ichthyornithes line)
Waders/shorebirds
Aquatic birds (Hesperornithes line)

Waterfowl (Presebyornithid line)

Landfowl

Landbirds (general)

Landbirds (Owl)

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 scansoriopterygids that developed into basal pygostylia that developed into modern birds. A side lineage earlier developed from the long tailed pterosaurs to long bony tailed scansoriopterygids. That lineage went extinct. The category called coelurosaur dinosaurs includes only actual dinosaurs (eg. tyrannosaurs). It does not include birds. The fossil record supports the pterosaur-to-bird theory. The fossil record does not support the dinosaur-to-bird theory.
