This site presents the idea that modern birds developed from pterosaurs (rather than land-based dinosaurs).
This is a credible alternative to the current land-based dinosaur to bird theory.
Here is a summary of the basic ideas of this site: Birds developed in a lineage which extends from protopterosaurs (eg. Sharovipteryx) to pterosaurs (eg. pterodactyls) to primitive flying birds (eg. ichthyornithes, enantiornithes etc.) to modern flying birds (Neognathae) and modern flightless birds (Palaeognathae) AND The category called "coelurosaur dinosaurs" should include only the actual dinosaurs (eg. Tyrannosauroidea etc) and not birds AND The creatures called "maniraptor" (specifically those from Aviremigia to the present) are not dinosaurs but flying, andsecondarily flightless, birds, within the pterosaur to bird line.
AND
The fossil record does not support the purported dinosaur-to-bird idea. The fossil record does support the pterosaur-to-bird idea.
Note
This site presents the idea that pterosaurs (rather than dinosaurs) developed into modern birds. This is not an "evolutionism" vs. "creationism" issue. An "evolutionist" can say that the pterosaur to bird developments are due to neo-Darwinian means (random mutation and natural selection). On the other hand, a "creationist" can say that those developments are the acts of a higher intelligence. This site does not take a position on the "evolutionism" vs. "creationism" question.

Philosophy and Such
Like most people, I have philosophical ideas that go beyond the nuts and bolts of the scientific analysis of the origin and development of birds. There are larger questions that philosophers have grappled with since the most ancient times. If anyone is interested in my take on those more philosophical ideas, click here. But please realize that all the ideas of this site are pure materialist, scientific ideas supported by physical evidence and scientific studies.
