[edit] Feathered Dinosaurs

There is not one undisputed "feathered dinosaur", much less any evidence to support the idea that feathers might characterize any significant portion of this Order. A parsimonious hypothesis is a careful, conservative option, not the most outlandish! Mdotley 13:15, 12 September 2006 (UTC)

Followup: The Reference given for the statement that all coelurosaurs probably had feathers actually says otherwise. Some of the examples cited may well be "secondarily flightless birds", which would necessitate an even LONGER evolutionary history, as flight would have to have evolved and then been lost.

A minority of paleoornithologists, mainly Feduccia and Martin (though Martin has backed down a bit in recent years), holds that birds and dinosaurs are unrelated. They believe protofeathers represent frayed collagen, though subsequent papers have demonstrated this to be false. The unabiguously feahtered dinosaurs, like dromaeosaurids, troodontids, oviraptorosaurs, etc, they believe to be non-dinosaurian. This is an exreme minority position, and is discussed at length (or should be) at Feathered dinosaurs. It doesn't need to be re-iterated on every one of the dozens of articles discussing a particular group of "dinosaurs" for which feathers are known.Dinoguy2 19:23, 14 September 2006 (UTC)

How do you know that "all coelurosaurians had feathers"? What fossils show this? Were they from China, by any chance? Ratso 22:49, 20 March 2007 (UTC)
