Bird-dinosaur discussion

• Archaeopteryx's Relationship With Modern Birds ("here are the derived characters with which Gauthier (in his 1986 paper) unites Archaeopteryx with modern birds")
• Dinosaurian Synapomorphies Found In Archaeopteryx ("characters shared with/retained from dromaeosaurids and other related theropods and dinosaurs")
• Dromaeosaurid Archaeopteryx ("All this suggests that avian flight first evolved in arboreal theropods (where they developed big brains and forward facing eyes, features not found in flying insects and pterosaurs), and that some of the flying theropods lost flight.")
• Earliest beaked bird discovered ("Fossil remains of this bird were found in China last year, 1994, and paleontologists, astonished and excited by the discovery, say the findings could have revolutionary effects on thinking about bird evolution.")
• Earliest bird with alula found ("new fossil that shows the first evidence of aerodynamic flight in birds")
• Feathers, scutes and the origin of birds (Experiments show that the same protein (when missing before birth) that causes bird feet to stay webbed, causes reptile scales to become feathers.)
• More On The Dino-bird Link (Q & A)
• Very birdlike non-avian dinosaur found ("The new maniraptorid dinosaur, named Unenlagia comahuensis, is described")
• The problems with (the book) "The Origin and Evolution of Birds" (Separate ancestry for birds debated.)
