First bird
http://www.ucmp.berkeley.edu/diapsid...aeopteryx.html
150 million years ago
And people say that the ones they evolved from were around 100 million years ago...but how can you evolve from something that comes after you? Impossible!
Edit: even earlier
http://www.dailymail.co.uk/sciencete...years-ago.html and dinosaurs were just around since 250 million years ago so how could there be a first 'bird' from a dinosaur? They share a common ancestor like I said but birds didn't evolve from dinosaurs.
