Tastes like T-Rex: Link between dinos and birds strengthens

The researchers from Harvard Medical School and Beth Israel Deaconess Medical Center in Boston sequenced seven tiny pieces of collagen protein and found a close match with amino acid sequences found in the collagen of present day chickens.

"Most people believe that birds evolved from dinosaurs but that's all based on the architecture of the bones," said John Asara, director of the mass spectrometry core facility at Beth Israel Deaconess Medical School and a Harvard Medical School instructor in pathology.
